Flue Sealants (1)
Our crack and heat-resistant flue sealants are used to seal joints in domestic gas flues and are available in 1kg tubs. These sealants can either be paste, silicone or compound. The silicone sealer is non-flammable and can withstand the repeated temperatures of a domestic gas flue. The compound is easy to work into gaps and joints and does not harden, allowing small movements without cracking.
