LaHouse - Windows and Doors

Windows are selected and sized to meet code-specified “design pressure rating” (DP) for a 130-mph wind zone. In the SIPS area, windows and doors are no taller than standard 6-foot, 8-inch height. Larger openings could require additional strengthening measures. Impact-rated shutters (Bahama, colonial, roll-up, accordion), panels and screens will protect windows and doors that are not impact-rated. Windows and doors without external protections are designed as impact units. Stained glass is shielded by a layer of impact glass.


Windows and doors are flashed to drain water outward. Sill flashings are rigid or flexible, include corner protection, and have back-dams or slope outward. Flashings are integrated shingle-fashion with the housewrap to maintain a continuous drainage plane. Seams of foil-faced OSB are taped to provide a moisture barrier, vapor barrier and drainage plane all in one.
