Weather Resistance & Durability: Environmental Testing of Construction Products

We know how important it is to consider all aspects of the impact of the working environment on your products. We carry out testing to find out whether products and systems are fit for purpose, and should failures occur, why they have happened.

You want to be sure that your cladding materials, such as, renders, brickwork, concrete, and modern composite cladding, can perform for its intended life cycle, particularly if the requirement of design life is over 60 years. We can subject samples to accelerated weathering and make assessments about their structural integrity and their aesthetics.

Wind-driven rain penetration can be a particular problem when looking at modular construction, timber frame, or lightweight steel frame buildings, as water ingress can cause deterioration of the structural frame and hence affect the load-bearing capacity of the building. Our experts carry out tests under dynamic conditions which represent different levels of exposure. This allows the system to be categorized for use.

Hygrothermal performance testing

Lucideon has the UK's largest selection of hygrothermal testing chambers, performing 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, drying, heating, cooling, freezing, and thawing. To ensure 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 complete performance testing for ETICS, renders, cement particle boards, glass reinforced plastic (GRP), MgO boards, brick slip systems, and cladding.

Our rigs, each with a double aperture capable of accommodating large-scale panels (10 walls in total, up to 7m²), can provide rapid turnaround times, resulting in quicker product development and certification.

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, to the following standards:

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.

Dynamic wind loading and uplift testing

We offer dynamic wind loading and wind uplift tests for walls (including external wall insulation (EWI) systems), façades, roofing membranes, insulation, rainscreens, pitched and flat roofing, solar panels, and veture kits.

Frost resistance testing

Lucideon has developed accelerated freeze/thaw tests for over 45 years. These have been accepted as industry standards and have proved to be equally useful for testing all kinds of materials and assessing performance in severe freeze/thaw conditions.

We are UKAS (United Kingdom Accreditation Service) accredited for masonry walling, roof tiles, and pavers. The tests are accepted by BSI and form the basis for the European standards for frost resistance of masonry units, pavers and roofing tiles made from clay, concrete, natural stone, or reconstituted stone.

Severe exposure

The essential feature of the masonry unit tests is that they are unidirectional. The freezing and thawing cycles attack only one side or face of the samples which, together with the high level of saturation and rapid rate of freezing, simulates conditions in the most severe environments likely to be encountered in the UK. Consequently, if any failure occurs during a test, it is of the same type as that seen in real situations.

The test method for natural stone and clay or concrete roofing tiles is omnidirectional, resulting in freezing action on all surfaces of the samples being tested.
