When to Repair or Replace Your Sliding Glass Door

Replace Your Sliding Glass Door

When you want to have a stylish, luxury home, installing a sliding glass door can be your best bet. This door consists of large windows that can be opened and closed for seamless access from your indoor to the outdoor. Not only does it offer an aesthetic appeal to your house, but it also allows an easy indoor-to-outdoor transition, offers beautiful outside views, and allows the natural light to get in. But after quite some time of usage, the time will come when it needs to get fixed or replaced with a new one.

In this article, we will share five factors that indicate when you need to get your sliding glass door repaired or replaced:

1) If It’s Having Difficulty Opening and Closing

The reason you install a sliding glass door is that it allows you and your family to easily and quickly move outdoors from your home. But nothing can be more frustrating and annoying than your sliding glass door no longer serving its purpose. If you’re having difficulty opening and closing your door, it will be best to fix it or install a new one, especially if it’s severely damaged.

Here at Durabuilt Windows & Doors, we are dedicated and committed to transforming your home through innovative and stylish doors and windows. If you need a sliding glass door replacement, we’ve got you covered!

2) If It Has Damaged or Dirty Rollers

Did you know that the rollers are designed to make your sliding glass door run smoothly? They are attached on either side of your door that allows it to move easily and quickly. But the time will come when these rollers give in to wear and tear, where they have become dirty or ended up damaged over time. In this case, you can always clean it up first and only decide to replace it when necessary.

3) If the Whole Door Is Misaligned

The time will come when your entire sliding door becomes misaligned. There are a handful of reasons for this. For one, the rollers supporting the door may have moved off the track, or your door screws may have also gone missing over time. Finally, the whole door may have become loose or stuck, making it uneven. When this happens, you should contact our experts to inspect it so that you can make a more informed decision moving forward.

4) If It Has Broken or Damaged Glass

A broken glass pane on your sliding door is the most obvious sign you’ll have to replace it. Not only is it distracting to look at, but it will also harm you and your family. But apart from broken glass, you must also check for some minor cracks, a few scratches, or visible stains on the glass. If they have grown significantly over time, you must replace the door before it hurts any of your family members or guests!

5) If the Door Has Gaps

What’s great about a sliding glass door is how it allows you to completely close it while disallowing any air to pass through. As such, your cooling and heating systems won’t have to work harder in regulating your home temperature. However, if it starts to have some gaps between the door itself and its framework, you may want to consider fixing or replacing it so that you can maintain your home’s energy efficiency!

Conclusion

Your sliding glass door must always be in top shape and working order to maintain its aesthetic value and functional purpose. However, you will need a repair or replacement when your door is difficult to open and close, has damaged or dirty rollers, is misaligned, has broken glass, and has gaps. When you see one or some of these problems, be sure to work with a highly reliable contractor and have it fixed or replaced right away!

Redesigning Outdoors: Patio Or Garden Doors?

Redesigning Outdoors

Winter has come and gone, and now the sweet sounds of birds can be heard in the morning, followed by the quaint rustling of leaves. Rays of sunshine now also peak through your windows, making it the perfect time to finally step outside.

Your home likely has a terrace, patio, or other outdoor space, which serves as your connection to nature. Regardless of this feature, spending time outdoors will likely be a priority, especially considering the current pandemic’s effects. Nothing quite compares to a few hours out in the sun, safe and sound from others.

For this reason, you may want to consider upgrading your outdoor space—and the best way to start is to simply upgrade your doors! The most popular choices remain to be garden and patio doors, sparking a never-ending debate of what works best.

Understanding the key differences between the two is key to finding the right door for you, which is exactly what this guide holds. Let’s begin:

Patio Doors

Patio doors come in various modern designs, which is perfect for homeowners who wish to continue a theme of both contemporary and modern. However, patio doors can also come with floor-to-ceiling windows, which adds a luxurious touch of natural lighting and panoramic views of your gardens.

Patio doors are sliding doors, which open and close through sliding across secure tracks. This compact design is perfect for those living in tighter spaces, as you don’t need to leave room for doors that open and close. You’ll also be given better control over the ventilation, especially since these doors typically have built-in screen panels.

Garden Doors

For a completely luxurious look, garden doors offer a fairytale and romantic feature that all homes have. They feature two traditional door panels—one is used as the main entryway, while the other provides ample ventilation across the room.

Garden doors either swing inwards or outwards, perfect for homes with huge spaces. They also ensure privacy and security, because compared to patio doors, they’re built with more wood and less glass. Although primarily rustic and elegant, they come in a variety of options, and the final product can be done according to your preferences.

