I've got to be honest. I will be flabbergasted if anyone with a conservatory has been able to use it since the middle of May. This unprecedentedly roasty toasty summer has meant our homes have been getting hotter and hotter as they hold on to the residual heat from the days before.
But for those with glazed roof additions? Oof, they will have been utterly sweltering this year. And trust me, I know from experience. For the first 10 years I lived in my three bed house, I had a conservatory with a glass roof which, by lunchtime on a sunny summer day, was considerably warmer than it was outside. And in a heatwave it became disgustingly hot and an utterly unusable space.
