- Perforated (web perforated):

With perforations to the mid-section of the web of the profile. With tissue faced acoustic batts set within the trough of the deck, the web perforations allow the deck to provide sound absorption. Consult manufacturer for details on perforation pattern availability. The web perforated deck will require filler blocks bedded in sealant to the underside and topside to continue the air barrier/ vapour seal - consult manufacturer for further details.
