I am looking for advice on replacing very old Aluminium Double Glazing windows.
I have had 2 double glazing companies give quotes and "advice". Both members are registered with GGF and FENSA.
One company extols the virtue of Aluminium Double Glazing for its toughness, durability and looks.
The second company said that Aluminium windows must be put into hardwood frames to allow the aluminium to "move" during different weather conditions. If fitted directly into the brick, there is a chance that the glass may crack. This company did not push their aluminium product, so I was a bit suspicious about the remarks.
Can anyone tell me whether fitting Aluminium windows without a hardwood surround is a problem and if so why?
Thanks
Phil
