I live in Canberra and have nice open mountain views in west direction. So I would prefer to have windows on west side as well. Our cold winter makes double glazed windows a must. Otherwise, it will be unusable after sunset. How about external blinds blocking radiant heat during day time ? Companies like Luxaflex claim 90% efficiency. Is that so and are there any cheaper ? 10-15% per floor area of the room sounds rather small, it's only 3 sq.m. of windows. What walls should we install with high EER ? A view to the Brindabellas? My family still live there. 12-15% is enough if they are north facing. They will get sun for most of the day. For Canberra you might go up to 17%. The problem with too much east or west glass is the overheating issue in summer and the lack of direct sunlight for half the day. The only way to shade them 100% is by using vertical shades because the angle of the sun will still get in under long eaves. This will then block your views. You can try combining it with a reflective tint. There are also see-through reflective blinds. External blinds are more effective than internal coverings for blocking radiant heat. i think option 2 is much better with easy access to the garden without having to walk through the new sunroom which makes it a better room for guests and TV .a simple… 2 8192 Depends how much direct sun it gets. Is there any shading (eaves or trees)? If the sun hits a window directly it doesn't matter too much if it's double or single… 1 12635 Well you won't get cooked by the afternoon sun when sitting out on the balcony on a summers afternoon but you won't have much to look at besides the neighbours… 4 3749 |
