Excellent tutorial. Very elegantly done with best graphics. About ventilation I have experienced in my old home even though beam filling is not done, hot air gets trapped and temperature measured is about 70 C when ambient is 30 to 35 And this causes the room bellow also very hot, inspire of false ceilings or mezzanine floor. How to ventilate such roof?
Thank you for your comments. You may try to provide a dormer window within the roof for ventilation. If however you have a false ceiling it may be a good idea to provide ventilators above the ceiling level in the walls above the false ceiling and in addition provide glass wool insulation above the false ceiling.
