Secondary glazing in period house

[Sophforthe100]

Anyone installed this?
Does it look OK?
Did you dot he installation yourself and was it easy enough?
Main objective is to conserve heat.
Most of our windows are double glazed, but we have one which is not and the difference in thermal efficiency is really noticeable.

We have large square bay windows that are very energy inefficient. Would I be able to attach the panels on the outside of the bay?

My parents had secondary glazing done a few yrs ago, grade 2 listed so had to get a company in to do it. Original sash windows are still fully working & they are able to open the secondary glazing so plenty fresh air. It looks fine actually & made a huge difference to heat loss in house, they have several bay windows which have been done.

I live in a period property. I have got my done recently from granada secondary glazing. Very happy with the work.

I thought I'd update my thread in case anyone else is interested.

We finally ordered the magnetic perspex secondary glazing and installed it this afternoon and it looks great - as in you would not notice it was there!

Time will tell how effective it is at reducing heat loss, but it was really simple to install and despite having wonky, old windows and the white finish not quite matching our pale blue frames it is really unobtrusive.

DH was initially quite sceptical but he is now pleasantly surprised.

Glad to read your update, @Sophforthe100 I'm sure you'll feel the difference when the colder weather sets in (which will be next week the way we are going!!)

Which company did you go with in the end, out of curiosity?

We went for Magneglaze - as recommended by you. As it was only one window and they seemed the simplest, albeit a bit more expensive, and the video on the website made it seem very easy.

They were very quick too.

@Sophforthe100 been looking at this too. What thickness plastic sheets did you use? Thanks

@SallyLockheart We had 3mm, as supplied by these guys: https://www.magneglaze.co.uk/

Do keep us posted. Am still agonising about secondary vs this vs getting rid of a single thin glass but beautiful deteriorating Georgian window. It's definitely losing me too much heat.

Would anyone be happy to post photos of their secondary glazing? We have some old glass secondary glazing in our Edwardian house which is quite shabby and obtrusive to look at, gets condensation, plus I can’t clean dead flies out from between the gaps!

However it looks to be from a well known brand so is probably quite effective.

Ideally I’d love to replace with something prettier to look at, so v interested in the thermal / sound qualities of the Perspex option or getting new glass secondary glazing, just don’t want to waste money!

Here's ours @LuckyEarthDragon During the daytime you cannot see it at all, at night there is a reflection, but as we usually keep the curtains closed it's not really an issue.
We have get the magnetic perspex type.
The room is noticeably warmer since we installed it.

Gosh that looks excellent, thanks so much for posting as we actually have quite similar windows with the monkey tail handles, so really useful to see how neat it looks! :)

Yes, we are really pleased with it. Very easy to install too.

We have some very small, curved, bay windows, with even smaller glazed panes, one of which opens, and will have to be able to open with secondary glazing in place. Anyone know of a place that can do panels for really awkward little windows?

@CutesyUserName

Can you tell me which magnetic tape you ordered for your panels? I'm looking at using the same company as you for the plastic panels, and can't see that they supply the tape. Products on Amazon have awful reviews!

(Have looked at the Magneglaze website but the constant "falling snow" effect they have on the screen is extremely irritating when trying to read the details!)

A company called Geckoglaze make perspex panels with a squishy taped edge that go onto the glass (rather than the frame), so the window still opens as usual. They've a slightly worse u-value than Magneglaze and about 30% more expensive. But we've used on our bathroom windows and they seem pretty good.

Because its perspex, it might flex enough to go round a slightly curved window, but you could just contact them to see?
