Modular Accreditation & Approvals
Wetherby are at the forefront for testing and approving systems for Modular Construction and have Modular Accreditation & Approvals to BBA/ BDA standards with full Premier approval.
Despite having one of the widest ranges of External Wall Insulation Systems in the UK, we are proud to be actively involved in numerous Research and Development projects, that will allow us to keep at the forefront of our industry for many years to come.
New product development and testing is a very valuable investment to our company and we are always looking for innovative, cost effective alternatives to traditional EWI and render activities.
