Product approval & certification

BBA certification is recognised throughout the construction industry as a symbol of quality and reassurance. It's the vital ingredient in the provision of assurance, quality and integrity to a plethora of stakeholders in the construction industry.

Weather Resistance & Wind Serviceability

Understanding how a construction product or system will perform under real-world applications of weathering is critical. 


The characteristics and behaviour of the different materials and elements directly affect the safety and durability of buildings. For this reason, they undergo specific tests in Weather Resistance & Wind Serviceability to establish the quality levels and to guarantee their adequacy. 

Below are some of the tests that determine the real-world application of weathering. 

  • Physical involving the breaking down of materials through direct contact with atmospheric conditions such as heat, cold, water, ice or wind.
  • Chemical assessing the adverse effects of atmospheric or biologically produced chemicals.

There are two types of weathering that must be considered, both of which occur together and using a weathering chamber and wind tunnels, we can reproduce such conditions and the subsequent impacts at both discrete component and large systems levels. After exposure to adverse climate conditions, a diverse range of complementary tests can be performed to evaluate the residual performance of the specimens. 

These tests include:

  • Cladding
  • Roofing
  • Walling

which are some of the systems commonly tested at our facilities.
