At only 4mm thick YBS Airtec Double is our thinnest insulation for Roofs, Walls, Floors, Conservatories, Greenhouses, Sheds, Summerhouses and Motor-homes.

YBS Airtec Double consists of a highly reflective aluminium foil with a laminated surface for durability either side of an air bubble membrane. This membrane effectively acts as a Vapour Control Layer when fully taped and sealed using ThermaSeal Foil Joining Tape.

With an R-Value of 1.45 Airtec Double is equivalent to around 55mm of Polystyrene and it is the DIYer’s go-to insulation as it is thin, flexible and extremely easy to install.

Download our Fitting and Data Sheet or view our How-To Videos to see how easy it is to install Airtec Double in your project.

Looking for a higher performing product? Our best multifoil when comparing performance to cost is our EcoQuilt Expert material. EcoQuilt is suitable for all the same applications as Airtec however close to double the performance.

If your order is over £100+Vat and ordered before 2pm we deliver this free of charge on a Next Day Service.

When spending over £500+Vat we also supply you with a Free Heavy Duty Staple Gun and 5,000 x 14mm Staples.
