Why secondary glazing is not always the best solution

Research into secondary glazing is often prompted by the first winter spent in a Grade II listed house. It’s a well-known fact that old single-glazed properties can come with a compromise on comfort. Draughts, noise and an environment that may not be as warm as you would like are often the hallmarks of living in a 19th or 20th-century house that has single glazing and old cottage timber frame windows.

The challenge with listed properties is that any structural alteration is subject to restrictions so you cannot just change the old windows for modern sealed units. The local Conservation officer has to give permission for any change to the windows and the householder will be limited on the types of glazing and frames they can choose. However, a quick internet search will reveal the option of secondary glazing as a realistic alternative and it’s cheaper too.

Secondary glazing can seem like the answer – it’s cheaper than a full window replacement and can solve the problem of obtaining listed planning consent for new windows or double glazing. It’s also pretty quick to fit. However, secondary glazing can present the homeowner with some issues and may not turn out not to be such a perfect solution, here’s why:-

Fineo glazing can properly reduce the level of condensation and will not affect the character and charm of your period windows. It is slightly more expensive at the point of installation than secondary glazing but doesn’t have any of the problems or drawback associated with the latter.

Retrofitting ultra-thin, high efficient vacuum double glazing starts from £900 for a single Victorian or Georgian sash window but will offer the householder thermal performance, superb energy efficiency and a warmer environment. Best of all, the style and character of the original windows are preserved so the householder can enjoy modern, 21st-century comfort in their period home. This is definitely money well spent.
