Are aluminium sliding doors right for homes in Northamptonshire?
A few practical points decide whether aluminium sliding doors suit a particular room and opening:
For a south- or west-facing garden in Northamptonshire, solar-control glass in the sliding panels can keep a glazed room more comfortable on summer afternoons.
Thinking about a dark frame for a house in Northamptonshire? Anthracite grey and black powder coats show off slim aluminium sightlines, and dual colour keeps the inside lighter if you prefer.
- Narrow aluminium frames and meeting stiles put more of the opening into glass, so you see more garden and less frame than with a uPVC door of the same size.
- Aluminium is stiff enough to carry wide panels without bowing, which keeps the number of vertical frames low even across openings of four, five or six metres.
- Multi-point hook locks grip the frame at several points along the closing edge, while anti-lift blocks stop a shut panel being raised off its track from outside.

Daylight and glass in Northamptonshire
Sun angles matter for big glazed doors. Around Northamptonshire, midday sun reaches about 61° in summer and drops to about 14° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

Approvals in England
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
Questions about aluminium sliding doors in Northamptonshire
Is the price different in Northamptonshire?
No. Guide prices for aluminium sliding doors are the same across mainland Britain, including Northamptonshire. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
Do aluminium sliding doors need Building Regulations approval?
In England, replacement sliding doors are controlled fittings, so the work is either carried out by an installer registered with a competent person scheme, who self-certifies and notifies, or notified to Building Control. The glass must be safety glazing to BS EN 12600. Forming or widening an opening is structural work needing its own application and calculations. Wales, Scotland and Northern Ireland have their own rules.
Are aluminium sliding doors secure?
Aluminium sliding doors can be very secure when they combine multi-point hook locks, anti-lift blocks and laminated glass. Systems are available tested to PAS 24, the UK enhanced security standard for doorsets, and an enhanced security locking pack can be added to your quote. Most systems are glazed from the inside, so the glass cannot be unclipped from outside.
How wide can an aluminium sliding door be?
An aluminium sliding door in our range can span from about 1.5 m to 6 m, split into two to four panels. Each panel is usually up to about 2.5–3 m wide depending on the system and the weight of the glass. Wider openings take more panels, and beyond about 6 m a multi-track or lift and slide system is usually the more practical choice.
