CRL Edgetech Super Spacer® 1/4 in Gray Insulating Spacer - 66 ft Roll

• Allows simultaneous production of regular and special-shaped insulating glass units (curved, odd-shaped)
• Save production time — no desiccant beads to add or corner keys to assemble
• Available in gray or black
• No head compression required
• Multi-layer vapor barrier is continuous at corners to reduce moisture and inert gas loss

CRL Edgetech Super Spacer® (SKU: SS1466) is a premium silicone foam spacer for insulating glass that substantially reduces perimeter edge condensation and overall window heat loss. Its flexible, UV-resistant silicone foam accommodates glass bowing and thermal movement—making it ideal for curved and odd-shaped insulating glass units, sound-insulating applications, and triple-glazed units with art glass inserts. The spacer’s multi-layer barrier film minimizes moisture vapor transmission and inert gas loss, while the foam’s permeability allows fast initial moisture pick-up during fabrication.

Rolls are 66' (20.1 m) long. Other colors and bulk rolls available on special order.

Installation note: Super Spacer® must be used with an edge sealant. We recommend CRL Hot Melt Butyl or CRL 877 Super Spacer® Sealant.

Product Warning:

Always wear proper protective safety gear when handling glass.
