I thought I would use WERS http://forum.homeone.com.au to browse for suppliers
of thermally broken aluminium windows and I am getting surprised by almost zero results:
- show all manufactures + casement/awning + thermally broken => gives: 1 (one) result with Uw = 3.3.
- show all manufactures + sliding window + thermally broken => gives: 0 (zero) result.
Does this mean "thermally broken aluminium windows" do not exist in Australia
or is the WERS not.... (that) relevant/representative of the actual market?
Would appreciate pointers/suggestions.
