Textured aluminium sheet combined with a self-adhesive rubber/bitumen compound suitable for exposed flashings and flat deck roof membranes

Product Description

Solarshield™ is a robust, cold-applied, self-adhesive, heavily textured aluminium membrane which can be used as a conformable solar reflective flashing or protection for exposed roofing membranes.


Solarshield comprises a thick aluminium sheet which is heavily embossed to accommodate both transverse and longitudinal movement. A thick, self-adhesive rubber/bitumen compound is laminated to the underside to provide adhesion to primed substrates and all membranes from GCP Applied Technologies.

It is supplied to sites in rolls 1m wide x 10m long, 1.5mm thick overall and is normally unrolled and cut to size before applying sticky side down on to primed concrete or membrane surfaces to which it bonds firmly.

Continuity is achieved by overlapping 75mm on sides and ends and well rolling the joint to promote bonding.

When Solarshield is used as a flashing, it should be pre-measured to size before applying to ensure that it is terminated into a primed chase or securely fastened by a cover strip to prevent moisture by-passing the waterproofing.

A hot climate grade (HC) is available to suit higher ambient temperatures.

Storage Dry conditions below +30ºC


The installation of the Solarshield should not be carried out at temperatures below -5°C. At air temperatures below 4°C measures should be taken to ensure that all surfaces are free from ice, frost or condensation.

The underlying roof waterproofing membrane must be clean and surface dry before applying the self-adhesive Solarshield. When used as a flashing, pre-measure the extent of the Solarshield to accurately follow the roof profile to the termination chase, or mark out the free board height if metal counter flashings are used to securely fasten the leading edges.

Pre-bending or shaping the Solarshield to the correct profile before removing the silicone paper will assist with the application.

Solarshield should be laid by peeling back the protective silicone release paper and carefully offering the adhesive face into position on the prepared surface. Cut and trim carefully around internal and external corners to form an effective protection flashing to the waterproofing membrane beneath. The material should be brushed on to the surface to ensure good initial bond. Adjacent widths should be aligned and overlapped 75mm minimum at side and ends, and well rolled with a firm pressure using a Bituthene Lap Roller to ensure complete adhesion and continuity between the layers. Laps should be staggered between layers to prevent a build-up of layers.

In cold weather conditions the application of warmth will aid adhesion.
