July: insulation, ceilings, green roof

The house is now weather proof. The outside cladding, guttering, windows, sealants, waterproof edging on exposed roof beams have all been finished.

Most of the ceiling frames are now complete and the current job is mostly fixing the wall insulation and frames. Some ceiling plasterboard sheets have also started going up. These are made of gypsum but with 30% less embedded energy of regular plaster board due to recycled content – from  Yoshino – Tiger brand.

The upstairs deck has also been sealed and prepared for a green (living) roof. This entails 5 main layers – waterproof sheet (I used heavy duty pond liner), a layer to hold moisture (old carpet), light stones to assist drainage, a membrane to prevent roots passing through,  and finally soil for the grass or sedum. For details and photos on how to make a green roof you can visit 2 galleries I have of previous green roofs I’ve made: 1st green roof 2010, 2nd green roof 2012

NEXT month: Solar PV system and stove chimney to be installed. ceilings to be finished, and if time, bathroom floor and shower unit.


About ifd66

From UK and living in Japan. I am very interested in sustainable development and in general ecology and conservation issues and solutions. Finished building a low impact family house in Shiga, Japan in 2013 and am now focused on using permaculture to develop our plot of land into a more sustainable, productive, and attractive space. My hope is that this blog is useful to those interested in similar issues and way of life.
