SLIDING MOBILE ROOF

A motorised sliding roof, opening up to 66% of the area.

Section through the CORTIZO Mobile Roof system, official manufacturer image

A mobile roof does what a fixed rooflight cannot: it opens. The leaves slide over one another under power, and the clear area can reach 66% of the total.

The system takes three types of infill — 25 mm multiwall polycarbonate, a 24 mm sandwich panel or 24 mm glazing — and the maximum leaf size depends on the type chosen.

The relevant test for a mobile roof is not the window test but the flooding test: six hours of testing, followed by 24 hours of observation.

The data sheet for this system declares neither the extrusion alloy nor any transmittance or sound insulation values.

The thermal transmittance values published by CORTIZO are minimum values for the system, conditional on the typology, on the dimensions of the joinery and on the glazing unit. The actual value of an assembly is established by calculation, on the configuration actually ordered.

From system to finished joinery

What we do with this system

Choosing the configuration

The system offers a range; the project asks for a value. We settle the version, the glazing unit and the typology from the actual requirements of the building, not from the maximum on the data sheet.

Calculation on the actual assembly

The transmittance of a window depends on the frame-to-glass ratio. We calculate it on the actual dimensions of the openings, not on the laboratory specimen.

Our own production

Cutting, machining, assembly and glazing in our own workshop in Baia Mare, on original CORTIZO profile and with hardware approved for the system.

Installation and handover

We install with our own teams, including abroad, and hand the job over with its documents. The warranty is the one published on our warranties page.
