That reduced the temp in our house by about 2 degrees on really hot days. It also reduces UV damage to furniture / flooring etc.
Having said that, we now have 7 AC units and two heat pumps installed to manage temps in our house. Super insulated / air tight new builds are impossible to heat manage properly. It was 29 degrees in my office this morning, before 8am.
Now sitting in a lovely 20 degrees, using around 0.2 kWh
Worth noting that heat pumps, AC cassettes and installation are currently all VAT free...

Have ordered some of this. The specs look great, 38% reduction in the increase of heat due to sun, total rejection of UV, 70% of visible light still gets through (even for a single pane of glass that is only 86%, so this is "visible but minor reduction in light" which is great as it will prevent glare).

I have this for my garden office, which was getting warm even when it was frosty outside.
I'm also going to have an exterior canvas awning to stop the sun getting to the bifold in the first place.

That stuff could be good. We both work in our lounge which is sun facing in the afternoon so heats up a lot. It's 25C in here now.

Oh yeah, all blinds closed but the sash windows open behind them... and then fans on.
The day starts well, ambient temp right now is only 22'c indoors - but that's roughly what it is outside too (measures 23'c currently)... so really the problem is that I can't keep the indoor different from the outside temp on hot days. I can create a bit of comfort from the shade and moving air... but when it gets to 28'c outside it's probably 26'c inside... 32'c outside and probably 29-30'c inside.
This is the problem with lots of windows and skylights... way too much external heat comes in to this space.
My little office gets warm really quickly too - which is great in the Winter, not so much in the Summer.
