Hi , can anyone answer me a question , i remember when i had my double
glazing fitted some years ago, which is still fantastic , but i remember the
guy from the double glazing firm said that if a window size is over a
certain size , then the cost can go up quite a bit because you have to use
toughened glass , thankfully i did not need any on that house , but we've
been looking at another house just today and some of the windows look tall
about 2.5 meters high by about 1.3 meters , does anyone know the regulations
for toughened glass used for double glazing over a certain size? is it based
on its overall meter squared or based on its heights or width only ???
if toughen glass is needed to be used , how much would the cost go up by
based on standard commonly used glass for double glassed units?
