External Thermal Insulation Composite Systems (ETICS)

External thermal insulation composite systems (ETICS) or external wall insulation systems (EWIS) are used to improve the thermal performance of a structure. BBA Test Services has the capabilities to meet the testing requirements of ETAG 004, ETAG 17 and MOAT 22.

We can test a range of ETICS, VETURES and render systems for use on masonry, steel and timber framed walls.
