Explore the Benefits of Unix IQ Glass

Cost Savings

Unix IQ™ with Super Spacer® technology which helps block heat and cold from passing through the window system. By keeping the elements from passing through, you will use less energy to heat and cool your home. This translates to savings on your energy bills and gives those temperature swings the boot.



Unix IQ™ with Super Spacer® technology is a dual-seal system that is known to last up to five times longer than single-seal systems. One week spent in a P-1 chamber is equivalent to one year in the field. Since Unix IQ™ survived 125 plus weeks, well let’s just say that you will enjoy a lifetime of comfort, energy savings and quality performance from your new Windows.

Noise Reduction

If you live next to a busy road, have restless neighbors next door, hear airplane noise overhead or power tools blasting on a Saturday morning, Unix IQ™ technology helps keep it quiet inside your home.
