At face value, an improvement in terms of heat loss through glazing from 1.1 W/m²K to 0.6 W/m²K sounds like an improvement worth paying for.
Tinted/ pigmented interlayerA coloured plastic or resin sheet between two or more panes of glass.
Additionally, laminated or thicker glass on the secondary pane can further enhance sound insulation.
DormerA space which protrudes from the roof of a house, usually including one or more windows.
This causes any unstable nickel sulfide inclusions (imperfections that may cause spontaneous breakage of the pane) to expand disproportionately to the glass, making the glass break.
If your double glazing has condensation on the inside between the glass panes, it’s not functioning as it should.
Using the figures mentioned above as a guide, this will depend on your own property situation – but in most cases, it will be many years before the glazing ‘pays for itself’.

Investing in triple glazing is often worth the cost in the long term, as the extra pane of glass can increase your home’s energy efficiency and result in cheaper heating bills.
Both double and triple glazing feature glass panes set in parallel, with a cavity filled with argon gas to provide insulation.
