I've been buying it for about $36 per sheet or so. It's 3.6m long x 900mm wide so I need 4 and a half sheets per 4M bay wall. So about $160 per bay.

The only downside is it can be bloody heavy and awkward when your trying to stand up and position a sheet by yourself.

The pine lining boards and corrugated iron just nail and screw straight to the yellow tongue walls. It does seem to knock the heat and noise down a fair bit. I also like the added security. It's fairly easy to pull a sheet of tin off a shed to break in but when confronted with the chipboard flooring on the inside it makes it a bit tougher/slower/noisier to break in.

BTW the next update to the shed is a 3KW worth of solar panels on the roof. Should be going on in the next few weeks.

Cheers
