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 pickup. To reduce moisture vapor transmission and inert gas loss, the Super Spacer™ is backed by a high performance, multilayer barrier film. We recommend using CRL 877 Super Spacer Sealant
with this product.