So What’s The Big Difference?

Both doors offer clear advantages, but your choice will ultimately come down to a small feature—hinges. As mentioned, patio doors only slide to open and close, while garden doors operate much like swinging doors.

Simply put, a careful analysis of your preferences is crucial to your final decision. Do you have a smaller space, but wish to bring in more natural light? Patio doors are the answer. Do you have ample space for the outdoors, and wish to prioritize safety and privacy over natural light? Invest in garden doors.

Remember: Before deciding, make sure to take your personal style and preferences into consideration!

Embracing More Of The Outdoors

Your chosen door can be customized according to your style preferences, which should include patterns, materials, and even colours. However, it’s important to make sure that your doors are installed professionally, as anything less can potentially ruin not only your home’s features, but compromise your family’s safety and security.

That said, for the best garden doors or sliding glass door replacement in Edmonton, Durabuilt Windows & Doors has you covered. We are a windows and doors connoisseur, dedicated to providing you with only the best. We build to withstand Mother Nature’s elements, thereby ensuring you gain only the best value for money.

7 Ways to Successfully Get Replacement Windows for Your Home

Replacement Windows for Your Home

If you see your energy bills skyrocketing or you find leaks all the time whenever there’s the slightest rainfall, it might be time to get those new home replacement windows. However, window installation isn’t something every homeowner knows to do; it’s essential to do your research and understand what it means to have your home’s windows changed and replaced.

If it’s your first time buying replacement windows for your property, here are seven key things that’ll help you get the perfect windows for your home.

1) Measure Accurately

The first downfall of shopping for windows has an inaccurate measurement. Be very particular about measurements so you can get the right size and specifications for the windows; it’s recommended to take different horizontal and vertical measurements of your window from the inside. This way, you won’t be rushing into any issues or expenses later in the installation process.

2) Talk to the Professionals

Right off the bat, don’t attempt to DIY the window replacement. Professionals are more knowledgeable about the safety codes and installation process while keeping your home’s structural integrity. Simply avoid any problems that may require you to shell out more from your wallet than you need to by hiring some contractors.

3) View Recommendations

Besides talking to the professionals, talk to the windows experts on the best home replacement windows on the market. You can also check fellow homebuyers’ reviews. The replacement windows are an investment, and you should only have the best windows installed in your home for security, functionality, and aesthetics.

4) Achieve Energy Efficiency

If the reason you’re getting replacement windows is because of the high utility bill, check out windows that will help with your home’s energy efficiency. With better windows, you’ll have less need for temperature-altering appliances like heaters and cooling fans. Overall, you can reduce your energy costs with ease.

5) Get Extra Glass Panes

Since you’re getting your windows replaced, why not get new and improved glass panes? Many designs feature double glass panes, but you could also consider getting triple glass panes or laminated glass panes. These variations offer a lot more safety, and the noise reduction can make your home feel a lot more peaceful.

6) Ensure Window Insulation

Having proper insulation in your replacement windows should also be a priority to prevent energy loss and make your home’s temperature ideal. Ask your contractor if your home would benefit more from pocket installation or full-frame installation. This may also depend on the condition of your window’s framing and whether it’s durable enough.

7) Take Note of the Warranties

Just like with other purchases, warranties are offered to reassure clients that they’ll have the best experience with their products. Different window manufacturers in the industry can have different types of contracts, so keep an eye out for what your windows’ warranty includes.

Conclusion

You don’t have to worry about high energy bills or any sudden leaks by your house’s openings. By following the tips in this article, you’ll have the highest-quality windows that fit your home like a glove.

Window Replacements in Canada: Our Basic Guide

Window Replacements in Canada

Owning a home is never an easy experience because of all the different things you need to worry about throughout the year. Whether you live in a duplex, mansion, apartment, or bungalow, owning a home will always involve dealing with various chores, tasks, and maintenance-related work. From regular processes like heater maintenance and pipe cleaning to external painting and light replacements, there are likely many different items on your list that you can expect (or not) to handle.

Out of all the different tasks and concerns of homeownership that you need to worry about, here’s one home improvement job worth knowing more of: window replacements.

All You Need to Know About Window Replacements

Although it may not necessarily be the first thing that comes to mind when you think about “home improvement,” there’s no doubt that it’s something that you’ll need to deal with sooner or later.

Considering that windows themselves have a specific shelf life because of the conditions that Canadian weather poses, it’s important to know how the entire process works and when it’s warranted. Unfortunately, most people overlook the need to do so and end up jeopardizing their safety and comfort.

