Klober has updated its ‘Elimination of condensation in roofs’ CPD presentation, which examines how to provide ‘breathing roofs’ to prevent the formation of condensation in the roofspace.

Certified by the Construction CPD Certification Service, it covers the use of vapour permeable and air-open underlays in cold and warm roof specifications.

It features specific reference to the requirements of BS 5250 Code of Practice for control of condensation in buildings.

The presentation also discusses topics such as new build and refurbishment issues.

Comment is provided on insulation between and over rafters, air and vapour barriers, airtightness accessories and BBA certification.
