A Message From Our Sponsor

At MASTERGRAIN™, every part of our door system is engineered with durability in mind. From the slab to the cladded components, it's all fiberglass – offering superior stability and resistance to warping or rot, reducing callbacks and ensuring long-term satisfaction for your clients.

Proudly designed and manufactured in Canada, we use advanced Nickel Vapour Deposition (NVD) technology to create the most realistic woodgrain textures with the strength to withstand harsh weather conditions.

Why MASTERGRAIN:
  • Choose from six stunning woodgrain or smooth finishes to suit any architectural style
  • Built in Canada to withstand extreme weather—resists warping, rotting, rusting and denting year after year
  • A high-density polyurethane core keeps your home comfortable and energy costs down in every season
  • Door slabs and components are crafted from fiberglass for a seamless finish
