We are thinking of getting double glazed windows for our house.
I have heard that Lossnay would be better. (link below) Installation for my house is $3000 with 3-4 vents in each room plus lounge.
I had double glazed windows prices and its come up with close to $1600 just for one room.....excluding installation costs so that will be roughly another $500 on top.
So my question is has anyone got the any of the above and can recommend what is better?
