Why is insulation important?

Insulation is one of the most crucial parts of the building process. Not only does it serve to protect us against the elements, but the right insulation will drastically reduce your utility bills by maintaining an ideal indoor climate, minimizing the need to continuously run the heater during cold seasons and the A/C during warm seasons.

How many points does straw bale insulation have?

Straw Bales score 18 points, tying Air Krete GREENsulation, but losing to the tie due to Air Krete’s accolades, reviews, and status as a specific product that can be regulated and reviewed. Of the One Community Scoring Priorities, this product was tied with the highest score for Sustainability (7 points), but has the lowest score for DIY (-1 point). The only categories in which straw receives negative points are density, complexity and ease of installation, and additional costs. Straw bale construction has been gaining traction as a sustainable way to insulate and construct your home. Closely stacked straw bales sealed with an earthen plaster provide an excellent barrier between you and the elements. We’ll also be open sourcing complete DIY straw bale construction details when we construct the Straw Bale Village. Note though that straw bale construction is really only an option for new construction rather than a replacement for your current insulation. Additionally, this product is best suited for warm, arid climates, because in humid climates and in heated homes the straw is susceptible to condensation. The cost and availability of straw bales nearby is another important variable factor.

Traditional commercial insulations can contain VOCs, urea formaldehyde, and countless other toxic chemicals that can cause adverse health effects. Even in the market of sustainable “green” insulation, there are still some products containing hazardous materials such as methylene diphenyl diisocyanate, or MDI, a synthetic chemical linked to asthma, lung damage, and even death.
