Safire® Intumescent Fire Strip is a soft, extruded linear gap seal for use in conjunction with soffit head details or other situations where a small gap requires fire sealing. When exposed to flames and heat, Safire® Fire Strip undergoes controlled expansion or intumescence, reacting to form a carbonised foam. This char resists the passage of smoke and flames and helps to insulate the metal channel beneath.
Supplied in rolls 25m x 25mm x 1.3mm strip depth.
Safire Intumescent Fire Strip has been tested to provide upto 120 minutes fire reistance in accordance with BS476 Part 22: 1987.
Useage Conditions & Storage
Safire Intumescent Fire Strip is unsuitable for use in areas subject to continuously damp or humid conditions and must not be used to isolate dampness. Not suitable for use in temperatures above 49ºC, but can be subjected to freezing conditions without risk of damage.
Store in frost-free conditions between 5ºC – 30ºC. If stored correctly has a shelf life of 12 months.
Ensure that light gauge metal channels and soffits are clean. without stretching it, unreel the self-adhesive strip and apply one strand along the whole length of the metal channel or head plate, then remove the release paper. ensure that the seal is maintained wherever one strand meets another, normally at the channel/head plate ends. Safire Fire Strip can also be used to seal small gaps in other situations.
