EcoAirtec Double Insulation - High Performing Multi Purpose Foil Insulation

expand_circle_down How-To Guides

How To Install Airtec Double

  1. Measure Area & Cut Insulation

    Measure the area of the section you are insulating. Then roll out the insulation and cut to size. Our insulation can be cut with scissors or a cutting knife, both these can be found in our multifoil fitting kit.

  2. Staple EcoAirtec Double

    To gain the best thermal performance it is recommended to have an air cavity either side if the insulation. Staple the insulation directly on the studs or rafters at 300mm centres. Once the next layer is installed, either horizontally or vertically, ensure the product is overlapped by 50mm.

  3. Tape and Seal with Thermaseal Foil Tape

    It is vital to ensure the insulation is fully taped and sealed using Thermaseal Foil Joining Tape. Our Foil Tape is 75mm therefore this will cover a 50mm overlap. It is crucial to ensure the insulation is fully taped and sealed over all overlaps and around the perimeter. This ensure the product works as a high performance Vapour Control Layer.

  4. Counter Batten Insulation

    Once the insulation is fully covered and taped and sealed, to gain the best thermal performance we recommend installing a counter batten over the top. 19mm deep battens would be suitable, spaced apart around 500mm. This will create a solid finish to screw the internal board to.

  5. Finish with Internal Boarding

    Finish the project by installing internal boarding on the battens. Plasterboard, cladding or timber boards are popular options.

expand_circle_down Q&As

Is this product perforated?

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.

Can this product be used under Laminate?

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.

What’s the best way to install this?

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.

Do I need a gap either side of the AirTec?

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

Can I insulate over the top of electrical cables?

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.

Is Tape Essential?

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.
