Panoramica

Informazioni su Fire-resistant insulation blankets and duct wraps

Fire-resistant duct wraps are tested on the duct type and size they protect: EN 1366-1 for ventilation ducts (classified under EN 13501-3), UL 2221 / ASTM E2336 for grease duct enclosures and AS 1530.4 in Australia.

Layer count, overlaps, pins, bands and penetration details through walls and floors are defined by the tested system.

A non-combustible blanket alone does not make a duct fire-rated – the tested system does.

Vantaggi principali

Fire-rates ductwork without builders’ work shafts
Thin, light wrap systems
Grease-duct versions for kitchens
Tested penetration details

FAQ

Domande frequenti

Is a mineral wool blanket enough to fire-rate a duct?

Only within a tested wrap system for that duct type – the number of layers, fixings and penetration details matter.
