      Frequently Asked Questions

      What interior door styles does Windsor Plywood carry?
      Windsor Plywood carries interior doors in panel, flush, French, bifold, and pocket door configurations from brands including Masonite, Jeld-Wen, and Trimlite. Panel doors range from traditional 6-panel colonial to contemporary flat-panel shaker styles. Both hollow core and solid core constructions are available in standard and custom sizes.
      What is the difference between hollow core and solid core interior doors?
      Hollow core doors use a cardboard honeycomb fill between two thin face skins. They are lightweight and cost-effective, suited for closets and low-traffic rooms. Solid core doors use a dense wood composite fill that significantly improves sound attenuation and gives the door a heavier, more substantial feel. Solid core is the better choice for bedrooms, home offices, and bathrooms where noise reduction matters.
      How do I determine the correct door swing for my room?
      Stand in the door opening facing the room you are entering. If the hinges are on your right, it is a right-hand door. If the hinges are on your left, it is a left-hand door. For pre-hung doors, the swing direction is set at the factory, so confirming this before ordering avoids having to return the unit.
      What wood species are available for interior doors at Windsor Plywood?
      Interior wood doors are available in hemlock, maple, red oak, white oak, alder, pine, poplar, cherry, and MDF, depending on the manufacturer and door style. MDF doors provide the smoothest painted finish. Stained applications benefit from species like oak, alder, and maple where grain character is part of the design intent.
      Do interior doors come pre-drilled for hardware?
      Most interior slab doors come pre-bored with a 2-1/8 inch diameter bore for the lockset and a 1 inch diameter bore for the latch, with a standard backset. Pre-hung doors include the bore as part of the package. If you are purchasing a slab door to fit an existing frame, confirm the bore location matches your existing hardware before purchasing.
