Triple glazed windows


Triple glazing is the latest innovation for the highest energy efficient window installations possible.

Triple Glazing windows from Osborn Glass represent the very latest that the glazing industry has to offer. Triple glazed windows have the same great looks as double glazing, but are far superior in terms of thermal efficiency – approximately 60% more thermally efficient than standard C-rated double glazed windows, and 40% more efficient than standard A-rated double glazing – therefore saving you hundreds on your heating bills.


Triple glazed windows also provide improved home security, by adding another barrier to intrusion as well as strength. Osborn Glass triple glazing windows are available as Casement Windows, Tilt & Turn Windows and Georgian Windows, in a variety of colours and woodgrain effects.
