Stairwell Doors, Temperature Rise Fire Doors

All Temperature rise doors exceed the fire code limits by using special construction that allows us to achieve a 450 degree for 30 minutes maximum temperature rise rating on our Syntégra™ Door System.

As with all our doors, the Stairwell Temperature Rise door has the lowest smoke leakage rating in the industry, comes in a variety of low profile hardware, and installs in a matter of minutes.

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.
