What is double glazing?
Get a QuoteDouble glazing uses two panes of glass separated by a sealed air or argon gas gap. This gap acts as an insulating barrier, preventing heat from escaping and cold from entering. Our double-glazed windows achieve A++ energy ratings — the highest standard available — helping to significantly reduce your heating bills.
