Our kitchen is so hot in the summer (wonderful in the winter!) Big glass sliding doors and huge roof skylights that unfortunately do not open. (We did not do this ourselves.) Think straightforward side return in terraced house.
We have gotten eyepopping quotes for motorised solutions like awnings over the skylights and the back window -- many thousands of pounds. Can't afford this.
Last summer we got some outdoor curtains and that worked pretty well with the big glass door. The bigger question is the skylights. They are surrounded by roof membrane so you can only mount on the glass itself so external blinds may be difficult. Someone gave me the idea to put hooks in the brick wall around it and put up some sunshades (very easy to access this part of the roof and that bit is flat.)
Have thought of film but had mixed reviews.
Any other ideas you would be looking into?
Thanks!
