EN 1366-1 & 8 SYSTEMS
CASWELL FIRESAFE® non-coated fire resisting ductwork systems are classed as Passive Fire Protection and have achieved the verified fire resistance to protect against the spread of fire from one compartment to another within a building.
They provide this assurance without the need for enclosures, spray coatings or fabric coverings.
CASWELL FIRESAFE® product is now available to EN 1366-1 & 8 for up to 120 minutes Integrity and up to 120 minutes Insulation for both Fire Outside Duct (Type A) and Fire Inside Duct (Type B) scenarios.
In December 2020, we added a further system variant which provides up to 60 minutes Integrity and up to 60 minutes Insulation (Type A & B) for use in applications that only require this duration of fire resistant performance.
Go to BS476:Part 24 (1987) for details of our British Standard range.
Following the introduction of the Construction Products Regulations (CPR), we undertook to meet the testing standards EN1366-1 & 8 and comply with product standard EN-12101-7. Achieving these objectives enables us to offer in-scope CE-marked product for the European Economic Area (EEA).
CASWELL FIRESAFE® products are also used for Smoke Control; quickly and safely exhausting smoke and, as an integral part of a pressurised system, preventing it from entering protected escape routes to maximise valuable escape time. Ducts which penetrate compartment walls and floors must achieve the same fire resistance as the compartments through which they pass.