When Should You Get Your Window Replaced?

The trickiest part of window replacements is knowing when you should call Durabuilt Windows & Doors’ experts because you may not be well-acquainted with the process as you are with other common home improvements. As with any other home improvement job, however, the need for this type of process always boils down to a few key signs to watch out for:

  • There is air seeping in from the edges (which is often suggestive of a leak)
  • The windows are no longer energy efficient (which is associated with age)
  • The property’s curb appeal needs to be increased
  • The insulation in your home needs improvement because of rising temperatures (or lowered ones during the colder months)
  • The window has sprung a leak

By keeping an eye on these key signs, you can ensure that you don’t unwittingly put yourself in bad situations in the comfort of your home!

What Happens During a Replacement?

When you call a Canadian window replacement expert like Durabuilt Windows & Doors to take care of your window replacement-related needs, you can expect to witness this meticulous step-by-step process:

Step #1: Old Window Removal

Like any other type of replacement, the process in question involves a full removal of the old window before a new one is placed. After an expert removes the trim from around the windows, the panes themselves are lifted out, followed by the screws that hold the pane itself.

Step #2: Opening Preparation and Positioning

After full removal, the window replacement experts carry on with the process by preparing the slot where an old window used to be and positioning the replacement. By following this particular procedure, it will be much easier to ensure that the finished job holds up to a stronger set of standards and performs as best as possible so that no back jobs occur!

Step #3: Insulation and Waterproofing

Now that the meat of the window replacement is taken care of, the necessary finishing touches are applied so that everything is airtight with insulation and waterproofing. At Durabuilt Windows & Doors, we take this process very seriously because of how much it can impact the procedure’s resulting experience!

Conclusion

While it may not necessarily be something that’s as familiar as a piping job, driveway cleaning, or house painting, window replacements are a type of home improvement project that must be on your priority list. Through this guide’s help, you’ll keep yourself equipped with everything you need to know about approaching the process in question with the right mindset so that you can make the most out of it when the time for a replacement comes!

Door Replacements: When Should You Have Your Doors Replaced

Door Replacements

Nowadays, people go in and out of their homes through their side doors and garage, making them forget about their front doors. Front doors are often used to welcome guests into a home, and since it doesn’t happen regularly, you might be ignoring signs of wear-and-tear.

These defects can significantly affect your home’s curb appeal, energy efficiency, and, most importantly, your home’s security. While most people are aware of when they need to replace their energy-wasting windows, few are knowledgeable about front door replacements.

Because of this, you may be missing out on fantastic door improvements that could enhance your home’s aesthetics, have better security, and have improved energy-efficiency that could benefit your home.

Luckily, you can easily have your doors upgraded, thanks to companies like Durabuilt Windows & Doors, which specializes in door replacements, enhancing your home’s visual appeal, protection, and more.

Unquestionable Signs Your Door Needs to Be Replaced

Sign #1: There is Space Around or Under Your Doors

When your windows are closed and shut tight, light and air shouldn’t leak through its casing, which also applies to exterior doors. Ideally, your doors should keep light and other external factors, such as water, air, insects, and critters, from entering your home.

When you have gaps in your doors, these environmental factors can seep into your home and affect your comfort. Besides that, it significantly affects your energy-saving efforts since it messes with your temperature control indoors.

Sign #2: There are Obvious Physical Damage

Doors aren’t immune to wear and tear; in fact, damage can be caused by a plethora of factors. However, if you notice the following signs, you should consider having your door replaced:

  • Dents: This can affect your security since your door isn’t as durable anymore.
  • Rusting: Rusting can compromise your security as well since it isn’t strong enough to protect your home’s interiors due to its fragile state.
  • Peeling and Spitting: Wood doors don’t age well; because of that, they are prone to splitting and peeling. Besides ruining your home’s aesthetics, it also invited termites and other wood-destroying critters to your home.
  • Squeaky Hinges:  When you start hearing squeaky sounds, it’s time to get door replacement services since it is a huge threat to your security, allowing intruders to enter your home easily.

Sign #3: Your Door is Not Functioning Properly

Your door has a simple yet very vital job, and it’s to protect you and your loved ones from the outdoors. When you can’t lock your door properly, you might think a simple knob and lock replacement may do the trick.

However, it’s a much better idea to upgrade your whole door altogether for a stronger and more secure door. And if you’re having trouble opening and closing your door, take it as a sign to have your door replaced.

