Testing & Certifications

Welcome to the Ash & Lacy Testing & Certifications page.

Ever since its beginnings in 1864, Ash & Lacy has been committed to ensuring that its products carry proof of the highest quality and safety standards.

For the construction industry, Ash & Lacy products and systems are regularly tested by independent UKAS accredited organisations such as the Centre for Window & Cladding Technology (CWCT) and Exova Warringtonfire and Lucideon, and accredited by globally recognised bodies such as the British Board of Agrement. Through this continued investment in testing alongside innovation and product development, we strive to give our customers the peace of mind that Ash & Lacy products are not only compliant with the latest Building Regulations, but will also stand the test of time.

Using the tabs below, navigate through our latest test results.

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.

Exova Warringtonfire Fire Tests to EN 13501-1

Exova Warringtonfire are a UKAS accredited testing and certifying organisation who have tested various Ash & Lacy systems to the most rigorous fire testing standard available for systems which form part of the exterior of a building: BS EN 13501-1:2007+A1: 2009. 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.
