Greetings all...I am curious about the rise and rise of the use of bi-folds and similar devices to throw open a room to the elements. Virtually every illustrated Self/custom build appear to show bi-folds fully open. Could I ask why this is? Could members tell me how often they use them? Do you believe, in hindsight, are they such a grand idea or mere advertising puff? Surely, such huge glazed doors/windows are not very green and are net losses to a heating load.
I live in a converted, yet inefficient, Yorkshire cottage with a pair of trad French windows to the living room...facing a lush garden and receiving the sun until 2.30ish. The French windows have never been fully open in my 3 years here...I don't want a living room full of leaves. Just wondering!
