CWCT Testing for clients on site

What is CWCT Testing?

What is CWCT

Stroma Built Environment is a member of the Centre for Windows and Cladding Technology (CWCT). On site façade testing can be used to check design performance and the quality of works carried out on site. By testing in the field we can help our clients to mitigate any risks or unexpected costs relating to the future performance of the façade. Benefits of CWCT Testing

  • We accurately simulate the source of leakage to discover and resolve it
  • We accurately confirm whether windows, cladding and facades are water tight
  • We offer reassurance that the façade will perform as expected
