In many parts of the world, straw is used to bind clay and [[concrete]]. A mixture of clay and straw, known as [[cob (building)|cob]], can be used as a building material.  There are many recipes for making cob.

When [[Baler|baled]], straw has moderate insulation characteristics (about R-1.5/inch according to Oak Ridge National Lab and Forest Product Lab testing).  It can be used, alone or in a post-and-beam construction, to build [[straw-bale construction|straw bale houses]]. When bales are used to [[Building construction|build]] or [[Thermal insulation|insulate]] buildings, the straw bales are commonly finished with [[earthen plaster]]. The plastered walls provide some [[thermal mass]], compressive and ductile structural strength, and acceptable fire resistance as well as thermal resistance (insulation), somewhat in excess of North American [[building code]]. Straw is an abundant agricultural waste product, and requires little energy to bale and transport for construction. For these reasons, straw bale construction is gaining popularity as part of [[passive solar]] and other [[renewable energy]] projects.<ref>[http://www.earthhealing.info/strawbale.pdf The Straw Bale House: Suitability for the Eastern U.S.]</ref>

Wheat straw can be used as a fibrous filler combined with polymers to produce [[composite lumber]].<ref>{{cite web| url = http://biomassmagazine.com/articles/1367/adding-value-to-wheat-straw/| title = Adding Value to Wheat Straw By Anduin Kirkbride-McElroy. Biomass Magazine, 2007}}</ref>  

[[Enviroboard]] can be made from straw.

Strawblocks are strawbales that have been recompressed to the density of woodblocks, for compact [[cargo container]] shipment, or for [[straw-bale construction]] of [[load-bearing wall]]s that support roof-loads, such as a "living" or [[green roof]]s.<ref>{{cite book | last=King | first=B. | title=The New Carbon Architecture: Building to Cool the Climate | publisher=New Society Publishers | year=2017 | isbn=978-1-77142-256-7 | url=https://books.google.com/books?id=3ocuDwAAQBAJ&pg=PT95 | access-date=January 1, 2019 | pages=pt95-96}}</ref>
