Sliding doors for the biggest openings in the house.
MFP18, Vitrocsa and Solarlux systems, specified for new-build homes and large architectural openings: sightlines from 18 mm, panels up to 20 m², installed by our own team across London and the South East.
Four specific reasons, each one provable.
Sightlines from 18 mm
The MFP18 range shows just 18 mm of aluminium at the interlock — the slimmest sightline available on any system we install.
Panels up to 20 m²
Vitrocsa V56 and the MFP18 H-series carry panels from 15 to 20 m². These are openings standard residential doors simply cannot fill.
One team, survey to handover
We survey, specify and install with our own fitters. Flush, Part M-compliant thresholds and full project management as standard.
Published figures, nothing added
Every sightline, U-value and panel size on this page is the manufacturer's published specification. No marketing numbers.
Details, openings and architectural applications.




Brick extension, night lit. South West London.
A flat-roofed rear extension where the client wanted the wall between the brick main house and the garden to disappear. We specified the MFP18 range for its 18 mm interlock, surveying the floor build-up so the track sits flush with the finished floor inside and out.
Our own installation team fitted the run, set the flush threshold and handed over with a full demonstration of the sliding action and locking. Exterior uplights and warm interior lighting now frame the opening after dark.

Manufacture
Your system is made to order. Indicatively 10 to 16 weeks from approved drawings, depending on system and glazing; confirmed at quote stage.
Installation & handover
Installed by our own fitters, threshold set flush, full demonstration of sliding action and locking at handover.
What does it cost?
Large-format systems sit above standard residential sliding doors. The main drivers are opening size and panel count, double versus triple glazing, and corner, pocket and motorisation options.
