My partner has recently purchased a top floor flat with a converted loft (converted as an 'un-inhabitable' space, i.e, no fire escape, loft ladder access only). It has 2 velux windows and no other means of ventilation. It gets very hot up there when the windows are closed, so much so that the glue on one of my posessions has started to melt. The loft is fully insulated.
Any ideas on how I can cool it down, my current ideas are...
Install some kind of air brick/s - don't know if that would work.
Fit velux blackout blinds - don't know if that would work either.
Air conditioning - not good for environment/expensive.
Any advice would be very much appreciated
