SF19 – High tech foil insulation

SuperFOIL SF19 is the UK’s best value multi-layer foil insulation. Consisting of 19 layers of reflective foil and thermo foam separation layers SF19 provides exceptional performance at affordable costs.

In situ energy assessment indicates that multilayer foils have benefits over traditional (non reflective) insulation. SuperFOIL SF19 provides a barrier to the movement of air and controls air leakage. The control of air leakage is essential to the further improvement of energy efficiency.

SuperFOIL SF19 is also CE certified for its performance as a vapour and water barrier. It is easier to handle, install, cut, and seal than other forms of building insulation, and has a life expectancy in excess of 50 years. Performance is tested to the standards required and approved for Building Regulations by UK Certified Test laboratories.

SuperFOIL has fully woven outer foil layers making it the strongest multifoil material aiding installation and reducing waste. SuperFOIL is LABC Registered System approved which helps streamline Building Regulation applications saving time and money!

European Technical Approval (ETA)

The EU has proposed under ECPD 1989 OJ L106/1 a new technical standard is to be developed that will incorporate the full performance of multi layer foils under real conditions including radiant reflective properties and air seal properties. This will ultimately result in a new CE or ETA classification.

Installation Guide

Under or Over Rafter

Apply SuperFOIL directly to the rafters from the roll either horizontally or vertically.

For over rafter start at the bottom and work up the roof overlapping at each junction. For under rafter start at the high point and work down, overlapping at each junction as you add the layers.

When installing vertically start at the high point and roll down the rafter.

Apply tension to the SuperFOIL as you staple in place; staple into the rafters with staples inserted at regular intervals, 50mm to 100mm spacing is recommended. Cut to length and fix the next layer.

Overlap all joints by a minimum of 50mm and staple onto the rafters where the joint crosses the rafter. Seal all joints using SuperFOIL tape.

At the eaves trim SuperFOIL around the rafters and seal to either the wall plate or the Cavity wall insulation if present.

To fix plasterboard when using SuperFOIL under rafters. Install battens sized according to the product used (SF19 = 25mm); at right angles to the rafters. Always apply battens around window reveals.

Apply tape to any tears, cuts or joints before fixing plasterboard to the battens.

For walls

Fix vertical battens to the wall appropriate to the material being used. Position the SuperFOIL across the wall horizontally and staple to the face of the battens stapling at 50 to 100mm centres.

Repeat for each layer as needed overlapping by at least 50mm with each layer. Trim as required and staple and tape all joints.

Batten around window reveal perimeters with battens and secure the SuperFOIL to them. Then fix a counter batten horizontally and finally fix the plaster board to this batten.
