Why choose aluminium sliding doors in Marlow?
The right door depends on the opening, the room and the way you use the garden. Here is how aluminium sliding doors tend to work out in practice:
Before aluminium sliding doors are ordered for a Marlow home, the survey should check the opening width, floor levels and existing lintel, so the quote reflects the real job.
Whether you live in Marlow or elsewhere in Buckinghamshire, 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.
- 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.
- 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.
- 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.
How much sun will a door in Marlow get?
At the latitude of Marlow, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 49 min against 16 h 39 min in midsummer. A south-facing aluminium sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.
What should you budget for aluminium sliding doors in Marlow?

How fitting works in Marlow
Surveys in the SL7 district are booked at a time that suits you. After you approve the quote, manufacture is typically 4–6 weeks from survey sign-off; on fitting day the old door comes out, the new frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 1 day for a two-panel straight swap; 1–2 days for larger doors.
Do you need approval in Marlow?
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
- 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.
- Dual colour. A different colour inside and outside, so the exterior can match your windows while the interior suits 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 Marlow
Can you match other doors and windows in my Marlow 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.
How do you look after aluminium sliding doors?
Aluminium sliding doors need little care: wash the frames with mild soapy water a few times a year, vacuum grit out of the bottom track and keep the drainage slots clear. A light silicone spray on the locking points once a year keeps them smooth, and rollers can be adjusted if a panel starts to drag. Manufacturer guarantees on frames, hardware and sealed units are passed to you, and our workmanship guarantee is set out in writing in your quote.
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.
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.
