This Information Paper provides a broad view of the benefits and limitations of non-loadbearing hemp lime walls for those considering their use in construction projects.

Hemp lime is a low-carbon building material with good insulation properties and robustness. It is particularly suited to projects where the design calls for a rendered or rain-screened external finish, good insulation and minimal thermal bridges. It is most commonly used in conjunction with timber frames, but can act as a non-structural walling element for a variety of construction types, including lining masonry walls.

This is one in a series of five Information Papers and parallel case studies on low-impact building materials. The others cover straw bale, unfired clay masonry, cross-laminated timber and natural fibre insulation.
