Are aluminium sliding doors right for your Trowbridge home?
These are the points a surveyor will go through with you when you choose aluminium sliding doors for a home in Trowbridge:
For a south- or west-facing garden in Trowbridge, solar-control glass in the sliding panels can keep a glazed room more comfortable on summer afternoons.
Whether you live in Trowbridge or elsewhere in Wiltshire, a lawn or patio sitting just below floor level can still take a low threshold, provided an outside drainage channel or a fall away from the door is planned.
- 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.
- 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.
- A polyamide thermal break inside every profile separates the cold outer metal from the warm inner face, cutting heat loss and reducing the risk of condensation forming on the frame.
Planning glass for the light in Trowbridge
In Trowbridge the shortest day has roughly 7 h 51 min of daylight and the longest about 16 h 36 min. The noon sun sits near 15° above the horizon in winter and 62° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.

How fitting works in Trowbridge
Once the opening is measured, nothing is ordered until you sign off the specification. Lead time is typically 4–6 weeks from survey sign-off. Our fitters protect floors, remove the old door, install and seal the new one and leave the area clean — usually 1 day for a two-panel straight swap; 1–2 days for larger doors for a door like this.
Rules for aluminium sliding doors 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.
Choosing the specification
- Threshold. A standard or low threshold, or a flush finish with a drainage channel outside where floor levels allow.
- Dual colour. A different colour inside and outside, so the exterior can match your windows while the interior suits the room.
- Glass. Double or triple glazed units in toughened or laminated safety glass, with solar-control or self-cleaning coatings.
Questions about aluminium sliding doors in Trowbridge
Can you match other doors and windows in my Trowbridge home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the 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 much do aluminium sliding doors cost?
Aluminium sliding doors start from a guide price of £3,295 for a 1.5 m two-panel door, fitted, inc VAT, at standard 2.1 m height. A 2.4 m door is a guide £4,295–£5,295, and a 4.8 m four-panel door is around £6,995. Glass, colour and threshold choices move the price within the range, and the final figure is fixed in a written quote after survey.
