Since 1973, Coastal Industries, Inc. has operated an advanced 50,000-square-foot manufacturing plant at 77 Newark Street, Haverhill, MA. Built specifically for high-capacity custom fabrication, our facility serves international B2B distributors, commercial building contractors, and regional construction leaders seeking precision-engineered fenestration products.
Every window, sliding door, storm unit, and architectural enclosure is fabricated to order. By utilizing heavy-duty multi-chambered vinyl profiles and automated assembly systems, we maintain complete control over dimensional accuracy, structural integrity, and thermal performance standards.
Micron-accurate automated welding and corner cleaning operations.
Dual-seal insulated glass fabrication with Argon gas injection.
Industrial-grade vinyl engineered for long-term structural endurance.
Fabricated exact to project specification down to 1/8-inch tolerances.
Our facility integrates European automated machinery with rigorous quality assurance protocols to output architectural-grade window and door systems.
Utilizing the industry-leading Rotox SMH510 four-point welder, our vinyl profiles undergo simultaneous fusion welding at precise temperatures, creating seamless, leak-proof frame corners with superior structural load capacities.
High-precision Rotox CNC corner cleaners automatically profile and polish welded frame joints, delivering immaculate surface finishes while maintaining tight tolerances for multi-cavity weather-stripping installation.
Our vinyl profiles feature multi-chambered internal geometry that prevents thermal transfer. Heavy wall thickness ensures optimal screw retention, wind-load performance, and resistance to severe climate cycling.
Energy conservation in structural fenestration relies heavily on advanced glass technology. We assemble high-performance Insulated Glass Units in-house to satisfy global energy standards.
Insulated Glass Units (IGUs) create a thermal barrier by separating two or more glass panes with a sealed gas-filled chamber. This configuration dramatically impedes radiant heat transfer, reducing overall solar heat gain coefficient (SHGC) and U-factor values for commercial and residential applications.
Our glass line applies microscopic Low-Emissivity (Low-E) metal coatings that reflect long-wave infrared energy. During winter, interior ambient heat is reflected back inside; during summer, external solar heat is deflected away. Sealed with high-density warm-edge spacers and inert Argon gas, our IGUs deliver continuous thermal efficiency and UV protection.
