Hygrothermal Performance Testing

Lucideon has the UK's largest hygrothermal testing chambers

Hygrothermal Performance Testing of External Thermal Insulation Composite Systems (ETICS) to EADs 040083-00-0404 and 040287-00-0404, CWCT Standards, M.O.A.T. 22 & Customized Programs.

The external walls of buildings are exposed to a wide range of weather conditions, including: wetting and drying, heating and cooling, freezing and thawing, to name but a few. To ensure External Thermal Insulation Composite Systems (ETICS) perform satisfactorily, and to predict their expected design life, sample panels must be subjected to accelerated testing.

At Lucideon, we have the capability to provide ETICS testing for the complete performance requirements of EADs 040083-00-0404 (former ETAG 004) and 040287-00-0404, CWCT Standards and M.O.A.T. 22. The hygrothermal performance tests assess how products and materials react over time when exposed to extreme changes in humidity and temperature.

M.O.A.T. 22 and EAD 040083-00-0404 test programs are aimed at renders, however, the analysis can also be applied to other materials and finishes: cement particle boards, glass reinforced plastic (GRP), MgO boards, brick slip systems and cladding to the following standards:

  • EAD 090062-00-0404 (Former ETAG 017)
  • EAD 040914-00-0404 (Former ETAG 034).

Through the investment in two new rigs, each with a double aperture capable of accommodating large-scale panels (up to 7m2), we are able to provide rapid turnaround times, resulting in quicker product development and certification.

UKCA-CE Marking

Testing to EAD 040083-00-0404 is necessary to obtain UKCA or CE marking for render products. Lucideon is accredited to ISO 17025 and can provide testing support to certify products for UKCA and CE marking purposes.

Product Guarantees

The M.O.A.T. 22 test program can be combined with structural strength and wind loading tests to predict the expected lifetime of a render product, thus allowing manufacturers to guarantee the lifetime of their products. At Lucideon, we have the capabilities to conduct both static and dynamic wind load testing.


1In 2019 Lucideon entered into an agreement with Technical and Test Institute for Construction Prague (TZUS) to ensure Lucideon's continuity programme for operation as a notified body under the Construction Products Regulations (EU) 305/2011 (CPR).
