Heat Insulating Adhesive & Aluminium Foil Tape
Heat Resistant Aluminium Foil Tape

This is pure aluminium foil tape in either a 0.03mm or 0.07mm thickness. Great for many repair jobs at home but also useful on the car and can reflect heat from intake pipes and other heat sensitive engine parts
Shop NowReinforced Heat Resistant Aluminium Tape

The Kool Wrap Reinforced tape has a reinforced fibreglass backing and a real aluminium foil outer face. Ideal where you need a stronger tape capable of withstanding temperatures up to 600°C.

This tape is 1.3mm thick and has a real aluminium foil facing backed by a thick woven fibreglass backing. The fibreglass provides a real insulation layer between the foil and the product or surface you wish to protect. Many uses including on aircraft, racing cars and boats and even in industrial kitchens.

Heat resistant tape vs heat reflective tape
Heat reflective tape has a foil face that bounces radiant heat away from whatever it covers. Heat resistant tape is built to survive near heat without the adhesive or backing failing. The best tapes for engine bays do both: a reflective aluminium face on a fibreglass backing that adds strength and insulation. Plain foil tape reflects heat but has no insulating layer, so it suits sealing and lighter jobs.

Choose your tape by the job
- Sealing joins in foil insulation, van liner or ducting: standard aluminium foil tape.
- Spiral wrapping a hose, wiring loom or intake pipe near heat: reinforced foil tape.
- Adding insulation to an airbox, intake tube, firewall patch or fuel line: fibreglass-backed tape.
- Sealing cut edges and joins on an adhesive heat shield: aluminium foil tape.
- Matching gold heat shielding: Gold Reflecta Shield reinforced tape.
How to apply heat tape so it stays put
- Clean the surface with a degreaser and let it dry fully. Adhesive fails on oil, dust and moisture.
- Work in mild conditions. Warm, dry surfaces bond best.
- Cut the tape to length before you peel the liner.
- Press it down firmly and rub it flat with a cloth or roller to push out air.
- On hoses and looms, spiral wrap with an even overlap and finish on the underside, away from direct heat.
Where tape is the wrong product
Tape protects parts near heat. It is not built to go directly onto exhaust pipes, extractors, manifolds or turbo housings. Use exhaust heat wrap on pipes, a turbo blanket on the turbine housing and a heat shield for larger panels. For hoses and wires close to the heat, a heat sleeve gives more protection than tape.
