A guide to popular Masonite doors

Here are some popular Masonite doors you may want to consider: 

  • Solid core interior doors: Our solid core interior doors have 70% more sound dampening material than our hollow core doors. This means you can create quieter spaces that work for everyone, especially in bedrooms, bathrooms, home offices and any other room where you want to keep sound in or out. Plus, solid core doors have a substantial, high-quality feel to them. 
  • Masonite Performance Door System exterior fiberglass doors: Every Masonite exterior fiberglass door with our 4-Point Performance Seal is 64% better at keeping air and water out than the leading competitor, resulting in superior energy efficiency, performance and comfort. This front door keeps the outside out and the inside in, meaning you won’t lose precious inside air from insufficient seals or allow hot or cold air to come inside.
  • VistaGrande Flush-Glazed Full Lite and 3/4 Lite exterior fiberglass doors: VistaGrande flush-glazed doors allow up to 18% more light than doors with traditional glass frames, helping to brighten up your interior entryway and enhance your curb appeal. These doors are available as part of the Masonite Performance Door System line.
  • Barn door kits: Whether you need a sliding door for a tight spot or a style upgrade, interior barn doors are an easy DIY solution that can be used throughout the home. Our curated selection of classic options, modern alternatives and everything in between means you can find a barn door that fits your personal taste and style. The best part is the Masonite barn door kits are a great DIY project that can be completed in about 90 minutes.
