I have a whole wall that I need to block off with some sort of door. I'm thinking that a bi-fold door would be awesome. However, my husband kind of wants a sliding door. I just think how cool it'd be to have a whole wall made up of a door that could easily be tucked away when needed. This would make outdoor barbecues a lot easier. It would sure save me from having to open the door every time. http://www.superiorwindows.com.au/content/Products/BifoldDoors.aspx 

I couldn't tick one or the other of the boxes – I think the choice has to be made contingent on so many variables. In fact we have painted timber, double-glazed bifolds (with a fabulous retractable pleated fly-screen) at the end of the dining room leading out onto a terrace and a painted timber, double-glazed slider (with a timber-framed sliding fly-screen) on the other side of the kitchen (but on the same axis) opening onto a raised timber deck. Each works really well in terms of function and aesthetics but they would not be interchangeable as the different locations determined which was more suitable – but they have been made by the same highly skilled window craftsman and have given us nothing but pleasure. And on a hot, steamy evening with both open we have the most wonderful cross ventilation.

Where did you get it, by the way? I am actually looking for some doors for my terrace. The thing is, I don't want them to be opaque. I would like the same design for the lines to be a little more subtle with more transparent glass. Actually, I think there is no need for ornaments on the glass. Just a little shading would be more than enough. I am also curious about the prices on this one because if it's triple compared to a simple door, then I am not even considering

swinging doors need a much bigger space to open and block access to side walls unless they open outwards (also harder to waterproof) and you remove the car...we have a rear 2.4m wide roller door without any intention of driving through to the rear garden (although occasional rear car access doesn't cause too much harm to the grass) but the wider opening is so much better for more light and easy access with a wheelbarrow or lawnmower and we have a 1.2m narrow concrete path across the outside rear of the garage to extend the total floor area which is ideal for working with table saw etc i suggest you cost the roller door with or without controller as the twin hinged door with suitable handles and locks may not be any cheaper and far less convenient
