Durable, versatile, and low-maintenance, our fibreglass products offer a smart solution for modern home builds and renovations. Commonly used in exterior doors, fibreglass is known for its superior resistance to warping, cracking, and weathering—making it ideal for withstanding Canada’s diverse climate conditions. Our fibreglass doors are designed to mimic the look and texture of real wood while providing enhanced insulation, energy efficiency, and long-lasting performance. Whether you're looking for a sleek, modern design or a traditional woodgrain finish, we carry a range of styles to suit your home’s aesthetic and budget. Windsor Plywood is proud to offer high-quality, hard-to-source building materials with a focus on outstanding value and personalized service. With over 60 locations across Western and Central Canada and the Northwestern US, we’re here to help you choose the right fibreglass products to bring your vision to life.
Windsor Plywood carries Masonite interior and exterior doors. Masonite is one of the largest door manufacturers in North America, offering a broad range of products including interior moulded panel, flush, and glass-lite doors, as well as exterior fiberglass, steel, and wood entry door systems. Both hollow core and solid core interior options are available, along with pre-hung exterior door systems.
Masonite interior doors include traditional 6-panel colonial, 2-panel, shaker flat panel, and glass-lite configurations in hollow and solid core. Their Smooth series provides a clean, primed surface ready for painting. Masonite also produces pre-hung interior door systems with adjustable frames for standard wall thicknesses.
Masonite exterior door systems include ENERGY STAR qualified options with polyurethane foam core insulation, thermally broken composite frames, and multi-seal weatherstripping designed for Canadian climate conditions. Their Fiberglas Pro series provides high thermal performance suitable for Canadian residential new construction and replacement applications.
Masonite offers a limited lifetime warranty on interior door slabs and exterior fiberglass door slabs against manufacturing defects under normal residential use. Exterior steel door slabs carry a limited warranty of shorter duration. Glass and finish components are covered by separate, shorter warranties. Specific terms vary by product line and require warranty registration after purchase.

Non-standard sizes, specialty glass configurations, and less common profiles are available through special order with extended lead times.
