Durability , Security & Strength

Unlike other door materials, Aluminium neither absorbs water, rots or rusts. This means that if you are looking for new or replacement Aluminium external doors, their frames and panels are completely rigid to prevent warping, twisting and sticking. All Harefield’s Property Improvement  external Aluminium doors are fitted with high security locking systems as standard. All Harefield’s Property Improvement Aluminium doors have insulated solid panels, faced with strong, durable aluminium sheets which resist flames and physical attack adding security to style. In addition, the glazed sealed units in all aluminium glass doors have a toughened outer pane which adds further safety and security. Aluminium doors have slim line profiles which allow you to choose half or fully glazed doors for maximum light without compromising strength or security.

With a wide range of designs, Aluminium external doors can transform the look of your home, whilst providing a very high level of security.
