Measure the amount of material required for your first strip and cut. It is most common for customers to insulate horizontally, but the choice is yours.

Staple the Multifoil to the underside of the Roof Rafters. We advise stapling every 300mm to ensure that the material is held securely in place. Pull the material nice and straight where possible, to keep it neat and also to make the cutting process easier for you too.

When installing your second layer, overlap the material onto the former layer by 50mm. Continue insulating until you have full coverage, following the above instructions.

You may wish to leave the insulation exposed - which is fine. However, it is quite common for customers to nail/screw battens into place before boarding - if they are wanting to create a usable room. This is not required but is a popular option.

You can double the performance by installing two layers. To save on space, you recess the first layer to the side of the roof rafter. This way, you still have an air cavity behind the product, but you also have an air cavity between the first and the second layer too.

Continue installing your first layer until you have full coverage.

Start by installing 25mm battens directly onto the solid wall, horizontally or vertically at 400 to 600mm intervals.

Next, staple SuperQuilt onto the first set of battens, then roll out SuperQuilt horizontally. We recommend the use of 14mm staples when fixing SuperQuilt. This can be purchased as part of our EcoPro Multifoil Fitting Kit!

Ensure all SuperQuilt Insulation joints are overlapped by 50mm. Ensure overlaps are fully taped and sealed using Thermaseal Foil Joining Tape. Ensure SuperQuilt is also fully taped and sealed around the perimeter. SuperQuilt can be easily cut using Multifoil Scissors or a Cutting Knife - Both available in our EcoPro Multifoil Fitting Kit.

Now it’s time to install your 25mm counter batten. Again, horizontally or vertically at 400 to 600mm intervals. We recommend these counter battens to be fixed to the initial battens. We also recommend creating a frame around any windows and around the perimeter.

The plasterboard is then screwed into the battens in the usual manner. When SuperQuilt is installed as the most internal insulation layer, there is no requirement for a foiled-back plasterboard. SuperQuilt will work as a high performing Vapour Control Layer, when taped and sealed using Thermaseal Foil Tape. Optional Insulated Plasterboard's can be used for extra thermal benefits dependant on U-Value required.

Firstly roll out the SuperQuilt to the desired legnth and attach the SuperQuilt to wooden purlins or rafters using staples or nails at 200mm intervals, we recommend to lip the SuperQuilt round the top of the Purlin and staple onto the back of the purlin as shown in our image below. This will allow the purlin to take the weight of the SuperQuilt.

Ensure SuperQuilt is butt jointed with other layers on both the verticals and horizontals. (No overlaps). Fully tape and seal all butt joists of SuperQuilt with Thermaseal 75mm ThermaSeal Foil Joining Tape.

Timber battens or joists are then laid over the top of SuperQuilt - at 400mm centres (evenly spaced). The minimum batten depth is 50mm, increasing the batten depth enhances the performance. SuperQuilt will compress to around 7mm when timber is installed above.

Proceed with installing your timber boarding floor. The deck is then fixed at 200mm centres, with 37mm screws into the joists or battens below

Firstly, install YBS BreatherQuilt on the external of the pitched roof. Ensure the reflective foil is facing internally with the Breather membrane facing outwards. Starting at the bottom of the rafters, staple BreatherQuilt to the first rafter using 14mm staples (recommended 300mm intervals). Roll BreatherQuilt horizontally across each rafter, stapling continuously. BreatherQuilt should sag between the rafters as opposed to being pulled taught. Ensure that once the tile battens are installed, there is a clear 10mm gap between the top layer of BreatherQuilt and the tile battens.

Next, install a further layer of BreatherQuilt, overlapping the product by 100mm and seal using the built in double sided tape. Staple as previously and ensure the tape is secured and sealed. This is to be repeated dependent on how many runs are required for the roof. Additional rolls on the verticals should be butt jointed on the rafters. Ensure the butt jointed rolls are stapled as previous and taped using waterproof tape.

At the eaves, BreatherQuilt should extend onto a suitable eaves carrier. This works in the same method as standard breather membranes. Proceed next by installing horizontal tile battens, on the top of the BreatherQuilt. Finally, finish by install tiles or slates.

Both layers of SuperQuilt can now be installed from the internal (underside) of the rafters. The first layer of SuperQuilt is to be recessed in-between the rafters, the 2nd layer of SuperQuilt is to be pulled taught as a flat continuous layer, ensuring that there is a clear cavity between both layers of SuperQuilt and BreatherQuilt.

SuperQuilt is stapled to the underside of the first rafter. SuperQuilt is next recessed into the rafter (25mm), and fixed with staples of with battens. The material is then pulled taught and fixed to the opposite rafter. SuperQuilt is then wrapped around the rafter, ensuring stapling regularly, and the procedure starts again. SuperQuilt is overlapped by 50mm, ensure fully tape and seal using Thermaseal Foil Joining Tape over the laps and around the perimeter.

Once the first layer of SuperQuilt is installed, proceed by installing the second layer. Staple or nail the second layer through the first layer into the rafters behind. Ensure this layer is also pulled taught, there will then be a cavity between the two layers of SuperQuilt. As per the first layer, the second layer is also overlapped by 50mm. Ensure again the product is fully taped and sealed around the perimeter and overlaps using Thermaseal Foil Joining Tape.

Once both layers are installed and taped, you are ready for your secondary batten & plasterboard. Start by installing 25mm x 38mm battens on the insulation. We advise to cross-batten, however vertical battens can be used if preferred. Finish by installing 12.5mm Plasterboard. There is no requirement for a Foiled-back plasterboard or VCL. SuperQuilt works as a high performance Vapour Control Layer when taped and sealed using the ThermaSeal Foil Tape.
