South Calgary | North Calgary

If you’re asking yourself the following questions,
you are ready for window replacements for your Calgary home.
u

Are my windows efficient enough?

u

What can I do to reduce my energy bills cost in the wintertime?

u

Do I have good or bad windows, and do my windows leak air?

Many homes in Calgary, Alberta have double and single pane windows. The single pane window has been around for centuries, and if you have one in your home, you probably know by now how cold it gets when the winter hits Alberta.

The double pane sealed unit with argon gas was introduced in the 90s and was one of the most popular options for home builders and window replacement companies.

It introduced a new era of energy-efficient windows and was a huge improvement when compared to single pane windows or regular double pane windows without argon gas.

Although the tri-pane (triple pane) window replacement was already an option for some manufacturers, the cost of manufacturing and installing was double to triple compared to a regular double pane window and not many homeowners could afford it then.

Now, let’s talk about triple pane window replacements more in-depth and discuss the benefits, how it’s compared against the leading double pane glass units and mainly, will your home benefit from a triple pane window.

Sunbusters Inc. is a certified JELD-WEN® supplier and installer for tri-pane and double-pane window replacements in Calgary.

Let’s compare a picture window and a casement window from the double and triple pane Willmar™ collection side by side and see the difference with our own eyes.

You are probably asking yourself, what is this chart, and what advantage can I have? We explain the meaning of each Column and its value below.

U-Factor indicator for our windows in South Calgary

U-Factor

U-factor indicates the amount of heat that the window will lose through the glass.

As you can see, there are 2 Columns, U1 stands for Imperial, and U2 is Metric. These are the same values, one in metric and the other in imperial.

Solar heat gain coefficient windows in South Calgary

SHGC

Solar heat gain coefficient is a ratio of solar heat allowed through a window. The amount is between 0 and 1 where 0 is the least amount of solar heat allowed and 1 is the maximum solar heat allowed through a window.
Visual transmittance chart for window glass services in South Calgary

VT

Visual transmittance is the measurement of how much visible light is transmitted through the window glazing. The higher the value the more visible light is allowed through.

ER

The energy rating is the balance between U-factor, SHGC and air leakage. Higher numbers in this column mean the window is more efficient.

Comparison

Now that we know a little about the windows, let’s compare.

We have a given double pane (glaze) Picture window with Low E 272 and argon which has a u-factor of 1.42, and a tri-pane window with 2 coats of Low E 272 and argon, which has a U-factor of 0.91.

Percentage of Efficiency

Let’s do some math to get the percentage of the efficiency.

1.42-0.91=0.51

0.51/1.42=0.3591

0.3591×100=35.91%

Save Heat, Save Money. It’s Simple.

So, let’s imagine a scenario here in Calgary, Alberta where you have even older windows, the single pane on a metal frame, that we don’t even know what the U-factor is (much worse than U2 of 1.6 but in this case, we will stick to this number) and you upgrade to a tri-pane window you will be saving more than 43% on your heat loss. Yes, we are talking about heat loss because that is the most important feature to maintain the heat your furnace is producing and reduce the amount of money you spend on gas bills in the wintertime.

You know the saying time = money, right? That’s exactly what this is all about. Contact us today

Save the amount of time your furnace will work, save on gas consumption, and make your new windows pay for themselves.

Over the years we had tens, if not hundreds, of customers thanking us for our great window installation and superb product.

The biggest saving we have heard about was a drop from 520$ to 300$ when compared to the same consistent -25 weather condition. That’s 120$ back in your pocket every cold month for years to come.

With the right company in mind and one of the leading window manufacturers in North America, a window replacement project shouldn’t be stressful or very expensive.
