Secondary double glazing for 'different' windows.

At this time of year our house can get very cold. We have really tall single glazed North facing windows. We are loath to change them to double glazed units as they are the original victorian wood (and possibly some glass) but, as the house is open plan (ish) we would like to add secondary double glazing.

I have heard that it is possible to have permanent secondary glazing which still allows normal opening and closing. Has anyone had this fitted or did I dream it?

DD has had all thei naff double glazed windows on their Victorian terrace replaced with wooden sash windows which were made to match any existing original windows in their street. Hand made but also very effectively double glazed. Not cheap 😱 but for a single window well worth it in your case I should think.
Try some quotes. They went to a local firm on personal recommendation rather than a big national one .

Oops, misread your post, not just one window. With new wooden double glazing you would not need secondary . Secondary is an unsightly option, I think, we had it in our 18th C stone cottage but as the windows were small you didn't notice too much.

My parents had secondary glazing installed years ago but mainly for noise reasons - lived near Heathrow. They had it done at the edge of the windowsill for this reason but it was very effective. They could slide open the windows to open the outside ones - worked fine. I have since seen them very near the frames of the existing Windows. I would get a couple of companies in to give quotes and see how their products work.

I have the same problem. Tall single-glazed sash and case Victorian windows.
3 ( in a bay) face east and 3 (individual) face south.
I had Ventrola to renovate them and they were overhauled and draught-proofed, which made a big difference. I was told at the time that double-glazed units would make them too heavy to open.
My main problem now is that, because the draught-proofing is so efficient, I'm far more likely to have condensation first thing on winter mornings.
Like mb 's dd I couldn't consider new upvc type units so I'll stick with this.
I did wonder about a secondary installation but any I have seen are so unsightly. I'd be interested if you find something suitable.

We are keen to keep the existing windows but I think I have heard of something that is fitted very close to the original glass rather than the old ugly sort......I think!

I have seen some secondary glazing which attaches to the fixed part of the window frames and is slim so very neat and hardly shows at all.

That might be it, ww, can you remember who made/fitted it?

No - have only seen them but have no experience - my dad had them done in the 60s. I would try national companies and local ones if you can. When we had normal replacement windows we had some made locally for some windows but when we had the rest of the house done chose a national company as their product was far superior.

We have Everest secondary glazing in one of the bedrooms in our bungalow. They slide open so you can access the main window and lift down for cleaning.

Friends of ours have the same ones in the lounge of their listed farmhouse as they're not allowed to alter the original windows.

There are a range of secondary double glazing suppliers who specialise in fitting windows in older houses and Listed buildings.

Looking through my current copy of the magazine 'Listed Heritage' these are some of the companies listed as offering this service: CN Glass,; CosyHome Company,; Selectaglass,; Storm Windows,

I list these because I have seen their products at an exhibition because we were considering them ourselves.

Secondary double glazing is amazingly effective for sound-proofing.
