Support Straw Building: Donate Now!

Donate to CASBA’s efforts to promote straw building nationally through a straw bale construction code in the International Building Code (IBC) and the International Residential Code (IRC), and to funding research and testing for straw bale wall systems.

Donations help defray travel expenses to IBC and IRC committee hearings (where straw building advocates present proposed code or changes), and fund related computer modeling and straw bale wall testing.

For more information, see

If you are making a donation and would like to "earmark" it specifically for the code effort (or any other specific project), please indicate it in the Comments section below.

Thank you!
