Hey Building Folks!

I'm trying to build a tiny house without the use of any artificial materials; do you think traditional oilcloth might possibly work rather than house wrap? I'm considering putting it between Shou-Sugi-Ban siding and wool insulation.

Thanks for your input!

The spun-bonded nature of Tyvek is a distinguishing characteristic that you are not going to find in a woven material, no matter how the woven material is other-wise treated.  It is this spun-bonded quality that makes for excellent resistance to air infiltration, and using a woven material is most likely going to end up short in that department. 

So let me challenge you on your no artificial materials requirement.  Would it be alright to use an artificial material if it was on its way to clog up a landfill?  Would it be good if you could reduce waste somewhere else by recycling and reusing?  Because there are many, many mailing envelopes made of this same spun bonded polyethylene, and if you started collecting those and using sheets of them, it wouldn't be long before you had enough area to wrap a tiny house.  Polyethylene can be solvent welded with both acetone and toluene, so it might take a little experimentation to get the overlapping and gluing process down right, but you could make your own do-it-at-home Tyvek and be green in the process.

This is an interesting challenge!   Maybe one layer would not be enough, but if you had several layers of oilcloth, this might work?  Like a traditional thatched roof of reeds.  If the layers are thin the water would soak inside the roof, but since it is made of thick layers, the water runs off the reeds and the inside of the roof stays dry.

This is an interesting idea!

Hi John, thanks for your innovative idea! However, this will most certainly not work for my project. The biggest reason for attempting this project is my health: I have a severe toxin sensitivity. I'm attempting to discover if my general health will improve if I live in a toxin-free environment.

Interesting idea! I like it. If I try this, I'll let you know how it turns out!
