The first of 3 guidance documents scheduled for publication in 2024 this comprehensive industry best practice guide focusses specifically on EWI systems incorporating a render finish and defines the installation process, standardises common details, and provides useful information on the materials and components that make up a finished system.
It covers all aspects of external wall insulation including:

- Overview of different construction methods
- Installation methods and processes
- Standard detail drawings
- Condensation and damp
- Project completion
- Post installation maintenance
Designed to support all sectors of the industry (new build, refurbishment, domestic and non-residential), the new INCA best practice guide defines the recognised standards required to achieve optimal thermal performance and to ensure the highest quality of installation and aesthetically pleasing results. It is also intended to help and inform specifiers, main contractors, and clients in the correct choice of system for their projects.
