house building insulation ideas

:chitown:Hi, I am not to sure if anyone has heard of using dry rice husks as insulation when building a new house in thailand.
Well from the investigations I have done via the web it seems a no brainer to use this very cheap and very readily available (waste product) for insulating your new or even existing home.
You can purchase it by the truck load from any rice growing district(i know pretty hard to find in thai) for not much more than the few hundred baht of the delivery.
after all it is WASTE product thais have no use for it other than maybe to use it as fill.
Tests have proven rice husks to have a high silica content and to be inflamable,(will not burn)insect and vermin proof,mould proof, have excellent thermal properties also,what more could you want!!!...insulation R rating higher than fibre glass insulation and the like,it works the same as other insulations but to to a higher degree of efficiency.

Not taking the pish or anything, but is this stuff flammable in this form?

Interesting concept though:

It seems it is.

Don't they use rice husks to bake bricks in some parts of Thailand? That would mean it does burn and probably quite well.

agreed again.

We burn our rice husks to make fertiliser

surely a perfect nesting home for bugs,vermin etc,but people do use straw bales for insulation in eco type houses.

The winter smog problem in the north started just after Theytim arrived in country.

I think he is refering to the rice hulls that surround the grains themselves, not the rice straw that is left over when you harvest the grain.
Apparently he is correct in that is difficult to burn and is high in silca content. Interesting read here

Doh!

:tieme:

Let me see. Thai husks with Somchai doing the wiring. I think that I will pass on this energy saver.

we only use them in the Veg garden as a good fiber source to add to the soil, young lad sells them of the back of a cart,

they will break down eventually back to dust.

Sounds much better than burning them to distribute the ashes. Should make the soil structure better.
