Reflective coatings on the glass

all glass is K-Glass

K glass helps reduce heating requirements but makes the situation of unwanted
solar gain far worse than plain glass. Too late now but you might have been
better off with Pilkington Suncool rather than K for large or south facing
windows .

Be interesting to see what happens to the temperatures around the house and in
the loft space with zero contribution from occupancy. Then with the outside
temperature profile and sunshine figure you'll have a better idea of how much
you need to reduce the heat gain and from where.
