Windows UV Film to Keep the Heat Out

Our living room has a lot of glass to enjoy the view, but in the summer it transforms into a furnace. The big [flat] areas have been equipped with outside blinds which I lower in the morning courtesy of the owners.

However, there is a big round corner which is closed with 12 narrow and tall windows (to accommodate the round shape) - imagine half a cake, 2,5m tall with domino tiles shaped windows... The owner/regie has refused to fund the (nearly) 20k quote for outside blinds, narrowing the options to UV film to block the heat.

Last week I setup a visit with one of the companies in Geneva offering this as a service and lo and behold, quote was CHF250/sq.m. arriving at almost 5k for the whole lot.

This is a bit more than I'd like to spend, so questions to you are:

1) Do you know anywhere I may find quality UV film to install myself at better prices?

2) Have you had a similar issue and a better/alternative solution you can recommend?

Thank you for all ideas and feedback

Re: Windows UV Film to Keep the Heat Out

My company in London used to supply and fit this, I think we used to charge between 70-100 per sq m (dep on the size if the job) 10 years ago so 250 chufs is not that expensive (for Switzerland).

Do not try to fit it yourself, the film is like brittle cling film and even with 2 professional fitters is very difficult to not get creases or bubbles (you apply it by soaking the film and glass with soapy water which you then squeegee out). It's a messy job.

You could try to source the film in the UK and see if you can get a general signage contractor to fit it or ask a sign company for a quote, many offer this service (at least they do in the UK) and should be a bit cheaper.

Re: Windows UV Film to Keep the Heat Out

Thanks, Mike! So the film is not overpriced, which is a good start

I think I'll have to look into alternative solutions - although it may be tricky: top floor means a lot of wind even on quiet days, so installing just anything on the outside won't do... Fearing that on a bad stormy day pretty much anything not attached with anker bolts will be torn off.

Re: Windows UV Film to Keep the Heat Out

Forgot to mention, the film is fitted on the inside of the glass!

Re: Windows UV Film to Keep the Heat Out

Can you paint the window glass outside with some white wall paint?

Best paint on the inside with emulsion. Or you could hang just net curtains up.

Re: Windows UV Film to Keep the Heat Out

I thought of curtains but then - heat still comes through the windows and *inside* the room... I was hoping there is a smarter way to block the heat while it is still on the outside...

Re: Windows UV Film to Keep the Heat Out

Would there be a possibility to install outside awning(s)?

I am thinking about the "wind sail" style. My guess is you will need two or three to cover the area.

You might get some ideas from this website.

http://www.primrose.co.uk/shade-sails-c-85.html

The idea is that you remove the awnings in the fall/winter when you want the sun coming into the apt. Once the film is up, you can't take it off.

True, but the film is see-through, as in you keep the view but kill the heat. The sails are cool but with zero space outside the windows, I either have to block the view completely or not install them - no middle ground where depending on sun intensity/activity one may put up/down or, have it on all the time without obstructing the view.

As I was writing above, I gather there will be tradeoffs, no way to have it both ways: keep the view AND kill the heat. As in, without spending 5k on UV film

Cheers

Re: Windows UV Film to Keep the Heat Out

we had film installed at one of our work offices a few years ago, we chose from 3 tint levels, we took the darkest as the UV figure was the same.

the film was fitted on the outside.

they shouldnt have bothered it didnt make any difference.

Re: Windows UV Film to Keep the Heat Out

In case someone comes back to this thread, I saw a supplier/installer at the Habitat + Jardin in Lausanne this weekend. They produce the films and install them in all of CH.

The problem with some of these small CH companies is that the website is only in FR.

Here is the link to the film that reflects the heat. They also have privacy and car films.

Re: Windows UV Film to Keep the Heat Out

I installed this stuff from Hornbach on a full wall of patio doors:

http://www.hornbach.ch/shop/d-c-fix-...2/artikel.html

- there's a noticeable reduction in heat intensity inside from the sun, and less glare

- the inside window gets hot - so overall it probably isn't keeping that much heat out of the room; that's kind of OK, at least it's up at the ceiling and not heating up all the furniture

- it says it can't be mounted outside, but if I was doing it again I'd probably give that a try on one door to see what happens

Unfortunately not in stock anymore.
