Hose Testing

Suitable for closed joint curtain walling and sloped glazing systems. For these types of systems, tests are conducted to determine resistance to water penetration, including joints and interfaces which are intended to be permanently closed and watertight. Each installation will ensure a representative sample is hose tested in accordance with the current CWCT Standard and ensure a minimum of 5% of the completed system is tested.

Spray Bar Testing

Suitable for open-jointed systems for example: rain screen cladding, unsealed patent glazing and opening joints, as water is not forced into the joint. This test can also be used to identify leakage in cladding, curtain walling systems, roofs and skylights.
