Cellulose insulation

To be able to heat the house over the winter we needed to insulate the floor and roof. This we did by blowing 40cm of loose cellulose.

Put to bed for the Winter.

We bought some of the cellulose from a hardwear in Joensuu who loan out the blowing machine for no extra charge, we got the bulk of the insulation from a different cheaper supplier. We needed a more powerful generator to run the blowing machine so ended up hiring one out. After spending a week or so hand stuffing all the places that were difficult access such as under the walls and at the base of the roof section. It took 2 long days with from 3 to 5 people working, someone loading the machine Dennis on the end of the hose blowing the stuff and me running around preparing and hand compressing with the other helpers.

On the ground floor it was a simple job of blowing in between  the floor joists adding an extra 50% which is the compressed by hand. This extra 50% allows for settlement.

 For the roof insulation we did it in stages, fixing on a horizontal 1,2m strip of building paper with staples then filling that space from above, then fixing the next strip of paper and filling that space. Filling the space above the window was quite tricky as there is lots of extra pieces of timber framing in the insulation space. I went around later checking how well the cellulose had filled the space by cutting a hole in the building paper and stuffing in extra cellulose where needed.

Its a dusty job but someones gotta do it!

Thank you Dennis, Dominika, Andre, Emelia and Pjotr.
