SPECIFIC RECOMMENDATIONS FOR AIRTIGHTNESS AND INSULATION OF THE INSTALLATION
To remain airtight in the long term, the ductwork must be mechanically strong
(attachment between duct elements) and correctly supported. Failing this, the sag may
eventually crack the mastic.
Any duct carrying hot air that is outdoors or in an unheated volume must be insulated
with 50 mm of glass wool or equivalent.
