Are aluminium sliding doors right for homes in County Durham?
A few practical points decide whether aluminium sliding doors suit a particular room and opening:
Before aluminium sliding doors are ordered for a County Durham home, the survey should check the opening width, floor levels and existing lintel, so the quote reflects the real job.
If your County Durham home has a rear extension or kitchen-diner, aluminium sliding doors let you place a table close to the glass, because no panel swings into the room.
- Polyester powder coating is baked onto the aluminium in the factory, giving a hard, even colour that resists fading and chalking and does not need repainting in normal use.
- Panels run on adjustable tandem rollers along a hard-wearing track, so even a heavy double or triple glazed panel can be opened smoothly with one hand.
- 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.

Approvals in England
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Questions about aluminium sliding doors in County Durham
Can you match other doors and windows in my County Durham 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.
Are aluminium sliding doors warm enough for a UK home?
Thermally broken aluminium sliding doors are warm enough for most homes, with typical whole-door U-values around 1.2–1.6 W/m²K double glazed and 0.8–1.1 W/m²K triple glazed, depending on the system. In England, a new or replacement door in an existing home with more than 60% glazing must reach 1.4 W/m²K or better, so the glass is specified to meet that. Wales, Scotland and Northern Ireland have their own rules.
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.
How long do aluminium sliding doors take to arrive?
Aluminium sliding doors typically take 4–6 weeks to make after you sign off the surveyed specification, because each door is built to measure and powder coated to order. Fitting a straight swap of a two-panel door typically takes 1 day, and larger doors 1–2 days. These are typical times rather than promises, and we confirm a date once the order is placed.
