Pavatex Pavaclad

NBT 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 NBT 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 air tightness layer and vapour control in a breathing wall construction. Internally we recommend a service void behind the plasterboard for effective air tightness control and easy service alterations.

System Application
NBT 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 racking board then also becomes the air tightness layer and provides secure mounting for services. This means that the air tightness can be assessed before installation of final finishes such as plasterboard.
The significantly lower cold bridging through studs and y-values(psi) means that the Pavaclad system outperforms traditional timber frame systems. The insulation layer is continual, including into reveals and returns.
With certain cladding materials, multi occupancy applications require fire stops between units in the external cavity. Contact NBT for further details.
