When door manufacturer DoorCo set out to develop a high-performance fire door system that could deliver consistent performance across a wide range of designs and configurations, they knew it would take technical rigour, robust testing, and the right partners.
Norseal collaborated with DoorCo and Winkhaus UK to develop the new FiRECORE fire door range. With fire, smoke, and security performance at its core, FiRECORE is now fully tested to EN 1634 and available for both internal and external applications.
As specialists in fire, smoke and acoustic sealing, Norseal supported the project with advice, technical input and high-performance sealing solutions throughout the 18-month development and testing process. The result is a fire door set that performs reliably across multiple configurations, including top lights, side lights and glazed designs, with no compromise on fire safety or aesthetics.
“Norseal’s expertise in sealing was vital to achieving the consistent test results we needed,” explains Ian Glenister, Technical and Sales Manager at DoorCo. “Working with knowledgeable, proactive suppliers was key, and they were instrumental in helping us ensure compliance across every detail of the specification.”
FiRECORE can demonstrate an extensive portfolio of test evidence. The complete door set includes a phenolic foam slab, hardwood subframe, and DoorCo’s signature GRP skins. Norseal’s tested sealing solutions integrate seamlessly into the system, ensuring that FiRECORE meets strict fire, smoke and security standards.
“This kind of collaborative development is where we add real value,” says Norseal’s Simon Sutton. “Our job is to make sure the seals don’t just perform in isolation, but as part of a complete, compliant system. That means working closely with fabricators, hardware manufacturers and door designers from the earliest stages.”
