Great insulation – Straw bale walls provide at least R30 insulation, which can greatly reduce energy used for heating and cooling. A typical 2×6 stud wall with maximum fiberglass insulation is rated R19. What is an R-value?
Good for the environment – Straw is an agricultural waste product and straw bale building is a great example of upcycling. What is upcycling?
Good fire resistance – Straw bale walls have a very good fire rating: 1 hour for earth plastered walls, 2 hours for cement-lime plastered walls. A typical stick-built, drywalled wall has a 30 minute rating. What is a fire rating?
Less materials – A plastered bale wall replaces the insulation, the drywall and the paint usually used in a conventional wall, and can reduce the wood needed for framing.
Better sound quality – Straw bale walls provide excellent sound insulation and have a positive effect on interior acoustics.
