Aluminium will never rot or rust and there is no need to repaint every few years. Just give the frame a quick wipe every so often using the cleaning products in your Renka care and maintenance kit and your windows and doors will look as good as new for years to come.
The nature of the pivot door is such that the frame cannot overlap with the top and bottom of the door leaf. Whilst a brush strip will help keep out draughts, this door is not designed to keep out driving rain and strong winds. Think of it as a great option to install between the main house and a conservatory or garden room rather than as an external door.
