Why choose an aluminium front door?

Key Features & Benefits

Here are just a few of the stand-out reasons why you should choose an aluminium front door for your home.

Thermal insulation – The material has built-in thermal properties which will improve heat insulation, keeping your home warm in winter and cool in summer.

Security – Although aluminium door frames can be more compact than their PVC or wood counterparts, the thickness of the metal makes them incredibly secure in the event of an attempted break-in. Robust, multi-point locking systems only enhance the level of security on offer.

Style – Elegant, attractive and oh-so modern, aluminium front doors are a great choice for those looking to refresh and update their home.

Durability – Aluminium is a strong and lightweight material that won’t rust.
