TempSmart™ Spacer
It is a flexible, U-shaped, silicone foam tape product used to wrap around and cushion our center decorative panel. Featuring a vapor barrier backing, the product used in combination with Hot Melt butyl, provides a superior Warm – Edge seal.

Stainless Steel Spacer
This is a warm edge spacer. This spacer will reduce condensation, heat loss, and provide clean, graceful lines and aesthetically provide an appealing appearance. Because it is made from low conductive steel, it provides natural structural strength in your window. Additionally, because it is steel, it is the perfect barrier preventing moisture penetration or gas leakage.
