Choosing Windows and Doors for a Coastal Home
Wind, salt air, sun, and water: what to plan for near the coast.
Start with your code requirements
Coastal areas often call for higher wind-load performance, and some locations require impact-resistant glazing or approved opening protection. Requirements vary by address. Confirm them with your local building department, architect, or engineer before selecting products.
Ratings to ask about
Design pressure (DP): how the product performs under wind load.
Impact resistance, where your location requires it.
Energy performance: U-factor and solar heat gain coefficient (SHGC).
Ask for documentation for the exact product and size you're ordering, not just the product line.
Plan for salt air
Ask about the frame finish specification and hardware options for coastal exposure. Plan on periodic rinsing and maintenance, and keep the care instructions with the house documents.
Glass for heat and glare
Low-E coatings help control heat gain. On large west-facing glass, look closely at SHGC, and plan shading as part of the opening rather than an afterthought.
Large openings need real details
Sill design and drainage for sliding and bi-fold doors.
Threshold height versus water management at exposed doors.
Headers and structure sized for wide spans.
