Our T-Core insulated frames are stronger and more durable than ordinary vinyl frames. Typical vinyl frames are hollow and weak. Our T-Core insulated frames are different. With a dense thermal foam core and welded frame that uses no screws or caps, our windows never bow, sag or warp.
We don't stop at the frame when strengthening our window components. Our C-Core Reinforced Sash uses composite reinforcement inside stiles and rails. At 400 times stronger than a hollow sash, Performax54 sashes will never warp, bow, or twist. The secure fit of our sash within the window frame helps to greatly reduce any possibility of air infiltration.
Our exclusive SolarGold Spacers are simply more energy-efficient than any others on the market. Most spacers are made out of metal and transfer the outdoor temperature indoors. By utilizing non-metal spacers, we eliminate seal failure and conductivity, increasing energy efficiency. We guarantee no seal failure for a lifetime because of our spacer.
Our Thermostat Glass has three layers of low-e coating that act as an invisible shield protecting against Mother Nature, noisy neighbors and UV rays. Most windows max out at two layers. Adding a third layer of coating makes our window 50% more energy efficient than others.
