TIMBER FRAME WALL (External)

How To Install

External Timber Frame Wall Installation

Timber frame without OSB

Apply the SuperFOIL directly to the studs horizontally with the built-in overlap pointing towards the floor. When applying, start at the bottom of the wall working upwards with each layer. We recommend installing the product horizontally for added protection from the elements, however, it can be installed vertically (with no adverse effects) if needed.

If applying the product vertically, start at the highest point and roll the product down the wall.

When fitting the insulation, ensure to keep the product taut whilst stapling into place. Staples should be placed at regular intervals of 50mm-100mm. Then simply cut the SuperFOIL to the required length and repeat the process with the next layer, utilising the built-in overlap and tape to ensure a sealed finish.

At the floor & top of the area, trim the SuperFOIL allowing for a small overlap. Secure the product by fixing battens around the perimeter of the insulation to create an airtight finish. If required, a bead of sealant can be used to attach the SuperFOIL to the wall before fixing the perimeter battens.

Ensure all tears or cuts are sealed fully using SuperFOIL butyl tape or another suitable waterproof tape to achieve an airtight finish.

To finish the installation, install the correct size counter battens vertically on top of the SuperFOIL to create an air gap. The external finish is then fixed onto the battens in line with manufacturer’s recommendations, ensuring that there is no SuperFOIL exposed to the elements.

 

 

Timber frame with OSB

For maximum thermal performance, attach battens securely to the OSB to create an air space either side of the SuperFOIL.
Apply the SuperFOIL to the battens horizontally with the built-in overlap pointing towards the floor. When applying, start at the bottom of the wall working upwards with each layer. We recommend installing the product horizontally for added protection from the elements, however, it can be installed vertically (with no adverse effects) if needed.

SuperFOIL can be attached directly to the OSB without the need for battens first, however, this will decrease the thermal performance

FIXING DETAILS

Windows & Doors Detail

Install SuperFOIL using the correct method for your application.
To finish installation around windows & doors, simply trim the SuperFOIL up to the frame and staple the insulation to the surrounding framework where possible.
Finish installation by sealing all joints with SuperFOIL butyl tape. 

Pipes, Vents & Holes

At penetrations such as vent ducting, pipework etc, SuperFOIL should be trimmed to ensure there are no gaps around the penetration.
Using SuperFOIL Butyl Tape, ensure the SuperFOIL is well sealed around the penetration to create an airtight barrier. This can be achieved by using small sections of tape and working around the penetration.

At penetrations such as vent ducting, pipework etc, SuperFOIL should be trimmed to ensure there are no gaps around the penetration.
Using 100mm Superior Foil Tape ensure the SuperFOIL is well sealed around the penetration to create an airtight barrier. This can be achieved by using small sections of tape and working around the penetration.

Attach SuperFOIL to rafters using correct method for your application , install up to the purlin and then cut the insulation, leaving enough product to fix into place on the side of the purlin.
Staple securely into place and seal the joint with SuperFOIL 100mm foil tape.
Further secure the SuperFOIL by placing a counter batten against the purlin, ensuring that the SuperFOIL is compressed tightly between the batten and purlin.

Attach SuperFOIL to rafters using correct method for your application.
At the purlin, cut the SuperFOIL to the correct length to be able to be passed underneath the purlin with a small amount of product on the opposite side.
Join the next piece of insulation, ensuring to tape the joint with SuperFOIL 100mm foil tape.
Finish the installation by installing counter battens directly on top of the SuperFOIL to the rafters.
