Rain Clad is a non-combustible cladding insulation designed and developed by our highly experienced engineers for best performance for all external cladding applications.

is suitable for ventilated or non-ventilated External cladding applications at any height including buildings over 18m.

With significant thermal and acoustic performance, the heat and cold lose through the wall are significantly reduced.

With the factory-applied water repelling agent, Rainclad prevents water ingress during construction and can be left exposed whilst awaiting final cladding solutions
