Understanding the glass options
According to the Consumer Federation of America, the average American household spends $1,500 per year on energy costs. But energy-efficient windows can help save a bundle. In fact, you can reduce your energy bills by one-third by simply using low-emissivity glass.
Clear Glass

Clear glass units provide optimum noise protection compared to single pane glass. In terms of temperature resistance, it easily allows hot and cold air from both the inside and outside to flow through it smoothly.
Low E-Glass: Blocks cold lets in light

Regardless of where your home is located, choosing windows that provide you with the highest level of comfort and energy savings year-round is extremely important. And choosing the right glass for your windows is the most important factor in the decision.
When the weather turns frigid, LoĒ glass is the perfect cold remedy. It provides excellent insulating capability, blocking heat loss to the outside and reflecting heat back into the room. What's more, it's the ideal glass for passive solar applications because it allows the winter sun's heat to pass into the home. LoĒ is the ideal choice for passive solar designs.
LoDz: The clearest choice for total comfort

Whether it is 20 below or 110 in the shade, you can bring year-round comfort to your home with LoDz-272® glass. In winter, LoDz-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.
Hot or cold outside, comfort inside

The insulating effect of your windows has a direct impact on how your rooms feel. Typically, 75% of the exposed surface of a window is glass, and the temperature of the room-side of the glass directly affects the air temperature in the room. Therefore, the better insulated the window glass, the warmer your room will be.
The insulating value of LoDz-272 is nearly double that of an ordinary insulating glass unit, or the equivalent of a quad-glazed window!
LoDz-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 LoDz-272 glass to comfort you and your loved ones on the inside – all year long.
Super Spacer

The edges of a window's insulating glass are the most vulnerable to heat and cold loss. After the wear and tear of time, this leads to condensation. This extra moisture is detrimental the whole window assembly; creating stained wood, peeled paint, rotting frames, mold and variety of other problems. Your average single-sealed insulating units are constructed with only one types of sealant. This is an ineffective construction method, because they are called upon to perform a double duty. Not only must the sealant provide resistance from moisture vapor, but it must also act as adhesive for the whole unit through a variety temperature changes. The Super Spacer is a revolutionary insulating glass spacer. Vinyl-Pro is one of the few manufacturers around the world who carry this product. And we use it exclusively in "Optima" series window assemblies. It uses a patented dual seal insulation system, which provides powerful adhesion as well as sturdy resistance to moisture vapor. No double shifts – the Super Spacer has a seal to get each job done properly. The result is a staggering reduction in condensation and comfortable household humidity all year round. The results are unparalleled by any insulating glass unit on the market!
