How it's done.
Bundles of straw, bonded with stainless steel wire, are laid layer by layer along the entire surface of the roof, starting from the bottom of the ramp, attaching to a wooden crate.
Then the roof is leveled and "combed" with the help of special scrapers.
Trim the edges.
And then cover the straw with a special refractory and waterproof substance. The process takes from several days to several weeks.http://www.liveinternet.ru/users/4386710/post352896906/
