i bought it fom bunnings as a 5.95metre handy pack for $86.00. had to order it as they only had 20 metre packs . its new and there seems to be a demand for it. You can cut it with scissors and use a staple gun to attach it to timber.

Another product that I can very highly reccomend is a heat reflective paint from Global Coating Solutions. A500 Insulpaint Tropical. We recently painted the roof of our coffee vending cart, and in the midday sun, with an air temp in the mid 30's, the steel roof is only warm to touch. The secret is tiny balls of glass within the paint that reflect the heat away from the steel.
It's not cheap, about $300 for 20 litres.
I'm thinking of wacking a coat on my OTA, and see if it brings the cooling time down.
