“We want all our customers to have this level of peace of mind and it is our intention to conduct fire testing from both sides on all the products in the Profab range. Testing on the 1000 Series access panels is already under way.” Warrington Fire, now a part of the Element Group, is a UKAS accredited laboratory which specialises in fire resistance testing for passive fire protection products. The testing process is stringent, from start to finish. The testing personnel from Warrington Fire come to the Profab Access manufacturing facility to personally select the riser doors they wish to test. Both the doors and frames are signed by the testers to ensure the correct products are delivered to them for testing. Once at the laboratory the riser doors are tested to BS EN 1634- 1:2014+A1:2018, the standard for fire resistance and smoke control. The testing process involves the riser doors being held in a rig in front of a kiln. The size of the rig, 3 metres high by 3 metres wide, enables testing of single, double or triple riser doors to be carried out. The riser doors are tested to measure the integrity of the door and frame when subjected to fire. The process involves ensuring that flaming cannot occur on the unexposed face of the door for longer than 10 seconds and that a 25 mm rod cannot be passed through the specimen. The transfer of radiant heat though the surface of the doors is also measured. Limiting the transmission of heat from one side of the door to the other to protect building occupants so they can safely exit the building is paramount. Amendments have already been made to the Building Regulations Approved Document B (Fire Safety), notably the ban on combustible cladding on all new buildings over 18 metres in height. Further changes are expected as a result of the call for evidence for the technical review of Approved Document B, which closed in March. By taking the lead in fire testing both sides of the 4000 Series riser doors Profab Access is future proofing the products being used in the construction sector. When it comes to riser doors building professionals now have the opportunity to specify products that exceed the legal requirements.
