Fire Rated Doors

Fire Rated Doors require special materials and sealing to provide damage security when needed.  In applications where fire is a threat the capabilities of fire rated doors can keep fire and smoke out of other occupied areas of the building to minimize risk of more extensive damage.

Whether it’s an industrial or commercial application fire risk can be a concern for safety of human life. Preparing for emergencies with fire doors is an excellent way to slow the spread of fire, potentially saving lives.

Industrial applications that generate smoke or fumes can also be tamed with fire rated doors to minimize discomfort for employees.  The added insulation and sealing of a fire door can improve working condition in many manufacturing environments by minimizing odors, fumes, or heat transfer between building areas. Doors can also be triggered to automatically shut in the presence of  extreme heat or the slightest detection of smoke with motorized operation and sensing equipment.

REG 4 Testing

Many counties require regular fire door testing to REG 4 standards.  Commercial Door Company is certified to provide REG 4 testing and certification for commercial buildings in California.  If you need certification call us to arrange your inspection and testing to be performed.


Door manufacturers have regulatory testing to be certified as “fire worthy” for certain lengths of time and different types of fires.  NFPA 80 rated doors are often required in commercial buildings for safety requirements.  CDC sells and installs a variety of NFPA 80 rated doors, and we are certified for the installation and testing of fire doors in California.
