What R-value do straw bales provide?

Straw bales provide R-30 to R-45 per 18-inch bale depending on orientation and density. This exceeds code requirements in most climates with a single bale wall.

Are straw bale houses fire-resistant?

Yes, densely packed straw bales are highly fire-resistant (>1 hour) due to limited oxygen. Loose straw burns readily, but bale compression prevents rapid combustion.
