Default Window film to cut down on heat

We've got a small office, with one wall that faces almost exactly south-
east and is damn near entirely glass. With no aircon and a big chunk of
computer kit in the office, you can imagine what it's like at the moment!

What's the options for some kind of film for the windows to cut down on
heat transmission, whilst retaining most of the light transmission? The
building management don't want anything to be "visible" from outside - no
logos, no visible tint, etc etc.

Suggestions, please...

Mirror reflective metal venetian blinds?
Venetian blinds can then be wound back up when not needed, only needed
a few weeks a year.

Then you need to sort out a few extractors - window mount Ventaxia or
Xpelair 12", get a good cross-flow of air moving which will greatly
reduce perceived temperature re discomfort.

Visible Light & Infra Red are rather related :-)

The heat is inside by then and this thing called the greenhouse effect comes
into play.

There isn't anything that will be effective and won't be visible in some
form or another. The least obvious would be a neutral tint solar control
film. Even a light tint, which you might persuade them to accept, will
reduce solar gain by a noticeable amount. Google for solar control film or
heat reflecting film. The other way is an external sun shade, like a
traditional extending shop canopy.

True, but without altering the visuals of the building there is little
alternative.

External blinds avoid superheated air in the interior.
3M might do a film which will reduce transmission of IR.

"js.b1" gurgled happily, sounding much like they were
saying:

Not an option. There's vertical blinds at the mo - and we've already
tried to get those replaced for purely functional reasons...

Then you need to sort out a few extractors - window mount Ventaxia or
Xpelair 12", get a good cross-flow of air moving which will greatly
reduce perceived temperature re discomfort.


Unfortunately, definitely no chance of it being an option...

About what I thought.

The least obvious would be a neutral tint solar control film. Even a
light tint, which you might persuade them to accept, will reduce solar
gain by a noticeable amount.


Mmm. Mebbe get some samples, and see what's visible and what's not.

Google for solar control film or heat reflecting film.


Yeh, tried that. Four squillion fitters, all with very little in the way
of useful info.

The other way is an external sun shade, like a traditional extending
shop canopy.


I dread to think of the office manager's reaction.

If you just stick a patch on it'll be visible even if 99.9%
transparent in visible light. However if you stick something neutral
to every bit of glass in every window, it will be "invisible"(*) as
all the window glass will look the same.

(*) Provided you don't go silly and stick a mirror film on. B-)

Thanks for that, they seem to have a better range and variety of sizes
on offer and are a lot cheaper than windowfilm.

Oh, sure - but it'll give an indication of HOW visible it's going to be,
compared to all the other windows of all the other rooms...

You could, of course, do away with all the computer stuff - or
relocate.
