Unprotected cavities around fire-door frames and partitions can be easily exploited by fire which can undermine the fire performance of the door if not sealed correctly.
The new FAS Fire Door Silicone Sealant from Fire and Acoustic Seals has been specifically tested to seal gaps around external and internal 60-minute fire-rated doors, flat entrance doors and external timber screens to meet BS 476: Part 22 1987 & BS EN 1634-1: 2014, and for smoke and air leakage to BS EN 1634-3: 2004.
It has been tested to successfully seal cavities of up to 30mm wide by applying a 10mm deep silicone cap over either mineral fibre wool or FAS’s own-label Fire Door FoamTM.
It also has 240 minutes of fire-test evidence for other applications such as joints in walls, roofing and bead glazing, with the added benefit of resisting general weather elements making it an extremely useful fire-stopping sealant on site.
The recent FAS Fire Door Silicone Sealant 60-minute fire and smoke tests were conducted at the industry-leading Warringtonfire laboratory to seal gaps around the door frame of an FD60 timber doorset.
It was also applied to seal the gap around a customer’s PVC-encapsulated fire door to provide 60 minutes of fire protection. Manufactured by Door Solutions Group, this is currently the only door of its kind to offer this specific FD60 fire-door test evidence to the commercial sector.
The door is wrapped in 2mm thick PVC providing excellent resistance to bacteria, which helps to reduce the spread of disease making it ideal for healthcare and public sector settings.
Donovan Watkins, MD of Door Solutions Group, comments: ‘We’ve bought all our intumescent seals and sealants from Fire and Acoustic Seals for many years including drop seals, fire strips, hinge pads and jackets. We also buy the FAS Fire Door Acrylic Sealant for glazing and sell on the hugely popular FAS Fire Door FoamTM with our doors as they have been fire tested together. This new test evidence will allow us to do the same for the FAS Fire Door Silicone Sealant whilst giving us a fantastic new opportunity for our customisable PVC-encapsulated doors.’
Julian Vollans, MD of Fire and Acoustic Seals, comments: ‘The new FAS Fire Door Silicone Sealant has been developed to provide fire and water repellent qualities that would suit internal and external applications such as FD60 flat entrance doors. The partnership with Door Solutions Group provided the chance to specifically test it with their FD60 PVC doorset and our Fire Door FoamTM to provide additional sales opportunities that can be clearly backed up by test evidence. We hope this product will be as successful as our other ‘Fire Door’ purposely tested range of products – FAS Fire Door Foam TM and FAS Fire Door Acrylic Sealant.’
The new sealant seals joints up to 25mm without slumping and stays elastic with up to 25% movement capability. It has also been fire tested to work with timber or plastic packers and comes in new FAS-branded, fully recyclable cartridges which will be rolled out across other products later this year.
