      Frequently Asked Questions

      What Masonite door styles are available at Windsor Plywood?
      Windsor Plywood carries Masonite interior panel doors in 2-panel, 4-panel, 6-panel, and arch-top configurations, as well as flush and moulded panel styles. Exterior Masonite doors include fiberglass and steel entry door systems. French door and bifold configurations are also available in the Masonite line.
      Are Masonite fiberglass doors energy-efficient?
      Yes. Masonite fiberglass exterior door systems are engineered for energy performance with factory-applied weatherstripping and thermally broken frames in insulated door slab constructions. Fiberglass resists the temperature-related expansion and contraction that causes drafts in steel and wood door systems over time, maintaining a tighter seal through Canadian seasonal extremes.
      Can Masonite doors be painted or stained?
      Masonite smooth moulded panel doors are designed for painting and provide a clean, grain-free surface for a professional painted finish. Masonite hardwood and wood species doors accept stain. The Hemlock Shaker and Knotty Alder lines are specifically designed for stained natural finishes where the wood character is the design intent.
      What is the Masonite Fast-Fit installation system?
      Masonite Fast-Fit is a pre-assembled door package that includes the door, jamb, casing, and all hardware in a single unit designed for simplified installation. The system significantly reduces on-site installation time compared to assembling individual components. It is particularly useful for production renovation projects where multiple doors are being installed.
      What warranty does Masonite provide on their doors?
      Masonite offers a limited lifetime warranty on interior doors against manufacturing defects. Exterior door systems carry a limited warranty on the door slab and separate warranties on glass and finish components. Specific warranty terms vary by product line. Windsor Plywood staff can provide current warranty details for the specific Masonite products you are considering.
