External Wall Insulation
Retrofit and PAS 2035

PAS 2035: Is a Publicly Available Specification which is designed to provide a clear retrofit standards framework for the installation of energy efficiency measures (EEMs). The framework has been designed to raise standards and consistency in relation to both the design and installation of these measures and to ensure that they are appropriate for the property and will perform as expected.

It works on a “whole house” approach whereby the entire property is assessed and all appropriate energy efficiency measures specified together – including:

  • Hot Water
  • Heating
  • Lighting
  • Windows & Doors
  • Insulation (including EWI of course)
  • Micro Generation & Renewable

In this section we will be building up a library of information and doccumentation relating to external wall insulation and PAS 2035
