Paragraph 3.4 was withdrawn and replaced by the following: 3.4 Where the original windows were fitted with trickle ventilators the replacement windows should include them and they should be sized as set-out in paragraph 3.6. It would be good practice to fit trickle ventilators (or equivalent), with accessible controls, in all replacement windows to help with control of condensation and improve indoor air quality.

The opportunity was also taken to make consequential changes, correct minor errors in the text, and make clarifications in paragraph 1.4 and Annex B.
