Read on, as we outline their respective security features.

Aluminium French doors

Fortunately, the lock cylinders found on today’s aluminium French doors are built to strict, modern UK standards, meaning they are extremely sturdy and ultra-reinforced.
  • The glass that is used on aluminium French doors has undergone thermal treatment in order to toughen it up substantially. Generally, the strength of thermally toughened glass is up to four or five times that of annealed glass of the same thickness. Also, the external removal of any glass is prevented via the use of internal glazing beads.
