Abstract
Abstract A silicone slab for use in a building curtain wall to seal the joints between adjacent support members in the curtain wall. The curtain members define a U-shaped channel for support of the curtain wall material. Adjacent ends of the support members are sealed by placing a silicone slab in the joint bridging the two support members. The silicone slab is retained in place by a silicone sealant.