The Bottom Line: Don’t Sleep on the Integrity of Your Door

Many people find it useless to have their doors replaced, especially if they don’t use them often. Keep in mind that even when you don’t use your doors all the time, it can still be vulnerable to damages that could put you at risk for security dangers and more.

So if you notice some of these signs, it’s best to get your door replacement services and ensure that your home is well-protected and is in top shape.

Nice frames! Who prescribed your Glass?

Have you purchased eye glasses recently? The selection of eyeglass frames is truly remarkable – high performance materials, durable and stylish. And I bet you bought the most fashionable pair, they looked perfect on you, and fit perfectly. And when someone said to you the next day – hey, nice glasses, it made you feel good about your purchase. I bet no one has ever said, nice lenses. But, why do you buy glasses? Because you can’t see without them!

Did you prescribe your own lenses? Of course not. What we do is go to the eye doctor; he or she turns down the lights, makes us read some letters on the wall, drops a machine in front our face and he flips down lenses and ask us – is that one better? How about this one? When it’s all done, he writes us a prescription.

If we prescribed our own lenses, we might pick the wrong ones and won’t be able to see through them. Although your frames look great, it’s the lenses that are real performance component.

It’s pretty much the same with windows. Once you replace your windows, your neighbours will come by and say, nice windows – and they will probably be talking about how the windows look. And although the looks are important, it’s the glass where you can best impact your year-round performance. No one will ever say, nice glass – however, it’s the reason you buy windows in the first place. We want to be able to look out of our homes and let natural light in.

So what is window performance? What if the temperature around your windows was the same as the middle of your home? You’d be comfortable – they would be performing.

With today’s window technology, you have the ability to get the performance and comfort you want – and the sales professionals, or window doctors, at Durabuilt can help you.

If you are looking to replace the windows in your home, you’ve already had experience with your present situation. Maybe you have a north facing living room window that is too cold to sit next to during the winter. Or, you have a southwest facing nook window that overheats your eating area during dinner in the summertime. Or, you have a bathroom window that always has condensation on it – especially in the dead of winter. Give thought to the areas that are causing you to be uncomfortable and get ready to write your comfort prescription.

Let’s start talking about your wintertime performance. So what happens during winter? It cold! The sun gets up around 8-8:30 and goes down around 4:30-5. The suns doesn’t really rise up – it basically hovers around the landscape, it lays low, and although it can provide some nice heat gain during the day the reality is that it is dark most of the time – and the nights are cold.

Have any of you stood beside a dualpane window in the winter and even though the window is closed, you can feel a draft? The reason is simple science. Heat runs to cold and your dualpane windows are the coldest area of the house. As heat comes up to the window it rises up, pushing the cold down – and it circulates around the window. In addition, the heat from your body is being pulled away from you toward the window; it makes you feel chilly – not comfortable.

So, what can you do to improve you wintertime performance?

For maximum wintertime performance, you want to choose windows with a low total window U-value. You may not have heard about the term U-value. Have you heard about R-value? Insulation? R-value is the resistance to heat flow and the U-value actually measure the heat loss – it is the inverse of the R-value.

Total window U-value measure the three areas of the window – the frame, a 2” inch band of glass next to the window frame and the rest of the glass. Think of the frame, the edge of glass and the rest of the glass as “building blocks” to help prescribe the level of performance you need.

First, pick a window frame the uses low conductivity materials. What is does that mean? Heat passes through material by the means of conduction. Do any of you have a cast iron frying pan? Ever notice that the handle gets pretty hot when you are cooking? Well, the heat of the pan is moving to the colder handle – cast iron is high conductivity material.

Vinyl window frames are both strong and low conductivity. Vinyl windows have airspaces, or warm air chambers, in their design to provide warmth and strength.

Now, the edge of glass. The 2” band of glass at the edge of the frame is affected mostly by the type of spacer bar use for the insulated sealed unit. A sealed unit is 2 or 3 pieces of glass separated by 1 or 2 airspaces and it sealed to ensure no moisture gets inside the airspaces. In fact, the airspaces provide natural insulation. The first sealed units were made using an aluminum spacer bar, which is a high conductivity produced and made the edge of the glass cool, resulting in an increased chance of condensation.

At Durabuilt, we use Super Spacer® – the warmest spacer bar. Made of structural silicone, this no-metal spacer is a low conductivity material means the edge of the glass will be warmer, which means less chance of edge condensation and an overall better performing window.

