Molded Hollow Core Doors

Hollow Core molded doors offer a lighter-weight, economic alternative to wood stile and rail interior doors.


Molded Doors are constructed as two skins separated with lightweight materials in the middle. The skin, or face, of the door is a 1/8” molded hardboard skin that is available with a smooth or textured painting surface.

In between the skins is a hollow core which includes blocking. This provides support for the door skins, but does not provide any sound insulation.

Stiles and Rails

Along the vertical edges of the doors are wood or MDF stiles. Hollow core doors are available with medium density fiberboard (MDF) stiles as the lowest cost option. Wood stiles are preferred for better durability and strength. Along the top is a single fiber rail. Doors with wood stile have either a double or triple bottom rail depending on the height; doors with fiber stiles will have a single fiber rail. The benefit of a double or triple bottom rail is it can be field trimmed.
