Centre-parting sliding doors.
Centre-parting is the symmetrical Maxlight sliding configuration: two panels meet in the middle and open outwards behind a pair of fixed end panels — a symmetrical four-panel elevation that opens from the centre.
The configuration is selected for the symmetry. Where double-pane is asymmetric (one fixed, one sliding) and triple-pane is asymmetric (two slide behind a third), centre-parting reads symmetrically — the elevation when closed is balanced left-and-right, and the opening when in use is centred. It is a design language that suits classical and contemporary register equally well.
The visible aluminium signature on a centre-parting elevation is the meeting rail in the middle of the assembly, where the two sliding leaves close against each other. We engineer that joint at 46 mm — wider than the perimeter sightline because the meeting rail is doing the work of two interlocks rather than one. The 20 mm perimeter sightline matches the rest of the slim sliding range. These dimensions follow the live-site published Centre Parting specification.
Mechanically each sliding leaf runs on its own roller assembly behind a fixed end panel. Weather sealing at the centre is the most exposed condition in the range and the gasket geometry is calibrated against it; we run the same air, water and wind classes as the rest of the sliding catalogue, but the centre joint is the detail to specify carefully.
When to choose this.
01
Pick centre-parting when
the elevation is roughly four to seven metres wide and the design wants a symmetrical centre-opening expression.
02
Consider double-pane instead when
the design accepts an asymmetric one-fixed-one-sliding reading.
03
Consider pocket-doors instead when
the brief is for the panels to disappear into the wall, not stack behind fixed panels.

Frequently asked questions
What colours are available for your products?
We offer the full RAL Classic colour range (216 colours), giving you complete flexibility to match your design vision. Whether you’re looking for bold contemporary tones or subtle architectural finishes, we can accommodate your requirements.
Do you offer anodised finishes?
Anodised finishes are available on request. Please speak to our team to discuss options and suitability for your project.
What locking options are available, and can they be colour matched?
Our doors are fitted with high-quality locking systems, including bottom locks (non-PAS 24) and PAS 24-rated side locks. While the lock barrels are not colour matched, the escutcheons (visible lock surrounds) can be finished to match your frame colour for a seamless look.
What security rating do your doors have?
Our systems can be configured with PAS 24-rated side locks, providing enhanced security for residential applications.
What security certification do you offer?
We offer systems that comply with PAS 24, a recognised UK standard for enhanced security performance.
Are your warranties transferable?
Our warranties are property-based rather than person-based, meaning they remain valid if ownership of the property change
Can I view your products in a showroom?
We offer a virtual showroom experience, which can be arranged through your sales contact.
Can I visit in person?
Yes, visits can be arranged by appointment at our showroom at 333A Western Avenue, London, W3 0BE
What are your typical lead times?
Our process is carefully structured to ensure precision and quality: - Survey Stage: Approximately 1 week to carry out a site survey, provided the site is fully prepared. We’ll supply clear guidelines in advance. - Design & Drawing Stage: Around 2 weeks (or up to 3 weeks for more complex projects such as glass boxes) from survey completion and receipt of all required technical details. - Manufacture & Installation: Approximately 8 weeks from final approval of drawings, with installation scheduled shortly after. Your project timeline will always be confirmed by your sales contact based on scope and complexity.
Do you offer bi-fold doors?
We specialise in premium glazing systems that prioritise longevity and performance. Bi-fold doors typically require more maintenance due to their multiple moving parts and top-hung weight distribution. For this reason, we focus on alternative systems that offer cleaner aesthetics, smoother operation, and reduced long-term maintenance.
Will you liaise with my architect or builder?
Absolutely. We regularly collaborate with architects, builders, and project teams to ensure your design is delivered exactly as intended.
What areas do you cover?
We operate across the whole of the United Kingdom.
