Straw Bale - An introduction to low-impact building materials

Straw Bale - An introduction to low-impact building materials

This Information Paper provides a broad view of the benefits and limitations of straw bale for those considering its use in construction projects. Straw is a renewable material offering good thermal insulation properties and a much lower environmental impact than many current mainstream construction materials.

Straw bale is very suitable as infill insulation for timberframe buildings with either an external render or timber rainscreen finish. Straw provides a vapour-permeable wall construction using a locally sourced, low-impact material, although it does need careful detailing and construction to avoid the ingress and retention of moisture.

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.
