Operating since 1973, Coastal Industries, Inc. delivers factory-direct architectural windows, vinyl sliding doors, light commercial aluminum systems, and custom porch enclosures. We engineer products to exact technical specifications for both North American construction projects and overseas commercial importers.
Every unit is manufactured to order in 1/8-inch increments. We accommodate complex architectural geometries, custom sightlines, specialized thermal packages, and unique profile requirements with zero reliance on outsourced assemblers.
Our glazing options incorporate multi-chambered fusion-welded frames, dual or triple-pane Low-E glass, argon gas thermal insulation, and warm-edge spacer systems engineered to withstand severe climate environments and strict international building codes.
We serve commercial developers, general contractors, and independent overseas distributors. Orders are secured with export-compliant ocean-freight packaging, standardized unit schedules, and streamlined factory lead times.
Whether you require regional installation services in New England or full containerload OEM shipments overseas, Coastal Industries provides an integrated, accountable manufacturing pipeline.

Key information for commercial buyers, international sourcing agents, and general contractors.
Yes. We work directly with international project managers, trade distributors, and commercial procurement teams to produce customized production runs, offering full technical drawings, sample verification, and export packaging for container shipping.
Our core production lines include vinyl double hung, single hung, casement, awning, and fixed picture windows; vinyl patio sliding doors; light commercial aluminum double hung and sliding windows; storm window and door systems; and custom three-season porch enclosure panels.
Because all profiling, fusion welding, glass cutting, and unit assembly take place under one roof in our Haverhill plant, custom shapes—including arch tops, trapezoids, bay and bow configurations, and radius units—are fabricated to exact field measurements with standard mill lead times.
We source heavy-duty extruded vinyl and aluminum alloys paired with certified insulated glass units. Dual-seal warm-edge technology and argon gas fill options ensure compliance with high thermal efficiency standards and rigorous structural weather-resistance requirements.
