The Insulation That Grows Back FOREVER. Why Did Big Construction Bury It?

The Insulation That Grows Back FOREVER. Why Did Big Construction Bury It? The insulation in your walls is failing—not because anything went wrong, but because it was designed to. Behind most drywall sits a product that slowly compresses, loses the air pockets that made it “efficient,” and quietly turns into your next renovation bill. This video is the story of the insulation that *grows back every year**: straw bale construction. It’s cheap, local, high-performing, vapor-permeable, and—when plastered—can outperform conventional walls in both **R-value* and **fire resistance**. So why don’t builders offer it, banks finance it, or insurers like it? By the end, you’ll understand how a better material gets “buried” without a single villain: codes written around standard stud bays, permitting systems that punish anything thick and unfamiliar, insurance categories that don’t track real test data, and a post-war construction model built for speed, standardization, and repeatable profit. 00:00 The insulation that’s designed to fail 00:49 A 1903 house that never replaced its “insulation” 02:20 The industry’s origin story vs the real history 03:00 Ancient insulation: reeds, mud brick, and trapped air 04:51 Medieval walls and why “primitive” worked 05:15 Nebraska’s straw bale breakthrough 07:32 Why straw bale works (the simple physics) 09:22 Strength: plaster isn’t cosmetic, it’s structural 10:06 Fire: why plastered straw walls don’t burn like you think 11:24 “Breathing” walls vs trapped moisture problems 12:59 The real reason it vanished: convenience and system lock-in 14:59 Codes built around 2x4/2x6 walls (and what that excludes) 15:27 Appendix S and why most places still don’t adopt it 16:19 Insurance, premiums, and the “non-standard” label 17:11 Mortgages and why financing becomes the real barrier 19:24 Oak Ridge testing and the R-value reality 20:33 Intertek fire tests and the numbers nobody markets 21:29 UK & France: when standards catch up to data 23:26 How hard it is to change a code system 24:28 Real projects proving it at scale 25:09 Bale raisings: building walls in an afternoon 26:00 The true barrier: permitting, not performance 28:32 What you do now that you know it exists #StrawBale #NaturalBuilding #GreenConstruction #PassiveHouse #BuildingScience
