I have a sheet of acrylic/perspex stuff that is attached to the window with velcro, which has a hole and a fitting for the extractor pipe, so the window is sealed and the air can escape.
Portable units are flawed by the fact that they extract air, so always draw in air from somewhere else. But they still do a good enough job. My bedroom yesterday was 28c when I got home. 9000BTU portable A/C kept it at 20c all night, plus the lower humidity makes it so much more comfortable.
Lovely hot day and some **** decides to have a bonfire.
I'm lucky I suppose, I can go to sleep easily regardless of how hot* or cold it is, and get a good nights sleep.
Makes all this talk of needing AC to help sleep slightly baffling to me, but I guess we're all different.
*Only exception to that was when on holiday in Kalymnos in the late eighties when Greece had a heateave on. A British woman died from it the week after we left the island.
It got to around 114F in the sun duriing the day and in the nineties at night.
I can still remember waking up in the middle of the night, straight onto autopilot to the fridge to down a pint of water.
Whilst everything around them is nice and dry no doubt...
https://www.gov.uk/garden-bonfires-rulesYep, what a fool, he has been having bonfires on a frequent basis during the weekday afternoons of late, sadly there is no rules for this sort of thing.

Bought out ALL the Ice Cream from the local store. Prepared to just wait out tomorrow with the stash I just obtained. I just hope it's enough to last tomorrow...![]()
