Internal Linings

New Year has come & gone, it now seems like a distant memory. Our focus over the last few weeks has been on internal partitions. In a typical timber framed house this is usually done with gypsum based plasterboard. Standard plasterboard is relatively lightweight and is easy to work with. The downside is that due to its low density, partitions lined with it can often feel flimsy and sound hollow – something my dad would call ‘cardboard walls’. We have decided to improve the acoustic performance and thermal mass of internal walls by installing woodfibre insulation between studs, and by using heavy lining boards.  Fermacell boards are made from recycled gypsum, paper and water and are twice as dense as standard plasterboard. This higher density should help moderate internal temperature peaks and troughs all year round. Another advantage of Fermacell board is its rough surface – it will be an ideal substrate for clay plaster skim layer.

It’s been great to have my brother coming over for a week to help out with the installation. With the linings on, we can now really start to visualise the spaces.

Roofing Pt2

This week’s weather has been kind enough to allow us install woodfibre boards on top of roof I-beams, and wrap the boards with windtightness membrane, held down by timber counterbattens. Larger timber battens will provide support for the corrugated metal roof. It’s good to have two layers of protection above the straw panels.

We have been tweaking the design of junctions between timber cladding and roof with Mike, and decided that it’s best to finish off installation of external woodfibre boards to walls and insect mesh to close off vented cavities before the corrugated roof goes on.

On Saturday Joyce & me finished off sealing the last charred cedar cladding boards, which was very satisfying to see. It’s now all stacked and ready to use.

There was a bit of excitement when a herd of escapee cows passed our site – I wonder if they wanted to have a peek at this straw filled passivhaus? 😉
