Secondary glazing

Something we do not need to do to ‘Live Lagom’, in our house, is double glazing – we already have it. When we bought our home, very rickety, original, 1970s single glazed, wooden windows were in place, covered in condensation – they had to go.

We were a whisper away from replacing them with UPVC – it seemed so convenient…

Norwegian wooden windows

Something deep inside stopped us though, we were lucky enough to have gone on enough shoots to have heard about the beauty of Norwegian windows… modern, soft wood, double glazed windows… perfect for our brutalist, but we feel, very loveable, clunky 1970’s villa.

They can be supplied in any colour –

French Grey

We chose ‘French grey’ by Farrow & Ball… We have never regretted it, the cost was the same as the UPVC option.

What do you do if you live in a period home though?

UPVC is not an option, particularly if you are in a conservation area and neither is modernist Norwegian softwood!!

The answer is Secondary glazing, available from The Plastic People. A truly marvellous product, made of polycarbonate glazing panels that are installed on the inside of your existing window.

They work to provide an additional barrier that prevents heat loss and reduces exterior noise. Cheap, easy to install and if you currently have condensation on your windows, secondary glazing can help, as it prevents draughts from entering the room. This limits the availability of a cold surface, which in turn stops the water droplets from forming.

However, in some circumstances, you may get condensation forming on the secondary glazing itself. There are two ways this can happen.

1) Condensation forms on the secondary glazing. This happens when your windows are ineffective. Essentially, the secondary glazing becomes your windows, as the window itself does not prevent draughts effectively. Condensation forms as the secondary glazing becomes the cool surface. To combat this, you’ll need to repair the window.

2) Condensation forms on the window itself. This happens when there is too much air in between the window and your secondary glazing system. If this is the case, you should improve ventilation. This can be done easily by drilling a small hole in the outer window frame — pack it with cotton wool to prevent insects entering.

The benefits of secondary glazing far outweigh any complications that might crop up, all the problems mentioned above are easily solved and your home will be quieter, warmer and cosier.
