Rainscreen cladding provides an exterior surface – a cladding layer – that stops the force of wind-driven water movement, preventing it getting through small breaches in the surface of a building.
By the time the water reaches the ‘true’ exterior wall, it has lost its drive and therefore its ability to permeate the wall, hence the origins of its name: rainscreen cladding.
There are a wide range of benefits to using rainscreen cladding. For example it provides enhanced thermal performance, allowing designers to create very efficient thermal envelopes to meet the highest environmental standards. It is simpler and quicker to install than traditional constructions and provides excellent sustainability benefits to the overall project.
Sotech design, engineer and manufacture the Optima range of rainscreen cladding systems, each system has been witnessed and certified by CWCT for wind serviceability and safety, air permeability, water penetration and soft body impact. The most recent tests for the Optima FC+, TFC+ and Edge also includes hard body impact testing.
CWCT testing, together with good design and installation, can provide ultimate peace-of-mind that the product will deliver the intended performance.
Sotech has also completed a range of full scale fire tests on its core systems, successfully fire testing to BS8414-2 and gained BR135 classification and can therefore offer true A1 fire tested systems. This test provides a test method for determining the fire performance characteristics of non-loadbearing external cladding systems, fixed to and supported by a structural steel frame when exposed to an external fire under controlled conditions.
Any deviations or product substitutions from that which was tested are strictly subject to BS 9414
