I am building a large east/south facing deck with a roof - 4.5m deep. It gets a wonderful morning sun in winter, but unfortunately blocks the warmth from the house. In summer however it is perfect for blocking the morning heat (Brisbane). The roof will probably be the foam core sandwich panel as it can cover the span without support and is not far off the cost of roof/frame/insulation/lining.
I have seen some big panel type louvres advertised here and there that I could open in winter to let the sunlight in, but close in summer. When I got a quote a 2.5mx4.5m panel was $12,000. The whole roof is only $7000 for sandwich panel. Ouch. Has anyone seen any more cost effective alternates to let the winter sun in, but block the summer heat?
I know it's a "roofing" discussion, but this tends to be where the "deck" discussions end up.
Thanx
Paul
