Pavaclad
System Description
Avilion’s Timber Frame Pavaclad System is for timber frame buildings externally finished with any type of cladding including facing bricks, rendered blockwork, timber boards or shingles, tile, terracotta claddings, metal sheet etc. Pavaclad systems use Pavatex woodfibre boards over the outside of the frame in a continuous layer, with the racking board on the inside of the structure. The racking board acts as the airtightness layer and vapour control in a breathing wall construction. Internally we recommend a service void behind the plasterboard for effective airtightness control and easy installation of services.
System Application
Avilion’s Timber Frame Pavaclad System can be used with any conventional timber frame design, provided that the racking board is fixed on the inside of the frame rather than the outside. The same limitations apply as to all timber frame applications. With certain cladding materials, multi occupancy applications require fire stops between units in the external cavity. Contact Avilion for further details.
