The National Fire Research Laboratory

National Fire Research Laboratory Interior

The National Fire Research Laboratory (NFRL) is a unique experimental facility dedicated understanding fire behavior and structural response to fire. The laboratory offers approximately 3000 m2 of testing space constructed around four exhaust hoods (1 MW, 3 MW, 10 MW and 20 MW). The facility has a strong-floor and strong-wall to allow for controlled structural loading underneath the 20 MW exhaust hood.

For additional details and project information please visit the main NFRL homepage.
