High Temperature Sealants Beat the Heat

Heat resistant sealant is used for a wide range of applications where withstanding high temperatures is paramount. While fire resistant walls, partitions and other structures are skilfully designed to prevent fire and heat damage, they are only as effective as the sealant that bonds them together.

All heat resistant sealants come with a detailed set of fire rating regulations. These regulations may seem like gobbledegook at first, but they have great significance. Everflex Fire Mate, for example, is a five hour rated, intumescent sealant tested following the principles of BS EN 1366-4:2006 as detailed in Warrington Fire Research Report No. 181967 (May 2009). Acoustic rated to BS EN ISO 140/3. Tested for air permeability to EN13141-1.

This basically translates as: “It will resist the passage of fire for 5 hours, swelling up with the heat to secure and seal any gaps in the event of a fire. This firm yet flexible sealant can be used in a variety of fire rated structures, and it also acts as an acoustic sealant.”

There are a variety of heat resistant sealants, each with their own specialist properties. Some are extra-adhesive, some are suited for external use, some are designed to secure electrical equipment… but the thing they have in common is their amazing heat and fire resistant properties.
