Within the current build environment, it is essential that we assess External Wall Insulation Systems (EWIS), in particular, focusing on their ability to resist wind load and prevent installation failures.Although the thermal performance is the more important feature for users when considering to install EWIS in new or existing buildings, it should be stated that the structural stability of the system shouldn’t be overlooked.
With the growing market for EWIS, the BBA is working with the UK construction industry to improve its design, detailing and installation, including the specification of ancillary components, pre-installation procedures, the quality of work on site, and site surveys. Furthermore, we are also working alongside suppliers, installers and consumers to offer guidance and support on EWIS behaviours that might lead to unintended consequences from poor fittings.
Read our latest Technical Case Study, which examines the potential issues and unintended consequences of EWIS design concerning wind-load resistance.
