All Temperature rise doors by Total Door exceed the fire code limits by using special construction that allows us to achieve a 250 degree for 30 minutes maximum temperature rise rating on our door system.
As with all Total Doors, the Stairwell Temperature Rise door has the lowest smoke leakage rating in the industry, has been tested for 5 million cycles, comes in a variety of low profile hardware, and installs in a matter of minutes.
Total Door Temperature Rise Doors come with either 90-minute or 180-minute positive pressure fire labels. Built-in electronic locking functions for security purposes are optional as well.
