Selecting Your Glass: In the Testing section of our product pages we list several test results with varying types of glass, from standard insulated glass to high performance glass. This information can be helpful in determining the right glass choice for your order.
Why Aluminum Lasts Longer: Aluminum transfers energy effectively. Wood and vinyl window makers have wrongly promoted this as a negative trait. Other window materials absorb heat and cold into the frame, causing that material to fail prematurely. This is especially apparent during season changes where swelling and shrinkage adversely affect a window’s performance. Aluminum deals with such stress in a positive way by releasing the energy that would normally cause material failure as it does in vinyl and wood. The fact is that very little energy is lost through the frame material. Aluminum is thermally stable in that it does not swell and shrink when the temperatures or humidity levels change. One might say that aluminum is a more intelligent window material in that it deals with such stress in a positive way by releasing the energy that would normally cause material failure as it does in vinyl and wood. The fact is that very little actual energy is lost through the frame material.
Passive Solar Energy: Because we have engineered our products for strength, larger sizes are possible. Huge glass expanses not only accentuate your view but also welcome more natural light into the room. More natural light = immediate energy bill savings.
Hybrid Energy Blockers: The perimeter frame extrusions and the glass panel extrusions are equipped with an energy-blocking polymer. This feature makes the Everest one of the most energy efficient performance windows on the market.
