Browse Forums Windows & Doors 1 Dec 08, 2012 2:14 pm Hi, We are designing our house and would like some opinion about the glass type to use between the living room and sunroom. Currently we plan to have double glazed windows and doors for the whole house. In our design, we have a sunroom "attached" to the north side of the living room and we plan to have a 6 meters sliding/bifold door in between to separate the two areas as we only intend to use normal glass and polycarbonate sheet for the sunroom. Is there much benefits in using double glazed glass in this case or a single glazed glass will work just fine? Re: Glasses between living room and sunroom 2Dec 08, 2012 4:20 pm You need double glazing. Just the size of the air gap in the double glazing varying a few millimetres makes a big difference, if that gap is increased to 2 metres (the distance between your sunroom and your living room), the heat loss will be large.

Ed Thank you Ed. I thought the sunroom will act like a big buffer zone and hence will reduce the rate of heat loss. Didn't realise it doesn't help much. Initially I was more worry about the heat trap by the sunroom going into the house during summer time.. If you don't mind I have another question about the use of glass and polycarbonate in sunroom. If insulation is not an issue, can we use polycarbonate sheet rather than glass for the sunroom wall since polycarbonate sheet is much stronger than glass? Most of the sunroom design I saw only use polycarbonate sheet for the sunroom roof. 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 12666 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 3755 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 8227 |
