Temperature Rise Rated Door
Temperature Rise Rated Door offers exceptional Insulation to temperature [during a Fire] which makes it extremely suitable for enclosed areas such as Exit Stairwells, Exit Enclosures and Corridors. These Doors are specifically designed for enclosed openings [eg. Stairwells] which require conformance to NFPA 80 (or) similar fire protection recommendation for maximum temperature rise requirements.
Temperature Rise rated can limit the transmission of heat for a period of time so that people can safely move to the lower floors thereby exiting the burning building. These doors are built with a leaf Infill that is specifically designed to restrict the transmission of heat.
