TyvaQuilt consists of three products building regulations. 1st is SuperQuilt Under Rafter, 2nd is Non-Itch between Rafter and finally BreatherQuilt Over Rafter. Start by installing SuperQuilt under rafter. Staple SuperQuilt and roll the product out horizontally, staple at 300mm internals. Ensure all overlaps are fully taped and sealed using Thermaseal Foil Joining Tape.
Once SuperQuilt is fully stapled & taped on the rafter, you can next proceed with your counter battens. Install battens min 25mm through SuperQuilt into the rafters behind. Ensure battens are spaced between 400mm & 600mm. Once the battens are installed, proceed with installing a plasterboard in the usual manner.
BreatherQuilt and SuperQuilt are to be stapled using a Heavy Duty Staple Gun & 14mm Staples. All three product can be cut using the Multifoil Scissors or the cutting knife. All these accessories are available in our Multifoil Fitting Kit.
Next, install EcoLoft Non Itch Wool in-between the rafters. EcoLoft Non Itch is designed to suit either 400mm or 600mm centres, with the product supplied in 380mm width or 570mm. EcoLoft Non Itch is supplied in 100mm thickness. Simply stuff the Non-Itch Wool between each rafters, leaving an airspace above for the BreatherQuilt.
Once EcoLoft Non Itch is installed, proceed to install BreatherQuilt. Start at the bottom of the rafters, roll BreatherQuilt out horizontally, stapling at min 300mm intervals. Ensure BreatherQuilt is draped into the rafters as opposed to being installed taught. Horizontal overlaps should be overlapped by 100mm, tape using Thermaseal Double Sided Tape. Vertical joists are butt jointed, and taped using waterproof tape.
Once BreatherQuilt is fully covered on the rafters, proceed by install tile battens. Ensure there is a gap of 10mm between BreatherQuilt and Tile Batten (in center of each rafter) At the eaves, BreatherQuilt should extend onto a suitable eaves carrier. Finish with tile/slate finish on tile battens.
