Why Choose Us ?

FIRESAFE FIRE RATED DUCTWORK Limited are specialists in fire resisting ductwork.
There are a number of key success factors that make our non-coated, fire resisting ductwork stand out from the market competition.

We believe the following make a compelling case for selecting us as your supplier of choice:

  • Market-leading CASWELL FIRESAFE® product 
  • Peerless customer support 
  • Dedicated staff with in-depth technical knowledge and solutions expertise
  • International experience


CASWELL FIRESAFE® is a range of non-coated fire resisting ductwork products.
It is a market leader in establishing this distinct product category on the International stage and is fully tested and certified to the most stringent regional, country and ISO standards. It offers excellent value, especially when compared with competitor products and / or alternative methods of providing fire resistant ductwork.

Non-coated, galvanized ductwork has many benefits. It holds significant commercial and environmental advantages over other systems which employ an intumescent / flame retardant coating.

Coated finishes can involve extra cost and risk throughout the supply chain as chemicals are employed to degrease, etch, prime and apply the coating; additional energy is expended to dry the products and processing time is extended as the coating must fully cure before the product can be used; occupying valuable manufacturing / storage space in the meantime. Any damage during transportation would necessitate its return or replacement; adding unexpected time, cost and logistical effort and, crucially, damage during installation could, if not identified and addressed, compromise the fire resisting integrity of the building

Non-coated product completely negates all the above issues.
The product can be fabricated swiftly and without difficulty, leading to significant time & cost savings in the manufacturing process.
Non-coated product assures that ‘just in time’ or short lead contracts can be fulfilled and that both installation contractors and the Main Contractor can be confident that Plan of Work deadlines will be met, so avoiding potential penalties.
