We bought this house for the fun open layout downstairs. It is a typical 3 bed semi where the living room and dining room windows were removed and big conservatory was added on. Both rooms have a huge opening of 2m wide. As you can imagine it takes a while to heat up the space and obviously doesn't meet building regs for carbon emissions (the people we bought the house off paid indemnity insurance for this). Tge conservatory is the only source of daylight to both living room and dining room. We would like to at least be able to close off the living room for when we are home and have it cosy when radiator is switched on. But we would like to have access to conservatory without the divide on lovely sunny days.
Is there anything you can recommend we do to keep more warmth in the living room without losing the light? Ideally we would like to have whatever is installed to not have a distraction on the floor. Would those single glazed internal bifolds work or would we not get any warmer? How about those thick heavy drapes/curtain things? Would they keep most of the heat in? The compromise would be loss of light when drawn but at least we would be warm? Any ideas?
