The next job in the attic is to create a ceiling.

The easiest and quickest way to make the ceiling would be to build a frame on the existing beams, insulate it with 150mm of rock wool, cover it with boards and paint it. But we decided we wanted to keep the 19th century features in tact, opting to keep the beams exposed.

At first we wanted to use some old wooden boards to clad the ceiling, but the boards we have a warped, meaning that we would have to put them through the planer many times to get a nice finish, which would have taken a long time. So we decided to stick to what we’re good at and render the walls with a clay plaster.

So the steps will be to first seal all the air gaps with bitumen paper, which will stop the wind from stealing the heat from the insulation. Next we’ll put in 50mm of rock wool. Then we’ll cover it with cardboard for added insulation/ air sealing. Finally we’ll plaster the wall, which requires a lengthy explination that I’ll save for the plaster blog post.

We tiled the bitumen paper down the wall starting at the top, so any drips or condensation would run down and out of the house under the eaves. We stapled it in place using scraps of cardboard as washers to stop the staples from ripping the paper. Finally I used tubes of bitumen in the caulk gun to seal the edges of the bitumen paper to the beams to air seal the spaces.

I like to take the long way round. 🙂

Maarja and Tinnu also plastered the chimney, which looks clean and bright with lime plaster, but still has natural textures and shadows after being applied by hand.
