Large open plan TV room and dining room with large glass lantern roof with solar

During the heatwave of 2018, we were contacted by a lovely couple from Beaconsfield in Buckinghamshire, wanting a horizontal lantern roof blind for their family room. Practical problems included glare when watching the television and heat loss during the colder evenings. Their family room was a single storey extension from an already stunning house, leading directly off from the kitchen into a large open plan TV room and dining room with a very large glass lantern roof with solar glazing, as well as folding doors onto the garden.
