Window-Coverage To Effectively Reduce Hot Summer Sun Warming South-Facing Room

[gl556tr]

I am having new windows with better insulation installed. They will be higher than the current ones, as whey will replace the draughty box containing the external roller-blinds.

Is there somebody who can recommend some sort of internal window-covering that can effectively/efficiently prevent undue warming of the south-facing living-room? Something that will let the light, but reflect warmth.

---> the two windows are about 1.5 metres wide and 2.3 metres high; the room having a ceiling over 3.10 metres in height.
Thank you.

You can get gas filled, sealed, double glazing units that do just that. I am sure also that there is glass with a low emissivity coating that can be used to make the units that does this also. It usually shows up as having a mirror effect though. Will have a look.

//Solar control glass is a hi-tech product developed by the glass industry to allow sunlight to pass through a window or façade while radiating and reflecting away a large degree of the sun’s heat. The indoor space stays bright and much cooler than would be the case if normal glass were used.
Solar control glass is not necessarily coloured or mirrored glass, although such finishes can be applied for aesthetic purposes if desired. It incorporates invisible layers of special materials on the glass which have the dual effect of allowing sunlight in, while repelling solar heat. Solar control glass units are typically doubleglazed, which means they also insulate well. //

Here you are GL. I was wrong about the mirror effect, but the Pilkington Glass link does explain it. Talk to your supplier about the costs involved in fitting these units in the South facing frames. If I remember correctly, again, they used to be pretty expensive. I never had much faith in the stick on solutions except for emergency safety reasons.

Here is some info on the solar reflective film that you originally asked for. This site is for a supplier but gives some useful tips. I will say again GL that I was never a fan of the film solutions.
P.S I worked for Solaglas for a while many years ago. There is more to glass than meets the eye. :))

T x3: Many thanks for your trouble and links.

I agree about film solutions.
Pilkington's energiKare is going in the right direction. Much as "induction", or any new product, it is expensive for a while. Then, after the rich have dished out on these novelties, with inherent teething problems, the improved version becomes cheaper over time - when we can grab them. C'est la vie.

Unfortunately, the windows have already been ordered. So, a solution would be something -- more modern than curtains? -- hanging inside them.

The main thing is to make sure there are no draughts in the house. Preparing your home for winter starts with checking the boiler and eliminating draughts to ensure warmth and comfort. We can restore sash windows at https://chameleon-decorators.co.uk/sash-windows-repair/ and this makes our lives much easier. We also remember to be aware of the weather and keep in touch with loved ones. I think your article will be helpful and interesting to many!!!
