Fire Rated Doors

Cease fire

Solid mineral cores impede the path of the flame to buy time and save lives. Trust Oshkosh Door Company with your fire rated specifications.

These interior wood doors are available with fire ratings of 45, 60, or 90 minutes in a wide variety of hardwood, medium density overlay, and laminate faces. Our fire rated doors meet WDMA extra heavy duty performance level standards with appropriate blocking. Without blocking, the doors will meet standard duty performance level.
