Smart's MC Wall passes CWCT standard

The rigorous testing took place at the Taylor Woodrow Technology Centre in Leighton Buzzard under the strict guidance of CWCT University of Bath. MC Wall achieved an excellent performance, making it suitable for the most extreme exposure categories in the UK; air permeability Class 4 600pa, water tightness Class R7 600pa and wind resistance 2400pa.

Modern building envelopes are expected to meet many performance criteria such as safety, building physics, integrity and durability and hence must undergo stringent testing to ensure its performance is long term. The CWCT standard for ‘Systemised Building Envelopes’ is widely regarded as the benchmark certification for ventilated facades; the standard has been updated to include the stipulations of European EN Curtain Walling standards, and now all test requirements are at least equal to the European standards, and several even surpass those standards; a example being the water penetration tests.

The current CWCT standard has retained the dynamic aero engine test, which is the only suitable method of simulating typical weather conditions on a building envelope. The dynamic test attempts to recreate these conditions by using a large wind generator to develop turbulent positive pressure while water droplets with kinetic energy are sprayed over the face.

Smarts are committed to high standards of quality and workmanship; their reputation has been built around the assurance of quality that comes with buying a Smart product. Attaining the CWCT standard demonstrates that the company’s policy of extensive product testing continues to ensure their products perform to the highest standards; their range also features products that hold BSI Kitemark BS 7950, and PAS 23/24 certificates.
