CRL Edgetech Super Spacer® is made from superior insulating silicone foam. The spacer essentially eliminates perimeter edge condensation and substantially reduces overall window heat loss. Because of the unique design features of Super Spacer® there are advantages in using this product for the fabrication of specialized insulating glass designs, including curved and odd shaped units, sound insulating, and triple-glazed units with art glass inserts.
For long-term durability, UV resistant silicone material is used to prevent spacer degradation. The flexible foam spacer provides friendly accommodation of glass bowing and thermal movement, and also helps ensure improved edge seal desiccant, and the permeability of the foam allows for fast moisture pick-up. To reduce moisture vapor transmission and inert gas loss, the Super Spacer® is backed by a high performance, multi-layer barrier film.
Rolls are 66' (20.1 m) long. Other colors and bulk rolls are available on special order. NOTE: Super Spacer® cannot be used without an edge sealant. We recommend CRL Hot Melt Butyl or CRL 877 Super Spacer® Sealant. Important Notes: Always wear the proper protective safety gear when working with and handling glass.
