Aluminium Foil Tape – 50mm × 45m | BS 476 Class O & Fire Class M1 | Flame Retardant | HVAC & Insulation
This aluminium foil tape is used to seal joints in thermal insulation systems, duct lagging and HVAC pipework. It's built from 30 micron aluminium foil with a high-tack acrylic adhesive, and shouldn't be confused with silver-coloured general-purpose "duct" tape sold at DIY retailers — there's a meaningful difference when fire safety and building code requirements come into play.
This tape meets BS 476 Parts 6 and 7, the UK standards covering fire propagation and surface spread of flame, achieving Class O and Fire Class M1. That makes it suitable for air handling ductwork and pipe lagging in applications where fire performance is specified or mandated by local building authorities, unlike standard duct tape which doesn't carry these ratings.
The 30 micron aluminium foil is reflective and moisture-resistant, providing both a thermal barrier and a vapour barrier at insulation joints, and stays dimensionally stable across its -20°C to +110°C service temperature range — considerably wider than typical duct tape. The high-tack acrylic adhesive also retains its bond at higher operating temperatures where a standard rubber-based adhesive would soften and lose grip. A polythene-coated release backing allows easy, consistent application without tearing or stretching the foil. Application temperature is 0°C to 40°C.
Key Features & Benefits
BS 476 Part 6 & 7 Compliant – Class O & Fire Class M1: Meets UK fire propagation and surface spread of flame standards for regulated building services applications.
-20°C to 110°C Service Temperature: Covers cold store pipework at one end and HVAC hot ductwork and flue lagging at the other.
30µm Aluminium Foil: Reflective, moisture-resistant and dimensionally stable, providing a vapour barrier at insulation joints.
High-Tack Acrylic Adhesive: Retains bond at operating temperatures, unlike rubber adhesives which soften and lose grip at higher temperatures.
Polythene-Coated Release Backing: Easy peel application with consistent adhesive coverage.
50mm Wide, 45m Roll: Practical width for covering insulation jacket joints and duct seams in a single pass.
Application Temperature 0°C to 40°C: Suited to normal indoor application conditions.
Ideal For
HVAC duct sealing, including joints on rigid and flexible ductwork.
Pipe and duct lagging, sealing mineral wool, fibreglass and foam insulation jacket joints.
Flue and air distribution pipework insulation.
Emergency roof and gutter repairs requiring a weatherproof, moisture-resistant seal.
Marine and industrial applications requiring a heat and moisture resistant tape.
Why Buy This Product?
Unlike general-purpose duct tape from a DIY retailer, this tape carries genuine fire performance ratings under BS 476 Parts 6 and 7, which matters wherever fire safety is specified or mandated by building authorities on HVAC ductwork and pipe lagging. The acrylic adhesive holds its bond across a much wider temperature range than a rubber-based alternative, and the 30 micron foil provides both a reflective thermal barrier and a moisture barrier at insulation joints — genuinely different performance to standard duct tape, not just a different colour.
