Secondary glazing is an economical alternative to double glazing where a “secondary” window is installed on the inside of an existing window, which remains in place.
Secondary glazing is unobtrusive, can be opening or fixed and can be installed quickly and without the need for re-decoration. It can be the ideal solution for listed buildings (subject to listing detail) or those in conservation areas where replacing existing windows is not a practical option.
Advantages of secondary glazing are:
- added security
- Suitable for listed buildings where double glazed units are not an option
- Eliminate draughts
- Reduced noise pollution
- Lower heating costs
