摘要:
A single or double glazing panel is received in a groove in a wood sash frame. The glazing panel carries on it a bead of butyl sealant along the exterior face adjacent the peripheral edge while a bead of silicone adhesive is placed on the peripheral edge or in the bottom of the groove. Insertion of the panel into the groove causes the sealant to roll and flow along the exterior wall of the groove and along the exterior face of the glazing panel such that no cleanup after assembly is required. Adhesive is prevented from contacting viewable areas of the glazing thereby avoiding cleanup. Cladding may be placed over the exterior of the wood sash frame covering the sealant and space in which it is contained.
