Precision Architectural Fenestration

Architectural, Garden, Bay & Bow Windows

Custom-engineered radius vinyl shapes, DP50-rated greenhouse garden windows, and heavy-duty structural bay and bow assemblies for commercial contractors, distributors, and custom builders.

Engineering Precision

Custom Architectural Fenestration for Global Procurement

Coastal Industries combines over 50 years of North American manufacturing discipline with advanced vinyl extrusion bending technology. By bending over 600 custom profiles to millimeter tolerances, we supply commercial developments, multi-family construction, and high-end residential projects with high-integrity architectural glass systems.

Architectural Geometric Shapes

Custom radius bending accommodating true circles, arch-tops, trapezoids, ellipticals, and custom cathedrals. Designed to allow field-glazing or pre-cut IG unit integration with airtight fusion welds.

  • Over 600 vinyl profile variations
  • Radius precision to CAD templates
  • Reinforced multi-chamber walls

Engineered Garden Windows

Greenhouse window systems featuring DP50 structural ratings, multi-point water deflection tracks, twin operable trapezoid side lites, and insulated composite thermal seat boards.

  • Design Pressure up to DP50 rating
  • Available coastal impact certification
  • Sloped roof tempered glass panels

Structural Bay & Bow Assemblies

Engineered multi-lite projection systems fabricated with oak or birch structural timber framework, aluminum mullion reinforcement, and integrated tie-rod cable suspension systems.

  • 30°, 45° Bay & 90° Box Bay setups
  • 4 to 6 panel sweeping Bow designs
  • Compatible with Casement/Double-Hung
Custom Extrusions

Custom Bending: Arch Tops, Eyebrows & Polygons

Standard fenestration limits bold architecture. Coastal Industries utilizes high-precision automated thermal bending equipment to calibrate vinyl profiles to strict curvature radiuses without structural buckling, discoloration, or seal impairment.

Whether matching existing historic restoration masonry openings or fabricating complex geometric facades for light commercial complexes, our components deliver verified structural performance and uniform thermal resistance across all joints.

Structural Garden Series

Engineered Greenhouse Garden Windows

Our Series 2050 garden units are engineered specifically for demanding climates, providing deep interior display space combined with strict air and water infiltration barriers. Featuring heavy-duty insulated 1-1/4" furniture-grade seat boards wrapped in exterior acrylic finishes, these units resist rot, moisture ingress, and thermal conduction.

Each unit features a tempered glass sloped roof that sheds snow and water effortlessly, while dual side-venting lites equipped with heavy-duty stainless steel operators provide controlled cross-ventilation.

Projection Window Systems

Bays, Bows & 90-Degree Box Bay Configurations

Projection windows demand exceptional engineering to prevent sagging, structural deflection, and air leakage over decades of use. Coastal Industries bay and bow windows are built utilizing structural furniture-grade oak or birch head and seat boards, sealed with multi-stage polyurethane weather barriers.

Configured using commercial-grade Double Hung, Casement, or Picture window modules, these units create spacious panoramas while preserving rigorous energy envelope requirements. Internal steel tie-rod cable systems anchor the assembly directly to the building framing, eliminating the need for unsightly external corner brackets.
