Dear SR, I meant to use insulation and double glazing as two separate terms. double glazing windows means that there are two glasses used instead of one,in the frame, with slight gap between the two, the layer of air trapped between the glasses prevents heat/cold from affecting the room by conduction significantly. By Insulation, I meant thermal insulation in roof or walls, it may reduce temperature effects by few degrees. |
