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.

Test areas related to ETICS


  • Performance after hygrothermal cycling
  • Colour change measurements after UV exposure

Energy efficiency and thermal performance

  • Thermal transmittance (U-Value) (guarded hot box_
  • Thermal conductivity and resistance (heat flow meter)

Hygrothermal testing

  • Heat/rain and heat/cold cycling (ETAG 004 environmental chamber)
  • Heat/spray and freeze/thaw cycling (MOAT 22)

Mechanical testing

  • Resistance to soft body impact
  • Resistance to hard body impact
  • Perforation test
  • Resistance to pull through of fixings
