13mm sheathing board to provide racking and enhanced vapour transfer for timber frame and conventional construction.
Panelvent DHF is a 13mm square edged sheathing board designed to replace OSB and plywood as an external lining board. With market leading water vapour resistance values, this board allows the designer the freedom to design breathing structures, free of the risks of interstitial condensation.
Panelvent DHF is a structural MDF.RWH fibreboard manufactured in accordance with EN 622-5:2004.
Panelvent DHF sheathing board has been developed to combine high racking strength and durability under service class 1 and 2 conditions.
Panelvent DHF is used as a vapour permeable sheathing board for the timber frame construction industry and as an alternative to the more traditional OSB and plywood. It comes into it's own where vapour open (breathing wall) construction has been specified.
Panelvent DHF is designed to be used on the outer face of insulated wall framing due to it's high vapour permeability and high strength. We recommend it's use with OSB sheathing and/or vapour check layer on the internal face however the wall make-up must be checked by a qualified person to ensure condensation does not occur. In many situations the application of a breather membrane is not required, unless in areas of severe exposure, where rain screens or timber cladding are to be used or where required by the NHBC or the local authority.
When used in timber frame construction, Panelvent DHF sheathing boards must only be used where there is a fully vented cavity.
