What is a spacer?

CS Ultra Spacer

The spacer system you choose is just as important as the window! Windows are comprised of two panes of glass separated by a spacer that hold the panes together, creating an insulating air space where a safe gas such as argon or krypton can be added to protect the home from heat loss and outside elements. CS Ultra Spacer™ provides the warmest window edge with maximum durability, seal failure resistance and energy performance. CS Ultra Spacer™ gives you a true dual-seal system that is exclusive, patented and the warm edge will last a lifetime.
CS Ultra Spacer technology is a dual-seal system that is known in the industry to last up to five times longer than single-seal systems. Its structural adhesive plus perimeter edge moisture vapor seal equals the most reliable insulating glass unit on the market today.
CS Ultra Spacer provides the warmest window edge for maximum condensation resistance, durability and energy performance.
Whether it is cars whizzing by, restless neighbors next door, airplane noise or power tools blasting on a Saturday morning, CS Ultra Spacer technology helps keep it quiet inside. That’s because the closed-cell polymer foam in CS Ultra Spacer transmits very little sound compared to conventional metal spacers. Just another reason you’ll be more comfortable in your home with CS Ultra Spacer window systems.
