The Insulated Render and Cladding Association (INCA) has published additional guidance on the installation of external wall insulation (EWI) designed to ensure that EWI systems are fit for purpose and installed to a high standard.
Following the publication of the INCA EWI Best Practice Guide in 2015, INCA has produced an updated version of the INCA Technical Guide on Fire Protection Requirements for EWI Systems, which aligns it with current British and Scottish standards.
The guide includes new guidance on legislation, regulations, standards, storey height, boundary distance, insulation fire performance and design considerations.
INCA has also published a new INCA Technical Guide to Mechanical Fixings designed to help specify the correct fixings for projects. INCA says many system designers rely on mechanical fixings to secure EWI systems to the building substrate, and reference should be made to the system accreditation to understand if this is the correct method.
The new INCA guide offers advice on how to identify the right fixings for different property types and is another essential resource for those involved in EWI.
Julian Taylor, technical committee chairman for INCA, said: “INCA and its members are committed to improving standards in EWI to the benefit of their clients by developing technical guidance and sharing best practice. INCA members are leading the way in EWI innovation and remain uniquely placed to deliver the highest quality for clients. These new and updated technical documents demonstrate that we are leading the way on behalf of the industry and cementsour place as the recognised trade association for organisations involved in EWI.”
