When to use foil tape

When to use foil tapeThe type of project on which you are working and the materials you choose to use will determine how and when to use foil tape. Foil tape comes with a number of benefits. These include being self-adhesive, easy to install, and heat and light reflective. As you would expect, there are a number of foil tapes to choose from, which includes top brands recognised for insulation such as SuperFOIL, Bond It and Novia.

When to use foil tape

You should use foil tapes when you are hoping to achieve air tightness and moisture resistance. They can be used across a number of applications thanks to their versatility and durability. These include insulation, ventilation and air conditioning projects.


The key benefit to using foil tape with insulation is that it reduces or prevents any air leakage. It is suitable for use with foil-faced PIR boards, multifoils and vapour control layers. However, some insulation products require specific foil tapes in order to guarantee this. For example, SuperFOIL multifoil insulation recommends using SuperFOIL SUPERIOR foil tape to ensure that the insulation performs to the best of its ability. Foil tape can be used in both roof and wall applications.

If you are overlapping vapour control layers or damp proof membranes, foil tapes are a solution for sealing any edges. NOVIA VCL foil tapes are high tack and easy to install in walls and ceiling of insulated building structures.

Ventilation and air conditioning systems

Leaks in a ducting system can lead to wasted energy and increased bills. Seal any joins or gaps using foil tape, which adheres to ducts. This will help to reflect any heat or light whilst providing excellent moisture resistance.

It is important that you clean and dry a surface before applying the foil tape. This helps minimise the risk of dirt or dust compromising the application. Simply cut the length of foil tape required and smooth it over the seam. Bond-It aluminium reflective foil tape can be used on ducting systems to help protect wires and pipes from heat.
