Product Overview
Mineral core fire-rated wood doors for commercial and institutional applications
Architectural grade wood fire doors control the spread of fire and smoke for up to 1-1/2 hours (90 minutes). Fire doors are often used on openings leading from corridors to offices, closets, storage rooms, stairwells, mechanical rooms, or any other opening that penetrates a fire barrier wall.
Flush mineral core construction is a bonded and sanded gypsum core. Fire doors are required to be self-closing and positive latching. The door frame and hardware must also carry the appropriate fire label. Metal Doors must be used for 3 Hour Fire-Rating.

Wood is a natural material with inherent growth patterns. The uniqueness offered by wood makes it appealing and interesting in the realm of design and beauty. This same uniqueness, along with variations caused by screen color and resolution, is why actual colors and door face veneers may vary from what is pictured here.
*Rotary Natural Birch veneer displays fine wood texture and a very irregular grain pattern that is accentuated by the presence of light-colored sapwood permeated by much darker heartwood. The extreme difference in coloration may be highlighted or subdued when the door face veneer is finished and should, therefore, be considered before specifying Natural Birch. Machined wood doors are non-returnable.
