MDF Interior Door Designs

Sun Mountain’s MDF doors are high-quality—true stile and rail construction with engineered components made with Timberstrand® LSL core, sandwiched by 1/8″ thick MDF veneers and solid Poplar edge caps (for hinge mounting). This superior design is resistant to warp.

The product is pre-primed at the factory, with optional solid Poplar primed jambs. The company ships pre-hung units nationwide, direct to the home or jobsite.
