Was just wondering if anyone had any comments generally on secondary glazing? Perhaps on particular products?
Specifically, I'd be interested in secondary glazing which is toughened K, and a balanced vertlcal slider.
One question I have is what is the difference between a balanced vertical slider and a vertical slider which is not balanced?
I've noticed the secondary glazing can have uPVC frames. Though if the point is to retain original timber sash frames and original internal timber surrounds, it seems to defeat one purpose if secondary glazing with uPVC frames are installed? Any comments on this?
Apparently the frames can also be made from aluminium and also hardwood.
