Send your questions to propertydoctors@telegraph.co.uk Q Our conservatory has a sloping roof of six glass panels, each of which is fitted with a concertina type blind. They are always kept down as we find the temperature inside is too hot when the sun is shining. Fixed blinds would be the replacement option, but as a cheaper alternative I am wondering if there is a suitable paint that could be applied that would reduce both the glare and heat transmission.
