Is there any difference between stacker doors and lift & slide doors? If so, which would be best for acoustic and thermal insulation in a double glazed unit?
Also, how much difference is there between stacker doors and bifolds for acoustic and thermal insulation?
And has anyone used Easy Windows in Sydney? I like the look of their windows but on their website they say "The glass [low-E] is typically used on North facing walls in Australia and helps a home retain warmth by allowing long energy waves (heat) to enter the house through the windows and doors and prevent these waves leaving. Good for warming cold houses."
This doesn't seem right?? I was thinking we would use low E in double glazing for west facing windows that got direct afternoon sun in summer, to prevent, not allow, the heat coming in.
