Airtec is un-perforated. It works instead as a vapour control layer. Once you have taped and sealed AirTec – you will prevent passage of moisture. This will in turn remove the risk of condensation.

We would advise using EcoTec Floor Foam instead as the AirTec has air filled pockets, which could decompress under the weight and massively impact its thermal performance. The EcoTec Floor Foam has a dense foam membrane so is better suited for that application.

We would advise applying Airtec by stapling it, to rafters / battens depending on your application. You should use 14mm staples, which come with our Heavy Duty Staple Gun Kit, if you don’t already have them.

We do recommend that you have an air cavity either side of the product of a minimum of 25mm, to maximise its performance. It will trap low emissivity air within the cavity, enhancing its thermal performance.

So long as the cables are not in direct contact with the AirTec, its ok to have the cables underneath. You could always encase them in trunking for extra protection. If you need to pull the cables through the insulation, that is also ok – just ensure you tape and seal around where you have cut.

It isn’t essential, but it is advisable for most applications. To achieve a vapour control layer you need to use the Thermaseal Foil Joining Tape around all of the edges and joints. You can always get in touch via our Contact Us Form, if you would like assistance on any specific application.
