Proven reliability and safety you can trust.
A patented and NRTL-listed composite temperature
rise door core for use with steel fire doors.
Temperature rise steel door manufacturers consistently choose tempRCORE for its proven test standard success (UL 10C, UL 1784), superior surface adhesion and mechanical strength.
Fire-Rated steel doors play a vital role in ensuring a fire safe route for up to three hours.
tempRCORE delivers durability and strength with its inorganic composite core wrapped in woven fiberglass. The patented design delivers a powerful fire barrier for both single and standard double steel doors.
The 55 lb. tempRCORE is a mineral temperature rise core approved by Warnock Hersey and UL for 1.5 and 3 hour positive and negative pressure steel doors, UBC 7-2, NFPA 252, UL 1OC, ULC CAN4-S104-M80, for single doors up to 4′ x 8′ and standard double doors up to 8′ x 8′. Warnock Hersey has approved the core for 1.5 hour positive and negative pressure for double egress up to 8′ x 8′.

temprCORE is a patented inorganic based composite core, a large component of which is polystyrene.
The core is Approved by Warnock Hersey and UL for 1.5 and 3-hour positive pressure (including negative pressure) steel doors, UBC 7-2, NFPA 252, UL10C, ULC CAN4-S104-M80, for single doors up to 4’ x 8’ and standard double doors up to 8’ x 8’.Warnock Hersey has approved the core for 1.5 hour positive and negative pressure for double egress up to 8’ x 8’.
The core is currently available commercially in dimensions 33.5” x 74.5” – 80” H x 1.656”D but could be made to other dimensions if desired.
The door, core and wall assembly must match what is listed. The door must be the proper steel gauge and assembly of wall construction must match what was used in the testing.
No information on R rating at all. Although we believe it is insulative and STC is based on the door assembly as it would be mounted, we don’t test for this. The rest of the answers are on the PDS or sales sheet.
