French doors
A symmetric pair for the rear of the house: both leaves open in seconds and clear the whole width.
A symmetric pair or a single leaf in aluminium, opening to the garden in one movement, for period terraces, side passages and utility rooms.

A symmetric pair for the rear of the house: both leaves open in seconds and clear the whole width.
One leaf where a pair will not fit, with the same security options as the rest of the house.
Open-in keeps leaves off the terrace; open-out frees the floor inside, and wind presses it onto its gasket.
Every option is confirmed at survey, against your opening and your build stage.
