Aluminium Door FAQs
What’s the difference between Stepped and Contemporary styles?
Stepped echoes the look of traditional steel windows and doors, popular on period and character properties. Contemporary is a cleaner, more minimalist sash, suited to modern homes.
What is InvisiHinge?
A concealed hinge option that sits flush with the door, for a cleaner look with no visible hinge barrels.
Is an aluminium door secure?
Yes — Prestige Doors are PAS24-compliant with high-security multipoint locking, with an optional Secured by Design upgrade.
