Double Hung Tilt Windows

The ultimate glass for comfort at home. Whether it is 20 below or 110 in the shade, you can bring year-round comfort to your home with LoĒ²-272 glass. In winter, LoĒ²-272 reflects heat back into the room. In summer, it rejects the sun’s heat and damaging solar rays. Additionally, it is the clearest, highest performing glass you can buy – without haze or a bluish cast.

Weather will never bother you again, since the LoĒ²-272 coated glass reflects the outside harmful rays back, and keeps the heat indoors. You can see an example of the difference in temperature when using the LoĒ²-272 below.

It’s like an invisible insulation! The insulating value of LoĒ²-272 is nearly double that of an ordinary insulating glass unit, or the equivalent of a quad-glazed window!

LoĒ²-272 even outperforms the tinted glass often used in warm, sunny climates. You see out and the light shines in, with no heavy bronze or smoke-colored tints to darken the personality of your home.

Really, no matter what it is like outside, you can count on LoĒ²-272 glass to comfort you and your loved ones on the inside – all year long.

The efficiency of a windows and doors must take into account the weather conditions. Different climates demand windows with different characteristics, namely expressed in terms of unwanted heat losses (U-Factor) and unwanted heat gains (SHGC).

In cold climates it’s particularly important to use low-E coating glasses to reduce heat losses through the windows.

In hot climates the most important is to use Low E2 glasses to limit solar heat gains (low-E2 glasses are particular efficient in reducing the infrared and some ultraviolet rays, besides being good insulators and transmitters of visible light).

Heating and Cooling Energy Savings

A spacer is the component, or piece, used in window manufacturing that separates and seals the two panes of glass in an insulating glass (IG) system. Its intent is to insulate your windows to help maintain an ideal temperature during the seasons you heat or cool your house.

Historically, spacers commonly contained metal, which manufacturers thought provided more durability for their windows. However, what happens with a metal spacer – even one containing aluminum – is that it acts as a conductor. In other words, the metal acts as a catalyst to the very thing it was trying to prevent.

Super Spacer is a true dual seal warm edge spacer system that uses a high-performance acrylic adhesive for its structural seal, backed by a moisture vapor seal. Two seals are better than one – proven by the fact the windows made with Super Spacer last five times longer in durability tests than single-seal units.

Unlike metal spacers, Super Spacer can bounce back when put to the test against winds, temperature fluctuation, rain, snow and UV light. The foam construction of Super Spacer allows it to expand and contract as need, but always return to its original shape. Without Super Spacer’s 100 percent memory formula, windows can eventually crack and lead to seal failure.
