About this detail

An Efco fixed window unit is mounted above a pressure-treated wood sill plate that rests on a concrete foundation with an intervening EPDM sill plate gasket and vapor retarder. The window head assembly is secured using typical hot-dipped galvanized sill anchors with countersunk fasteners and manufacturer-specified clip anchors, with sealant, backer rod, and shims applied at the joints. A metal drip and flashing assembly extends outward with a four-inch minimum slope away from the glazing. Interior finishes include Marmoleum flooring over felt expansion joints and insulation, a hydronics system embedded in the floor assembly, and a wood base with a roller shade guide visible beyond.
