• Multi-layer vapor barrier is continuous at corners for reduced moisture ingress

CRL Edgetech Super Spacer® (SKU: SS316916) is a premium insulating silicone foam spacer for insulating glass units. The flexible silicone foam spacer minimizes perimeter edge condensation, reduces overall window heat loss, and accommodates glass bowing and thermal movement—making it ideal for curved, odd-shaped, sound-insulating, and triple-glazed units with art glass inserts.

Long-term UV-resistant silicone prevents spacer degradation. The foam's permeability allows fast moisture pick-up, while a high-performance, multi-layer barrier film reduces moisture vapor transmission and inert gas loss. Rolls are 66" (20.1 m) long; other colors and bulk rolls available by special order.

Important: Super Spacer® cannot be used without an edge sealant. We recommend CRL Hot Melt Butyl or CRL 877 Super Spacer Sealant.

Product Warning:
Always wear proper protective safety gear when working with and handling glass.
