The Super Spacer® is the world's first and only all-foam, no-metal window spacer. Unlike most dual-paned windows made with heat-conducting metal spacers, windows with the Super Spacer® minimize heat transfer, keeping your home cooler in the summer and warmer in the winter.

The revolutionary Super Spacer® design ensures that the spacer will expand and contract, but it will always maintain its structural integrity by returning to its original shape. This is very important because windows are constantly exposed to temperature changes, UV ray bombardment, barometric pressure changes, and wind load. Other rigid spacers containing metal don't allow for the natural expansion and contraction that must occur in the insulating glass unit to offset the effects of these pressures on the glass. The results are stress cracks that eventually lead to seal failure. Super Spacer® windows don't fail, which means your windows never fog and will hold special gas fills such as Argon for the full life of your window.

Best of all, Tropical Wholesale doesn't charge for this fantastic feature—it is included standard in all of our recommended windows. That's right—we give it to you for FREE!
