The art of insultation

We spent a couple of months doing the underfloor insulation and this is the result. We used polystyrene panels which are cut to fit joists and concertina cut to allow a bit of compression. They then fit snugly without the need to nail them in. The panels come in packs of 12 and we were 1 short so I did a patch job with leftover bits on the very last bit. We could only get 24 panels in the car at a time which is why we've been gradually working on it rather than doing it all in one go.
The title of the blog entry relates to an amusing typo at the Placemakers DIY store where we went at least once a weekend for the past 2 months...

We have a proper basement, half of it is well above head height and most of it allows you to crouch-walk, only a small proportion requires the awkward shuffling on your back to do the insulation. This is not accident but design on our part - we were specifically looking for a house with an accessible basement to allow us to insulate it (saving 15% of heat loss, apparently)...
Total cost of the underfloor insulation for our 130m2 house was $1088 (but there is a part that can't be insulated) so it might be around the $1200 mark for the whole lot if we could do it all.
So we look forward to a much warmer winter next year :-)
