This Part of BS 5803 specifies requirements for the application of thermal insulation in pitched roof spaces in new and existing dwellings. It covers both the insulation of an uninsulated roof and the application of additional insulation to increase the existing standard of insulation. Insulation at rafter level is not included but advice on this type of installation is given in appendix A.

The standard specifies essential procedures and precautions to be undertaken, and makes recommendations to ensure an adequate installation.

It covers fibrous materials that may be substantially inorganic or organic and may be in the form of mats or loose-fill suitable for application by blowing.

It covers the following situations:

  1. an individual dwelling where the work is carried out by an insulation installer;
  2. a number of dwellings where the work is carried out by an insulation installer;
  3. an individual dwelling where the work is carried out without a contract.

NOTE. In all cases the clauses covering workmanship apply.

NOTE. The titles of the publications referred to in this standard are listed on the inside back cover.
