01 — The solution
Six months become twelve.
Around the world, an outdoor court is usable only while the weather allows — often just half the year. Covered, it is usable all twelve months — at a higher hourly rate, in exactly the months when demand is highest.

Inside, all year
The covered season
The same venue. Twice the season.
Outside, the season ends when autumn arrives — and more and more often, summer heat stops play as well. Under the dome, play continues through winter, when players have nowhere else to go, and a controlled indoor climate keeps the courts playable through the hottest weeks.
What goes under the dome
Tennis
Football
Swimming pool
Those added months are also the ones that carry the higher hourly rate. The dome does not only extend the season — it adds its most valuable part.

Why the added months matter most
An outdoor court earns only while the weather allows. The months a dome adds are the ones when players have nowhere else to go — so demand is highest and the hourly rate is higher.
The same site, more use
Nothing is added to the plot. The courts you already have stay where they are and simply stay open all year.

The membrane
03 — Innovative membrane
Two membranes. No thermal bridges.
The dome, cut open at the ridge. Two separate membranes with still air between them — turn the model and zoom in to see how they sit.

What a thermal bridge is
In a conventional double membrane the two layers are welded together along every seam. Wherever they touch, heat passes straight from inside to outside — a thermal bridge. The air between the seams insulates; the seams do not.
How ECO Advance removes it
The outer and inner membranes are held apart over the whole surface. There is no seam that joins them, so the air layer is continuous and heat has no direct path out. This is a DUOL patent.
What ECO Ultra adds
ECO Ultra keeps the ECO Advance construction and adds a premium insulation layer inside the air space. A energy class, certified by independent European third-party laboratories.

04 — Our safety
The world changes. The dome stays.
Three real locations. Pick one and watch the dome in its weather.
Kamchatka, Russia
Up to 600 kg/m² of snow
The load sits on the membrane. The dome holds its shape.

Why it stands
An air dome is held up by a slight overpressure inside, not by a frame. Under load the membrane stays in tension and keeps its shape.
Watched around the clock
SmartDome monitors wind, snow and dome pressure, and raises an alarm when conditions change.
Three real places
Kamchatka, Dubai and Split are DUOL locations — deep snow, desert heat and storm wind, each on a standing dome.
