Bit of a strange one- we had an extension done recently and have a roof light now in part of our extension. Whilst it’s lovely to look out of, brightens the room etc in this heat it makes the room punishingly hot.
Our friends on the south coast used a local company to install a UV film which kept the light coming in but heat out. However, would like to use a local firm if possible.
We’ve thought about a recessed blind but unless you go electric are clunky and gather dust.
