Why choose aluminium sliding doors in Grantham?
These are the points a surveyor will go through with you when you choose aluminium sliding doors for a home in Grantham:
Whether you live in Grantham or elsewhere in Lincolnshire, 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.
For a south- or west-facing garden in Grantham, solar-control glass in the sliding panels can keep a glazed room more comfortable on summer afternoons.
- Because the panels slide rather than swing, nothing opens into the room or across the patio, leaving space for a dining table, sofa or planters right up to the glass.
- 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.
- 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.
Light and sun in Grantham
Sun angles matter for big glazed doors. Around Grantham, 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.

Rules for aluminium sliding doors 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.
Choosing the specification
- Colours. Standard shades such as anthracite grey, black and white, or a special RAL colour for an extra charge.
- Panel configuration. Two, three or four panels, with the sliding panel on the left, right or both sides to suit how you use the room.
- Threshold. A standard or low threshold, or a flush finish with a drainage channel outside where floor levels allow.
Questions about aluminium sliding doors in Grantham
Is the price different in Grantham?
No. Guide prices for aluminium sliding doors are the same across mainland Britain, including Grantham. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
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.
Should I choose aluminium sliding doors or bifolds?
Choose aluminium sliding doors if you want the most glass and fewest frames when the door is closed, and bifolds if you want almost the whole width open in summer. A slider keeps wide panels with slim meeting stiles but only opens part of the width; a bifold folds away but shows a frame every metre or so. Our sliding doors vs bifold doors guide compares them in detail.
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.
