Browse Forums Windows & Doors 1 Mar 29, 2011 5:54 pm Hey there. I am wondering whether anyone out there can answer my query please. Basically I am thinking of putting in 2 sets of tri-fold doors at the corner of the south facing rear corner of my house and do not know whether to put double glazed doors in or not. The house does have some insulation but it is not fully insulated. Basically insulation in the house is in the room where the proposed doors will be and the adjoining room only on both the internal walls and external walls. We are unsure whether getting double glazed doors without having the whole whole house insulated will defeat the purporse of having them as heat will still escape through the other windows in the same room (which isn't double glazed) and also through the rooms in the house that don't have insulation. There is a difference in cost naturally, but we want to do what is right both for heating and cooling and cost effectiveness for our bills down the track. What we don't want to do is waste money on double glazing if it will not have an affect. If anyone could give us some indepedent advice that would be brilliant. Thanks so much. Kind regards Re: Double Glazing 2Mar 29, 2011 6:05 pm Windows loose (or gain) heat faster than walls. As the windows face south west they will get minimal benefit from the sun in winter so they will you will get increased heat loss in winter. as you are unlikely to have heavy curtains shut during the day double glazing will definitely decrease the heat loss in this room. In summer you will gain some heat over your current situation with double glazing. the increase will not be as bad with double glazing. The Harder You Try - the Luckier You Get !

Re: Double Glazing 3Mar 29, 2011 6:11 pm Cheers thanks for that. Sorry just to confirm, do you mean the double glazing will bounce the heat away from the house in summer or are you saying that it will stay inside? Just not sure what your summer paragraph means. Thanks again though. Really appreciate it. Re: Double Glazing 4Mar 29, 2011 10:21 pm Rod12 Hey there. I am wondering whether anyone out there can answer my query please.

Kind regards Double glazing any window or door has the same effect of saving energy whether the house is fully double glazed of not. It will keep heat in in the winter, but will have almost no effect in keeping summer sun out. For that you need to add low-E.

Double glazing is indeed an energy efficient option, it may be a little costly...but you actually benefit in the long run. It's long lasting, and depending on the framing you choose, some of them can get really stylish. This is one of the reasons I decided to go overseas for my double glazed windows.
