Double hung windows: Letting in the breeze without letting anything out
Living on the Gold Coast, that breeze is sometimes at a premium. Double hung windows allow both the top and the bottom sashes to be open. The flexibility is particularly great for homes that combine low windowsills with children or pets. Opening the top sash of a double hung window lets the breeze in while closing the bottom sash stops the kids and the pets falling out.
You can have them sashless too: with Aneeta windows there’s no wood or aluminium across the horizontal part of the window.
