Secondary glazing for sash windows

edsredshed

Does anyone have any experience of secondary glazing on sash windows. Does it work and how does it look? Also, I'd guess you can get pretty heavy moisture build up (warm air vs cold air) is this a problem?

With winter coming the I'm beginning to be reminded how drafty my sash windows are and can't afford a replacing with double glazed. Is secondary glazing a good enogh option.

Thanks

also dont forget the weight may increase and could effect the balances.

Secondary glazing can't effect the weights or balances, it's set back on the window cill.
I use to be a rep for Everest, about 30yrs ago and i got secondaries for my windows, they were great. When i did eventually have to renew the frames i kept some of the secondary glazing on the main windows so as to have triple glazing.

Thanks but bit confused...:o Does the secondary glazing sit on the wooden frame of the window (if so outside frame or on the sliding sections?) or does it attach to the surrounding wall?

I have seen secondary glazing set into the window frame of old sash windows. In fact, I use to live in a house with it!

No that's not secondary glazing, that's putting a new double glazed unit (the actual glass) into your old frames .

What they do with secondary glazing, they'll measure inside the house the distance between your cill and where the lintel is at the top of your window, then measure across between the two little walls of the window recess.
Then they make a wooden frame to fit snug in that gap, maybe 2"x2" timber, now another alum/upvc fram is attached to the wood with runners for the new single panes of glass. Normally they would be fitted as close to the original windows as possible, but sometimes such as when noise is a problem they may set the new windows back to the edge of the cill, so you have a 4"/5" gap perhaps.
The only fault with secondaries is you have more pieces of glass to clean, every so often you'll need to lift out the glass from the runners to clean the windows.

I was looking to see could i see a picture of how it works, this may help and it's got some prices on it for Diy stuff, i just googled secondary double glazing, lots of firms are there.
Secondary Glazing UK supplied by DIY Plastics UK to trade an DIY

Obviously the Diy stuff isn't going to be as neat as a professional job but if cost is a problem maybe you could try one of two windows, perhaps the likes of B&q may have them on show.
If you found you were getting condensation get a few of those little gel things, or even a egg cup with something like bicarb or something and leave it in the gap.

Secondary glazing waste of time. For draughts, there is a simple and easy (and invisible) fix- search my previous posts for cling film. (No, it's not stretched across the window).

If you think it's a waste of time you've obviously done it wrong, as i said previously i spent two years as a rep for Everest, i hated the job 'cos i'm not pushy enough to be a salesman but most of the reps including me bought secondaries for our own houses, we all knew it was a good deal.
