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.
