Interior Wood Doors

Frequently Asked Questions

What's the difference between an interior panel door and a flush door?

Panel doors feature raised or flat geometric panels framed by stiles and rails — the classic look you see in Craftsman, Traditional, and Shaker styles. Flush doors have a smooth, flat face, which lends itself to contemporary and modern interiors. Both are available in a wide range of wood species and sizes at Simpson, so the choice comes down to the architectural style of your home and the look you're going for room by room.

Can I match my interior doors to my exterior front door?

Yes — and it's one of the most cohesive design moves you can make. Simpson can build any interior door in the same design, wood species, and finish as your exterior door. Any exterior door design can also be adapted for interior use. If you're designing a full project from scratch, this is worth discussing with your dealer early so everything is specified and ordered together.

What is a Redi-Prime^® door and when does it make sense?

Redi-Prime^® doors come pre-primed from the factory, making them ready to paint. They're a practical choice when you want a consistent painted finish across multiple rooms — closets, hallways, bedrooms — and want to save time on finishing. They're available in a full range of panel designs and standard sizes.

What interior door applications does Simpson offer beyond a standard passage door?

Quite a few. Simpson builds interior doors in the following configurations: passage (standard hinged), French (pairs with glass), bifold (for closets and wide openings), barn/bypass (surface-mounted or bypass track), pocket (disappears into the wall), and pivot. Each application has different framing requirements and hardware considerations — your dealer or contractor can help you match the right application to the opening.
