Low Emissivity Glass – Energy Efficient Options

Low Emissivity Glass

Low-E Glass

There are times it can be tough to make all the right decisions when ordering windows (one of the many reasons to makes rue you get the right contractor/installer). You’ve decided on what type of window you’re looking for, you know the grid pattern, the color, the series and then on top of that you’re asked what type of glass you want!  This article will help you answer this question and understand what  Low Emissivity glass is and how it is used.

Climate Solutions specializes in using Low Emissivity (Low-E) glass which has a coating on one surface of the glass that reduces energy transfer.  In layman’s terms  that low emissivity/energy transfer means it significantly reduces hot or cold transferring through the glass (and in or out of your home).

Low Emissivity

There are three main Low-E coatings we use, LoE-272, LoE-366 and i89 glass, all of which perform differently and can be combined to easily exceed Energy Star 2016.

First of all – the science behind it:  The sun gives out lots of Thermal radiation which is reflected by  the multiple layers of silver in the coating on the glass.  Simultaneously, longwave radiation from inside your house, for example radiators, flooring and even body heat, is prevented from escaping by the glass – this means your house keeps inside temperature consistent without letting the outside temperature influence it.

The benefit is clear – the less energy you lose through poor glazing the more efficient your home will be.  The more efficient your home, the lower your energy bills.  With Low-E Glass you can save up to 25% on your energy bills.

LoE Glass Types

What’s the difference between LoE-272, LoE-366 & i89?

LoE-272 and LoE-366 are soft coats that go on a surface that is inside the glass unit (so it can’t be touched).  The i89 is a hard coat that is on the interior surface of the window, the one that faces inside the home.  Because it is a specially formulated hard coating it is tough enough to be exposed, but it is only used in combination with the other types of glass – LoE-272/LoE-366.

In its simplest form it is down to the number of layers – LoE-272 has 8 layers in its coating, whilst LoE-366 has 12 layers.  These layers are what do the work of reflecting the heat all the while letting light into your home.  The glass with more layers, LoE-366 performs the best.

This is measured in three ways, that appear on your NFRC label – U-Factor (basically energy-efficiency – the lower the number the better), Solar Heat Gain Coefficient (how much of the sun’s heat gets through the window, the lower the number the better) and Visible Transmittance (how much light is obstructed by the window, the higher the number the better).

Energy Star®

Using LoE-272 will make an enormous difference compared to regular clear glass, or even hard-coat LowE products, but the clear winner is LoE-366.  Here you can see that LoE-366 is the only coated glass that performs to Energy Star standards in all climate conditions in the United States:

Energy Star Low-E Glass

To put it in practical terms – when it’s cold you’ll stay warmer and when It’s warm you’ll keep the cool in your house – here’s a table showing what the relative temperature difference will be using the LoE-366 glass:

Low-E Performance

If you have Southern or Western facing windows then we’d particularly recommend using LoE-366 because it will provide greater protection against the infrared heat rays from the sun.  Again, without using too much scientific terminology what does this mean for you?  Well, it will reduce the harmful effects of those rays and the benefits include less heat coming through and even protecting your furniture and fittings from light-fading.

To ensure that Energy Star is hit and exceeded the recommendation is pairing the LoE-366 and the i89 together – with this combination every Climate Solutions window and door is guaranteed to exceed Energy Star standards.

Once you have chosen which Climate Solutions vinyl window or door you are going to go with, whether it is the Tilt and Turn 6000 Series, the 7000 Series, the 8000 Series or our 9000 Series Patio Doors there are still a number of decisions to be made.

What makes Climate Solutions Windows and Doors unique is our ability to completely customize the windows and doors we manufacture to the exact specifications required.  This goes from the hardware to the glazing, from the dimensions to the screen types, but the option that has the biggest effect is the finish on the window itself.

paintable stainable

We offer a real-wood finish with our Paintable-Stainable range, giving all of the benefits of wood design while still getting the performance (and price) of a vinyl window.  For a simpler option there’s our range of laminated woodgrain finishes, which come in Light Oak, Dark Oak and Cherry.

Custom Colors

Unlike many manufacturers, we Climate Solutions are not limited by the colors we have an offer.  As well as house colors of White, Almond, Bronze, Coco, Royal Brown & Black we are also able to offer truly unlimited custom colors for exterior finishes.

Having the ability to match any color gives huge advantages, whether it’s because you’re only replacing some windows in an existing home or have strict association codes to keep to – as long as you have a sample we can match it.

Like all of our products and options, the Full Spectrum Color Lab is made with one message in mind – Full Quality that is Fully Customizable. We are here to make the vinyl windows and doors that you specify, not to fit a product around you.
