Hello
Quick query, we have a 1920 solid brick bungalow that has had a large extension added in the 50s (block work with 50mm cavity).
A lot of the pebble dash render is in bad shape so over the summer we are hoping to strip the dash and fit EWI with new render.
Question is, is it ok to have the cavity filled now then fit the EWI later? I assume to cavity must be filled/sealed to prevent air moving in the cavity?
Cheers
Neil
