A selection of Vapour / Airtight control membranes, we recommend our Airstop Timbertex product for most applications that are open diffusion to the outside and of standard construction that includes a typical wall and roof makeup. For Non vapour diffusing makeups such as tanked roofs , torch on felt etc we recommend the use of a variable / intelligent membrane such as our Airstop Diva although checks may need to be carried out. If you are unsure then please contact us .
