Sun protection film effective?

[HA1966]

I see that this has been discussed earlier, but I can't find any definitive answers. Recently moved to a new home and have a LARGE window plus balcony door facing directly south in the bedroom. It's also one floor up, so scaffolding is required. Sweaty nights (and days) are therefore just around the corner 🥴

I'm thinking of booking a company to install solar film from the outside but hope to hear about others' experiences before I purchase anything. How much heat reduction have you chosen? Does it work well? Negative, positive?

See that this has been wondered about before but can't find any real answers. Recently moved and have a LARGE window plus a balcony door facing directly south in the bedroom. It is one floor up, so scaffolding is required. Sweaty nights (and days) are soon expected 🥴

I was thinking of hiring a company to install solar control film from the outside but hope to hear from others' experiences before buying anything. How much heat reduction have you chosen? Does it work well? Negative, positive?

Film protects against visibility and somewhat against glare. Does not protect well against heat. Awnings are the most effective against heat.

Hi,

We are facing the same question, so I wonder if you came to a decision on any solar protection film?
I've received quotes on several different models, with a specified heat reduction of between about 60% and 75%.
I am also curious if anyone with experience can testify if the effect is as good as the manufacturers state in their product sheets.

You know there's a difference between film and film, right? There are films meant for privacy protection and then there are solar control films from manufacturers like 3M, designed specifically to prevent heat intake.
I agree that awnings are probably the most effective option against heat, but for us, it's not an option since we don't want to make modifications to the facade for various reasons.

What kind of film is it? If no light comes in, neither does the heat...

As an emergency solution, I put up film in a bedroom that turned the whole window into a mirror for a few summers. It became about five degrees cooler in the room and a sunbeam on the neighbor's facade that almost peeled the paint.
But it was constant dusk in the room.

There is a plethora of variants on the market. There are cheaper options that you can buy and install yourself from the nearest hardware store, jula, biltema, etc. Often these have a metal mixture in them that absorbs heat, but this is what causes the mirror effect from the outside (as I've been told).
There are also options with different technology that don't have metal in them, so you avoid the mirror effect from the outside but get a transparent tint instead. These are of course more expensive. The more tint, the better the heat reduction, of course.

Which model have you installed?

Which model did you install?

Sentinel Plus 20OSW it seems. Dark and noticeably cooler.
But troublesome in the winter.

I would guess the lifespan is 5-7 years based on how faded it was when I took it down.

As I said, it was an emergency solution, then I put up shutters on that side of the house that we close when necessary instead.

Interesting! It seems to have over 80% heat reduction when I Google it, which sounds very good. Comparable to some awnings when I looked into it previously. The mirror effect seems to be high, something you also testified about.

The lifespan is also something to consider, which I forgot to ask the companies I've been in contact with. It's not entirely free after all, so you would like it to function for more than 5-7 years.

Jag funderar på samma, mest för man satt sig en dum situation då man tidigare valt färgat glas istället för klart, nu funderar vi på glaspartier men dom är alla klart glas de som vi kollat på. Så då har vi räcke med mörkare glas än resten.
