The CastleGate exterior door system features a large selection of Masonite fiberglass doors and glass designs to suit any style.

  • Insulated Glass & Warm-Edge Spacers reduce energy costs and prevents condensation.
  • Polyurethane Core insulates 5x better than real wood to keep homes cool in the summer and warm in the winter.
  • Fiberglass Skin resists warping and rotting and protects against rust and dents.
  • Composite Bottom Rail provides rot resistance.

Weather Resistance Proven to Perform

In a certified test by a third party*, the CastleGate Exterior Door Systems by BWI lasted significantly longer in more extreme weather conditions than the market-leading competitor, which failed to perform in moderate conditions.

*Door systems were exposed to 8″ of rainfall per hour and windspeeds corresponding with the DP (Design Pressure) Ratings in 23-minute long trials. Certified test performed by Architectural Testing, Inc., an Intertek Company.
