Hi, I'm researching SIPS such as CarbonLite and Habitech as possibilities for a house in Sth Gippsland. Are there other brands? Any comments on cost compared to traditional wall/floor/roof building? I'm interested in terms of their insulating properties (if sealed thoroughly), as am keen on passive house principles, without going to certification levels.
Also, does anyone know if there is a triple glazed window manufacturer in Australia? And are windows with aluminium outside and timber inside, 'thermally broken'? thanks!
