Method Steps

  1. Install SuperQuilt Under Rafter

    Install the SuperQuilt underneath the rafters horizontally, when installing staple every 300mm to ensure the SuperQuilt hold securely in place. When you have completed this - tape and seal around all the edges and joints using the Thermaseal Foil Joining Tape. This tape is included with the Tyva Quilt Kit.

  2. Batten and Board

    Install battens that have a minimum depth of 25mm. Secure these by going through the SuperQuilt and in to the rafters behind. The gaps between each batten installed should be between 400mm and 600mm. Follow by installing your plasterboard / preferred finish.

  3. Install EcoLoft Non Itch

    Now between the rafters, you can install the EcoLoft Non Itch. We have two different sizes you can choose from depending on your centres (likely to be 400mm or 600mm). One size is 380 and the other 570 - so choose the one most appropriate for your roof. This material is 100mm thick and you simply install this between each rafter. You need to ensure the non itch is pushed back and that you have an air space between this and your breatherquilt.

  4. Install BreatherQuilt

    Now you have installed your non itch, proceed at the bottom of your rafters by installing BreatherQuilt horizontally. Staple every 300mm to ensure secure. Ensure that breatherquilt is draped in to the rafters, it does not need to be pulled taught. Each layer of breatherquilt should overlap by 100mm, the tape is fixed to the breatherquilt to seal the two layers together. Vertically the quilt can be bitt joined and taped with the weatherproof tape.

  5. Install Tile Battens

    When you have installed the BreatherQuilt, ensure you have a 10mm gap between the BreatherQuilt and Tile Batten (in centre of each rafter). At the eaves, BreatherQuilt should extend on to a suitable eaves carrier. Finish with tile or slate finish on tile battens.
