Cascadia Windows & Doors
Fiberglass windows and doors with Passive House, acoustic, wildfire, and low-carbon performance options.
What they're known for
A single commercial-grade fiberglass frame platform stretched from residential windows to doors and full window-wall systems without falling back to thermally weak aluminum.
Cascadia Windows & Doors manufactures the Universal Series around a pultruded fiberglass frame designed for high thermal and structural performance. Residential configurations include fixed, tilt-turn, casement, awning, hopper, and door systems with double- or triple-glazed units, while certified PHI and Phius options support Passive House work. The same platform now includes wildfire-resistant configurations and a third-party-verified Environmental Product Declaration, giving specifiers unusually broad performance documentation for a fenestration system.
