Wow, they insulated the ceiling in the old way. Already the timber bent

I took up a house in the village, I want to make a new extension, and demolish the old one. I started from the roof, so that when you break down the walls, the slate doesn't come flying over your head.

The unexpected decision of the builders

When I removed the slate from the right wing, I saw such a picture, clay was piled on top of the boards, I looked closely, interspersed with sawdust.

Everything is clear, the collective farm had its own sawmill, so the old-fashioned way was used, as a heater, only the bobble came out. Shingles were nailed to the boards, and plastered, the boards themselves were nailed to the timber, and clay on top.

Moreover, the boards were kept only on the timber, the edges were adjacent to the wall without support.

There was little sawdust in the clay, it weighed decently, all the load fell on the cross-beams, so it bent.

And what insulates the ceiling in the house?

Okay, what's on the house itself? Climbed into the attic, and saw a layer of coal ash, fragments such as expanded clay, light and dry, well, at least not clay. Probably, it was the former owners who insulated themselves.

I remembered that they sell algae mattresses in Simferopol, kamka is called. I saw them in bulk on the banks of the Azov, why weren't they used, probably there was no industrial procurement before, only privately. So it goes. Tomorrow I will knock down the walls and try to save the stone come in.
