FORMERLY MCKINNEY DOOR SOLUTIONS & AMERICAN DOOR PRODUCTS - NOW UNITED AS AMERICAN DOORS.
A flush door with a core constructed from laminated veneer lumber (LVL) or laminated strand lumber (LSL), providing exceptional strength and dimensional stability. Laminated cores are specified for heavy-duty and oversized doors.
Laminated cores consist of wood veneers or strands bonded under pressure with adhesive, creating engineered lumber stronger than solid wood. Cores provide excellent screw-holding for hardware and resist warping in changing humidity.
Fire-rated laminated core doors achieve ratings through the core material itself or additional intumescent layers. Applications include oversized doors, high-abuse areas, and doors requiring extra hardware reinforcement. Related: solid-core door, flush door. Shop heavy-duty doors.
