The quality of raw materials specification matters…as does the skill to accurately weld them to fabricate our distinctive red, heavy-duty RSA flanges which are an integral component of CASWELL FIRESAFE® EN fire resisting ductwork.

CASWELL FIRESAFE® is manufactured at our Haslingden, Lancashire facility to EN 1366-1 & 8; or, alternatively, to BS 476-24 where the required dimensions are outside the scope of these EN Standards.

It is available in tiered service packages starting with ‘supply only’ right through to a full supply, install and certification package – with or without insulation.

Whatever the project demands, CASWELL FIRESAFE® is up to the job and Clients entrust us to meet their building’s passive fire protection needs.
