Product Details

Rotary Natural Birch 60 minute mineral core commercial wood doors are fire rated doors designed to provide up to one hour of fire protection while maintaining the appearance of architectural commercial wood doors. They are constructed with non-combustible mineral cores made from gypsum and fire-resistant materials, reinforced with hardwood stiles and rails, and finished with veneer, HDF, or laminate faces.

These fire rated commercial wood doors are commonly used in office buildings, hospitals, schools, airports, hotels, and government facilities. Typical applications include stairwell doors, mechanical and electrical room doors, service corridors, storage rooms, and fire barrier walls where additional fire protection is required.

60 minute fire rated wood doors help protect exit pathways, critical building systems, and occupied spaces. Compatible with commercial hardware and available with factory finishes, mineral core doors provide code-compliant life safety protection for demanding commercial environments.
