Heat reflecting window film

[phatboy]

Hi experts,

I need to do something about the heat in one of our bedrooms that faces south. I think the best way forward is going to be some heat reflective film.

I've seen some good ones that don't reduce light levels much, but do have very good heat and UV reduction. For example 3M Prestige Clear.

However, being in Jersey, there is nowhere that stocks it. 1 place has provided a quote and it would cost more than the window did!

Can any experts advise on any other good films, and where I might buy them? 3M seem to only be available through authorised installers.

Thanks in advance for any help....
Tim

Im currently fitting a shed load of solar control 20 across roughly 2000 BT exchanges to keep the heat down along with upgraded air con, should keep me busy for the next few years

We buy our film from Arc Films up in Wigan but theres others, stock films is another, both would be happy to ship to you, also try ebay and buy by the metre. Quality wise look for a film that has real aluminium reflective foil NOT the cheaper end of the market dyed stuff, will last half as long, quality films are guaranteed for 10 years now

Bought some on eBay to fit in my loft room.

Thanks all,

I've found a company on eBay who seem to know their stuff, and their film is £20 per metre.

I've also found someone who can sell me 3M film, and it's about £40 per metre - Prestige 90 External. I think it's metal free though.

Any thoughts on whether it's worth the premium of 3M over a decent no-brand film?

Also is the external film better? I've read various things, one that exterior film prevents the heat even getting to the glass and so reduces the risk of cracking, but I have no idea if this is valid of not.

Thanks
Tim

Correct external film is better as it stops the heat before it gets to the glass, filming the inside can trap the heat between the film and any heat reflective glass like low e, however sometimes its not practicle to film outside so it has to be internal, also you are meant to seal the edges on external film to stop water ingress, clear varnish and a little touch up brush

Thanks, very re-assuring.

Fancy a trip to Jersey to do some installation?

In the end, I got some Solarguard Solyx Ultra Cool Ir8360 film, and an experienced friend cut it all at his work, and we applied it 10 days ago to the outside of all south and west facing windows.

Results are very good - minimal change to window appearance from inside, a bit more reflective outside. But most importantly, on a hot sunny day, the room is at least 3 degrees Celsius cooler!!

Yeah 2 - 3 degrees is about right, its certainly in the region of what i'm seeing on my jobs