Now, the rest of the glass. This is the area that provides the most “building blocks” to improve your comfort – it is the largest area of the window. Let’s begin with the true performance layer know as low-e. These sophisticated, virtually transparent coatings, on the glass are protected inside the airspace. Low e means, low emmissity – it allows for low levels of heat transfer, or basically pushes heat back to its source. And there are different types of Low e, so we can prescribe the performance you want. At Durabuilt, we manufacture your insulated sealed units using two types of PPG Low e coatings. Sungate 400® helps retain the heat from your home and allows for solar heat gain – a source of free energy. Solarban 60® does a slightly better job at retaining heat and reflects a large portion of solar heat providing summertime comfort and reduced cooling costs – wintertime and summertime performance.

In addition to the Low-e coating, we fill the airspaces with argon gas – which is 30% more dense than air, so it slows down the transfer of heat. In fact, when you add argon a dualpane low-e window sealed unit, it increase its insulation value by 15%.

When you choose triple pane glass, three pieces glass with two sealed airspaces, you get an extra layer that can have low-e and an additional that you can fill with argon gas.

So when it comes to wintertime comfort, you have the building blocks of the windows frame, it’s spacer bar, airspaces, low e coatings and argon filling to write your performance prescription.

In Canada, we use two methods to measure window performance – U-value and Energy Rating. The U-value is the rate of heat loss through windows under standardized winter conditions and does not take solar heat gain into account. The ER is an overall energy balance rating that takes account of passive solar heat gain in addition to heat loss.

How about summer? Long hot days, lots of sun light – up around 5:30-6, goes to bed around 9:30-10.

The goal in the summer is to keep the heat outside – not let it in the house. Ever stand beside a dualpane window in the summer when the light and heat were pouring through it? I bet you didn’t stand there very long. An easy way to think about heat gain is; if you’re in your home and the light from the sun is coming through the windows, it is also allowing for the sun’s heat and damaging ultraviolet to enter as well. On the other hand you may have large overhangs or trees that block the sun’s heat – however, it is blocking its much valued light as well.

A windows ability to block solar heat is measured by a term call the solar heat gain coefficient. Sorry about that; don’t worry it’s not as complicated as it sound. If you stand outside your window the solar heat you feel is given a value of 1. When you go inside, the same heat that you feel behind the window is the solar heat gain coefficient. Standard dualpane glass let in about 80% of the solar heat. Solarban 60® low-e blocks about 60% the solar heat, dramatically reducing heat gain. If you choose triple pane, you can have two surfaces of Solarban 60® low-e and reduce the heat gain even further to about 70%.

In addition, it blocks about 85% of the damaging UV rays. With the increased amount of sun’s hours relates to the potential for a lot of heat and UV gain. You need to protect your level of comfort and your valuable furnishing, floors and drapery from premature fading.

Some people think that they don’t need heat blockage in the summer because the have air-conditioning. First, air conditioning cost money to run. Secondly, if you sit down next to a window where the sun’s heat is pouring in through the window and the air conditioning is blasting up through the floor – it’s like you’re sitting on a block of ice and your hair is on fire – it’s not comfortable.

We’ve looked after your wintertime and summertime performance. Well, fall is part summer and part winter, and spring is part winter and part summer. Now we are ready to prescribe you windows so you get year-round, all-day performance.

Two residual benefits of choosing high performance windows include getting to use all your floor space – you can position your furnishings next to the windows, enjoy the light and gain back some space. Additionally, high performance windows result in wintertime energy savings, year-round if you have air conditioning; and as energy costs go up, so do your savings. Think about your new windows as a long-term investment, that immediately returns comfort and living space and energy savings.

Window performance testing – A basic overview of NAFS

The North American Fenestration Standard/Specification, or NAFS, is the recognized standard for testing, rating and labelling of windows, doors and skylights for residential and commercial buildings in Canada.

The official name is AAMA/WDMA/CSA 101/I.S.2/A440, “NAFS – North American Fenestration Standard/Specification for Windows, Doors and Skylights” In Canada, an additional supplement is used to address specific Canadian performance conditions.

NAFS at a Glance

NAFS features a comprehensive method to classify the type, class and performance of windows and doors. Any product that has not been tested to NAFS does not meet the 2010 National Building Code of Canada, or provincial revisions.
Some of the main components of NAFS includes;

Performance Class
There are four performance classes: R, LC, CW and AW. Building type, load requirements and serviceability determine the Performance Class of the windows and doors and is set by the building architect, designer or specifier as;

Residential | R – Light duty, commonly used in single-family dwellings.
Light Commercial | LC – Medium duty, commonly used in low-rise and mid-rise multifamily dwellings.
Commercial Window | CW – Heavy duty, commonly used in low to mid-rise multifamily dwellings where limits on deflections are imposed and tougher environmental constraints exist.
Architectural Window | AW – Severe duty, used in high-rises or when extreme use of fenestration is expected.

