This is also nothing new, straw has been used as an insulation material for a very long time, even in "modern" buildings.
It's just nowhere near as effective as glass wool, for example.
Is that the same as fiberglass?
Also "forbidden cotton candy"
Kinda but not really, they're both made from glass fibres, but are a very different product that serves a very different purpose. Fibreglass typically comes in a flat cloth, and is used with resin to create something structural.
In the US we generally use fiberglass to mean both. But specifying glass wool would be more clear tbh.
Would also match nomenclature with Mineral Wool Insulation.
Yep
I worked on a few buildings where they used straw balls lenght wise. They had meter thick walls and it's very efficient. One of them only had a tiny wood stove
When you have a meter... I think anything will work as insulation
I mean at that point a meter of air gap alone would be amazing insulation.
just an air gap is not that good as convection will move the air around decreasing its effectiveness. Most insulation is just a way to try to keep the air in place while the air is doing the actual insulation
Thats not efficient in terms of space though, you'd lose a lot of floor area that way.
Grand designs did an episode on the construction of one. It has a beautiful smooth interior look once its rendered
Fiberglass insulation is cancelled
It also doesn't rot or burn.
It can be used as structure, not just insulation, if compressed right.
