Rule 1 when building in inland Spain is to heavily insulate the roof - to keep the sun out. Keeping Heat in is secondary. Summers and winters are more extreme than UK, just for reference.
Therefore if you have plenty of insulation but your house is still over heating in summer, you may well be using your Windows and Doors wrong! Keep them closed and shaded in the day, and open at night to let cool air in. Expats here make Big mistakes designing glam glass walled houses, a fast track to over heating or insanely expensive glazing
And think about venturi effects draughts, dragging cool air in at the bottom and drawing It through the House and out the top. Solar powered fans are simple. Ceiling fans are low power and surprisingly effective.
Sleep downstairs in summer. Plant trees to shade your house. Rethink patios that Heat Up rather than cool down the Air around your house.
It's not expensive to insulate everything, roofs, floors, especially.. And winter energy bills everywhere are high in homes where people insist on lounging around in their undies.
If insulation not work both ways, the question for me was if we have taken aerosols out, Now talking of putting protective geo engineerng back in.... Meanwhile wáter vapour is a great insulator compared to CO2.