Each Performance Class (R, LC, CW and AW) has minimum test sizes and minimum test pressures known as Gateway Requirements. Every product must be tested for each Gateway Requirement in order to qualify for a Performance Class.

Performance Grade
The Performance Grade is a single number that represents performance attributes for a number of different tests including design pressure, water penetration resistance, air leakage resistance, operating force, durability and life-cycle test. The Performance Grade is determined by;

Geographic location – Performance requirements are calculated to determine minimum design pressure, water penetration resistance and air leakage resistance based on the site’s geographical location

Building height – Determined from the top of the window or door above grade, with a minimum height of 10 metres.

Exposure condition – Determined as either;
Open terrain – level with only scattered buildings, trees or other obstructions, open water or shorelines.
Rough terrain – suburban, urban, or wooded terrain extending upwind from the building uninterrupted for at least 1km or 20 times the building height, whichever is greater

The NAFS Canadian Supplement includes a table that lists all major cities in Canada to help building professionals select the right Performance Grade. An easier method is to use the Fenestration Canada NAFS calculator – go to http://www.fenestrationcanada.ca/calculator and click on the fenestration performance calculator.

Energy Code 9.36 – Where Do Windows and Doors Fit in?

Section 9.36 of the National Building Code details new requirements for housing and small buildings that is focused on improving the energy efficiency and reduction of greenhouse gas emissions. The code references six climate zones. The prairies have four of these zones. The specific weather location may be determined by referencing Appendix C of Division B in the Code or by consulting the local authority.

Compliance Map

Compliance Paths

Energy Code 9.36 includes three paths for compliance; Prescriptive, Trade-Off, and Performance Compliance. Select only one compliance path; multiple compliance paths are not permitted on a single building.

Prescriptive Path – The acceptable level of building energy efficiency by constructing the minimum requirements. This path involves following the prescriptive requirements of Subsection 9.36.2, 9.36.3 and 9.36.4 and is typically the simplest compliance path. It involves meeting all requirements in that part, but might not be appropriate for all buildings.

Prescriptive / Trade off Path – The acceptable level achieved by swapping of one or more building envelope thermal performance requirements, resulting in no worse thermal performance than if the affected assemblies met prescriptive requirements. If you need more flexibility in your design, a trade-off path allows you to trade elements within the above ground building envelope to demonstrate an equivalent level of performance without meeting every prescriptive requirement.

Performance Path – The acceptable level by employing a computer simulation software or calculations to compare a proposed design with a hypothetical reference building to show that the proposed design will use less energy over the course of an operational year. Once construction of the house is complete, a blower door test is performed and a Natural Resources Canada EnerGuide Rating System label is issued.

How do windows and door fit into Energy Code 9.36?

The Code allows windows and doors to qualify under two different energy performance rating methods: by the total unit U-value, and by Energy Rating (ER).

The U-value is the rate of heat loss through windows under standardized winter conditions and does not take solar heat gain into account. The ER is an overall energy balance rating that takes account of passive solar heat gain in addition to heat loss.

The ER is intended for use in homes with average window-to-wall ratios, and an approximately even distribution of windows on all sides of the home, and no external window shading devices. In such homes it has been shown to be more effective for selecting windows for lowest year round energy use. The ER is not recommended for homes with higher window-to-wall ratios (above 30%), or with windows facing primarily one or two orientations. Under these conditions occupants could face heating discomfort, or fail to obtain the benefits of moderate passive solar heat gain.

For homes with high window to wall ratios, or windows primarily facing one or two orientations, windows should be selected on the basis of U-value, and with consideration to reduce occupant discomfort from excessive solar heat gain by use of external shading or glass with lower solar heat gain.

There is some flexibility that allows trade-offs, in which a better performing window or glass door can compensate for a worse-performing product having the same orientation. It also has a performance path, and it is possible that homes designed under the performance path could accommodate several products that have worse than prescriptive ratings. The code also relaxes the U-value requirement for one door in a home. The intent is to allow decorative or heritage style entrance doors to be used which might be constructed of materials that cannot achieve the prescriptive U-values.

This table provides the maximum U-value and minimum Energy Rating for your building zone.
