The 75 mm profile with Performance hardware, the only one in the range classified for wind in Class E2600.
COR 75 Performance is the system that takes wind resistance furthest in the whole CORTIZO window range: Class E2600, against C5 for the other families. It is the argument for tall buildings, exposed locations and façades with large openings.
The two versions — concealed sash and visible sash — have the same declared transmittance, but differ significantly in glazing rebate, leaf weight and watertightness.
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.
