Sometimes called "passage doors" (indicating passage between interior rooms or into closets), wood interior doors add natural beauty and warmth to the home. Custom interior doors are manufactured with slightly different construction than exterior doors, and do not have the same pre-finishes or security requirements. For example, interior doors are made with engineered lock and kick rails, while these rails are solid wood on exterior doors to resist delamination when exposed to outside elements. Finishes for interior doors do not have a topcoat to protect against rain and Ultra-Violet (UV) light, and are thus less expensive than wood finishes for exterior doors.
