Cranleigh School

For a stunning new eco building at Cranleigh Prep School in Surrey, the specification of the proven and durable alwitra Evalon® V single ply waterproofing membrane and the fine detailing of TAG edge trims from ICB ensured long lasting performance whilst maintaining aesthetic appeal.

With the need to develop new facilities due to the growth in pupil numbers, Cranleigh Prep School decided to create three new classrooms which were as environmentally friendly as economically feasible.  Designed by architects Blue Forest, the resulting timber framed building is made all the more distinctive by the deep aluminium soffit that extends around the roof of the building. 

To achieve the desired aesthetics and exceptional detailing for the roof, specialist roofing contractor SW Roofing Solutions installed 350m2 of Evalon® V single ply membrane due to its workability and long lasting performance while 50 metres of TAG 350 edge trims with concave and convex curves met the client’s brief for exceptional detailing and a 100% watertight seal.

Specified for its world class waterproofing qualities, alwitra Evalon® V is a unique membrane that provided the project with the ultimate low cost, long term solution to its waterproofing.

It can be fully adhered using a range of special adhesives, as well as mechanically fixed, loose laid and ballasted. Alternatively it is available in a specially developed self adhesive backing – ideal for flame/heat free environments.

Alwitra Evalon® V is just one product in a wide portfolio of highly engineered products making up ICB’s Ultimate Roofing System. This includes fine quality flashings, edge trims, roof lights, rainwater outlets and every component for extensive or intensive green roofs. Every ICB roof is protected by a comprehensive guarantee that gives cover for up to twenty years.

As a one-stop-shop for metal fabrications, ICB’s sister company ICB Fabrications has the ability to provide bespoke products using state-of-the-art machinery in order to produce a wide range of architectural metalwork using aluminium, stainless steel, galvanised or pre-coated steel. 

With the building now complete, ICB has ensured a long term watertight seal whilst at the same time making a significant contribution to the overall aesthetic appearance of the school.
