Aluminium Double Glazed Windows

Warmer Home, Dryer Windows

It’s generally accepted that 51% of energy is lost through single-glazed windows of a well-insulated home – the more glass area you have, the higher your energy loss. Regardless of how much glass you have, retrofit double glazing your existing aluminium windows gives a cost saving of between 30 and 40% over installing new windows.

Over the past 30 years in the glazing industry, Thermoglaz has pioneered the development of specialist extrusions for double glazing aluminium windows, allowing homeowners improved warmth, dramatic noise reduction and substantially less condensation. Now at last, you can enjoy your favourite view more comfortably in any season with aluminium double glazed windows
