I would like to stick a coating onto my home office window to reflect infra-red radiation with minimal reduction of visible spectrum light. Does anyone know much about this?
Random internet searches mostly return results for mirror coatings, or broad-spectrum tints. Not quite what I'm after.
@anathema_device I've currently got wooden slat louvers in front of the window:
You can see they get quite warm where the AC isn't blowing directly onto them. From this perspective the louvers entirely block line of sight to outside.
I'm also getting a lot of heat through the walls and ceiling. A mate is giving me some leftover insulation for the ceiling. Not much I can do about the walls, though. Lord I hate plastering.
@tj We got blow-in insulation for our brick veneer walls - made an enormous difference! You can hang outdoor blinds on the outside of those walls from the eaves to cut down direct sun on them, and you can hang thermal lined curtains on the inside. There is no rule that curtains have to be only over windows.
Brickbats are cheap as chips and you can easily put those in the ceiling yourself.
@anathema_device@tj We have the same. I didn't realise they stopped it. We have a cracked window I won't be so quick to replace now I know that
We did it as a compromise when doubleglazing quotes came back too wild. I expect DG is still superior especially northfacing windows where direct sunlight hits the glass
@strykeroz@tj We have secondary glazing on our north facing windows, and the amount of heat that comes in, is incredible. Curtains and Venetians blinds make a huge difference though
@tj@anathema_device They still have a similar product but needs installation - wonder if there's something potentially toxic in the unapplied material? Or maybe just got tired of complaints about misapplied film. Or decided it was more profitable not selling it retail. https://www.3m.com.au/3M/en_AU/p/d/b00016645/
