I want to replace a couple of my windows which are misted up. So in order to avoid appearing a total amateur[1] I need to know -
How to order the units, ie are they specified as total thickness of the unit or as the separate thicknesses? ISTR hearing that some windows have a 6mm and a 4mm, and some need two X 6mm. Also that some have to have toughened glass.
And how many kinds of the rubber seals are there, will I need to provide a sample?
Any links to good DIY sites or suppliers would be appreciated.
TIA
