Why ZEN by NUMAEX
ZEN is a heavy pivot door system engineered for grand thresholds. Floor-to-ceiling proportions, a slim aluminium-alloy profile only 5mm thick at the wall, and a concealed pivot mechanism deliver a door that reads as a single sheet of glass held by hairlines of metal — and behaves like a piece of architecture. Up to 14 feet tall, 7 feet wide, and 350 kilograms in weight, ZEN moves with the quiet authority that only properly engineered hardware allows.
The system is built around a world-class pivot platform trusted on the most demanding architectural projects globally. Concealed at floor and ceiling, the pivot delivers smooth, controlled motion across spans where conventional hinges would fail. The result is a door that opens with a single fingertip and closes without sound, regardless of leaf size or specified glass thickness.
ZEN reveals itself not through ornament, but through presence. Drop seals and air seals integrate within the slim profile, delivering acoustic and thermal performance without visual disruption. Profiles arrive in brushed aluminium as standard, with bronze, blackened, and bespoke RAL finishes available. Glass is specified from the full NUMAEX range — clear, bronze-tinted, smoked, low-iron, or reeded privacy. Every junction is detailed for a clean line; every fitting earns its place.
ZEN is engineered in-house to a tolerance most markets do not specify and most installers cannot deliver. Profiles are extruded and finished in our own facility, the pivot platform is calibrated per leaf weight before it leaves the workshop, and every door is dry-assembled and rotated through its full arc before crating. The result is a door that arrives on site ready to install and ready to last — engineered for decades of daily use without adjustment.

What is inside a Zen
Grand Residential Entrance
Where the front door of a private residence is expected to perform as architecture rather than as ironmongery, ZEN sets the threshold. A 14-foot leaf in clear toughened glass admits the full reading of the entrance hall at first sight, while the concealed pivot moves a 350-kg panel under fingertip control. Drop seals and air seals integrate within the slim aluminium profile so weather and acoustic performance match the quietness of the entry. The door is the first material decision a guest experiences — and the one that establishes the standard for everything that follows.
Engineered to support, designed to vanish.
Every line, every joint, every hidden layer is crafted with intention. Behind its minimalist form lies a structure of quiet resilience. From 5 mm profile edges to internal metal bones, Zen is built to hold glass up to 350 kg with clarity and control, on a pivot system trusted by the world's finest architectural projects.
