The integration of screens, shades and hardware ensures that these folding doors can be used flexibly, at different times of the day. While the screens keep insects at bay, the shades filter light and provide privacy. The screens and shades are built-in, and retract completely into the doorframe, while the hinges and locks are concealed, so there is nothing to hinder the view. This practical system is available with a wood or aluminium interior and a thermally insulated aluminium exterior.
