The standard thermally broken slider, with up to 6 leaves and the option of retracting into the wall.
4200 is the standard slider in the range: a slim sash, of 33 or 37 mm, frames available in six dimensions and the possibility of going up to three tracks. It is the solution for ordinary balcony and terrace openings, where leaf weights of hundreds of kilograms are not required.
One peculiarity of the data sheet is worth noting: the maximum leaf weight is declared differently according to the angle at which the leaves meet — 100 kg at 45º and 200 kg at 90º.
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.
