Not all riser doors are fire tested equally . Ensure legal compliance with bi-directional testing
Our renowned 4000 Series riser doors have always been specified by architects for delivering the highest standards in third party fire certification without compromising on architectural design .
Unlike the rest of the industry , we fire test our riser doors from both sides to ensure legal compliance and still achieve 240 minutes certified fire rated performance .
Given the choice , why would you specify anything less ?
