Ultra-Thin Foil-Tec Single Insulation

This is a reflective 2 in 1 insulating Vapour Control Layer. Foil-Tec Single Lite 1.5m x 50m has a laminate coating, providing you with a robust product that also is resistant to corrosion.

This material will increase the thermal performance, without losing any space. The beauty of this product is that it really is ultra-thin, which therefore makes it flexible and easy to install.

The shallow nature of the Foil-Tec Single product doesn’t compromise its vapour control and insulating benefits. It provides a barrier to air leakage, so reduces the rate of heat loss.  This equates to 32mm Mineral Wool despite being less than 1mm thick!

We recommend to fully taped and seal with product with Thermaseal Foil Joining Tape. This will ensure the product works as a VCL – preventing moisture passing and reducing the risk of condensation build up. It does so by creating an insulating barrier between where the warm meets the cold surface.


This is a fully certified product; meaning it is Agrément Certified, Building Control compliant and NHBC accepted. Foil-Tec Single Lite 1.5m x 50m is fully certified to the latest standards in the industry by BDA Kiwa.

Foil-Tec will enhance the U-values in Roofs, Walls and Floors.

This reflective foil has a certified R-value in a roof of 0.490m²K/W, and 0.740m²K/W in a wall.

How thick is the FoilTec Single?

FoilTec Single Lite is a highly reflective foil insulation which is less than 1mm in thickness. This product is commonly used in lofts, floors and walls to save on cost, space and installation time compared to traditional products.

Can I use this product behind plasterboard?

Yes, FoilTec Single can be installed directly behind plasterboard, stapled to rafters or battens. When this product is fully taped and sealed, FoilTec Single Lite will act as high performing vapour barrier, eliminating condensation.

Can this product be used in Roofs?

FoilTec Single is commonly stapled to roof rafters to help reflect and retain more heat during the winter, saving on energy bills. It also helps reflect away excess heat in the summer, keeping your property at a more ambient temperature all year round.

Does FoilTec act as a vapour barrier?

Yes, when fully taped and sealed with ThermaSeal Foil Tape, FoilTec Single Lite will act as a high performing vapour barrier, eliminating the risk of condensation.

Do I need an air space on both sides of the insulation?

All multi foil insulation products work best by creating a cavity of at least 25mm on both sides of the insulation. This allows the foils to reflect properly and reduces cold bridging.

How is this superior to a conventional vapour control layer?

Foil-Tec provides more strength and thermal performance compared to a traditional VCL.

Is this product accredited?

Yes - Foil-tec can be applied to enhance ‘U’ values in new build or refurbished building project to meet and exceed current building regulations.

Should I install this product vertically or horizontally?

This can be installed either vertically or horizontally - choose the most appropriate direction depending on your wall height.

Do I need to tape this product?

We do advise using our Thermaseal Foil Joining Tape around all of the joints and edges this ensures no passage of moisture.
