Comparing Prices of Insulation Batts

I was looking at the prices of thermal/acoustic insulation batts for walls or ceilings. Checked prices online between Bunnings, Masters and another trade store. Since I compiled a list, I thought I may as well share it, in case it is of help to anyone else. Not comprehensive, and only shows the details I was interested in. The price per square metre obviously doesn't take account of R values and thickness of the batts. (I didn't record thickness in my table, although usually you can tell from the descriptions.)

I was particularly interested in trying the polyester batts, which are more expensive but appealing if they don't have the same kind of glass fibre safety issues. Also looking at acoustic batts, and how much more expensive they were compared to normal batts.

Mutant Freddo Frogs

Discovered some more beneficially mutated food today :) Kids had some Freddo Frogs that were double-thickness! Only discovered after some bites already taken, but combined weights of both headless frogs still 32g (normally 10g each!) :P

 
Right photo is comparison with normal Freddo :D

Creamy Chocolate Bonus Deck = Beneficial Mutation?


The other day I opened my lunch box to find an interesting surprise. I had some Arnott's Creamy Chocolate biscuits in there (favourites since childhood!), and discovered that one had an extra deck (see photo below next to a normal one). The first time I've seen a beneficial mutation in real life. Maybe evolutionary theory could be possible, haha!



Plants for sale from our garden!

Well, we're going to extend out the back of our house, and need to get rid of the garden. So I've put up some pictures of plants there, if anyone wants to buy some :)

2010-07-08: My ride home

This is the plane that would take me back to Australia :)

2010-07-08: Some views of the big city

Instead of just waiting at the airport for a few hours, I decided to take the fast train to Hong Kong CBD, and have a quick look around. Here are a few random photos. When you return the same day on the train, you only have to pay the one-way fare, which was neat. They also had internet access on the train, which I thought would be great, but I found out you had to have an account with the local provider to use it. Oh well!
