In-Depth Information
Low-density hempcrete used as roof insulation.
Cold bridging can be minimized by careful detailing of the rafters, such as by using
battens and counter-battens, and airtightness over the top of the hempcrete insulation can
be provided either by a vapour-permeable membrane or by the use of tongue-and-groove
water-resistant vapour-permeable sarking boards, which have the advantage of adding ex-
tra insulation.
