Internal Wall Insulation

 

Retrofitting Internal Wall Insulation (IWI): Best Practice

On September 13th the Department for Business, Energy & Industrial Strategy released new guidance concerning internal wall insulation relating to Retrofit. The document discusses topics such as the benefits of such a measure, the materials, and the considerations to do with thermal bridging – along with many other relevant topics. 

This guide can be used to assess:

  • viability of internal wall insulation or systems
  • the design of internal wall insulation
  • the selection of materials including hygrothermal aspects
  • It also provides information on best practice for internal wall insulation.

Who is it for?

The guide is recommended reading for any parties undertaking internal wall insulation. Some sections have been written specifically for the retrofit assessor or surveyor, the retrofit designer or the retrofit installer.

The guidance is relevant to all installations of this type, regardless of whether it is being delivered under a government scheme.

The guide has been colour coded to highlight specific areas relevant to Retrofit Assessors, Retrofit Designers and Retrofit Installers.

Where Can I Read It? 

This new guidance was published by the Department for Business, Energy & Industrial Strategy and is available as a downloadable PDF.
