MDF-DOORS.com is an online retailer of 1-3/4” thick MDF interior doors, made by Sun Mountain—an industry-leading manufacturer of custom wood doors. Here you’ll find the absolute highest quality solid-core MDF doors, priced at the best value.
Our Medium Density Fiberboard (MDF) doors are “made by hands” in the USA at our state-of-the-art factory in northern Colorado. Sun Mountain’s doors are true stile and rail construction (not routed or moulded), with engineered components to resist warp. Choose from a selection of contemporary designs, pre-primed in the factory, with optional finger-joint Pine jambs. We sell direct to the trade or homeowner and ship nationwide to your home or construction site.
