Exova Warringtonfire Fire Tests to EN 13501-1

Exova Warringtonfire are a UKAS accredited testing and certifying organisation who have classified all Ash & Lacy systems to the most rigorous standards available for systems which form part of the exterior of a building: BS EN 13501-1:2018. Under the newest UK Building Regulations (amended in November 2018) any component which forms part of an external wall on a ‘relevant’ residential building must achieve either Euroclass A2-s1, d0 or Euroclass A1 to the classification standard EN 13501-1, or be classified A1 without testing according to Commission Decision 96/603/EC. All of Ash & Lacy’s tested systems have achieved Euroclass A2-s1, d0 or Euroclass A1 to EN 13501-1, as you can see below:

Centre for Window and Cladding Technology (CWCT) Tests

CWCT (Centre for Window & Cladding Technology) Standard Test Methods for Building Envelopes determine the level of serviceability of a façade or rainscreen cladding system when subjected to typical climactic levels of water, air and solid object impact. The final classifications derived from the results depend on factors such as the maximum air pressure reached or the severity of damage after an impact.

A Centre for Window and Cladding Technology member, Ash & Lacy ensures all applicable rainscreen cladding systems are subjected to these test standards and will achieve the values expected.

For ease of reference, our latest test results are summarised on this page.
