What choices affect the price?
When buying thermopane glass, you have a number of choices to make:
Choice 1: Thickness of thermopane glass
The thickness of thermopane glass differs for exterior glass and interior glass. Outside glass is usually thicker than inside glass because it needs more protection from the weather and from burglary. If you want to know what thickness suits your home, it is smart to get advice from a glazier. Below is a price indication of the various thicknesses of interior and exterior glass.
| Thickness of exterior thermopane glass | Thickness of interior thermopane glass | Average price total window per m2 incl. vat, mounting and materials |
|---|---|---|
| 4 mm | 4 mm | £ 42 |
| 5 mm | 4 mm | £ 45 |
| 6 mm | 4 mm | £ 50 |
| 6 mm | 5 mm | £ 52 |
| 8 mm | 5 mm | £ 64 |
| 8 mm | 6 mm | £ 66 |
Choice 2: Install vents
When windows are inadequately insulated, condensation occurs as a result. In addition, a cold flat also causes cold radiation. Ventilation grilles ensure dry air in the house so nothing rots and mould does not develop. Ventilation grills are also beneficial when the windows cannot be opened and you still want to get some ventilation. By using ventilation grills, you save energy costs because dry air heats up faster. A small ventilation grille costs on average £15 and a larger one costs on average £60.
Choice 3: Different options in terms of colour and design
When you use thermopane glass, you can also combine it with different techniques. With so many techniques and new possibilities, fun and energy-friendly solutions can be devised. Think of incorporating a colour into the glass. Digital printing technology is used, allowing you to process colours and images on insulating glass. So look carefully for what reason you are having the glass replaced and whether any techniques are needed to meet your needs.
Choice 4: Extra option
Do you have single-glazing and is installing double glazing not an option because you live in a listed building, for example, or because you do not want to replace the window frame? Then setting windows are a good alternative. When installing a front window, a framed sheet of glass is placed against the interior window. This method has the same effect as thermopane glass and is easy to install.
