Inclined glazing on a 52 mm mullion-and-transom frame, with a pitch between 12% and 85%.
The veranda system uses the same mullion-and-transom principle as the 52 series façades, but applied to an inclined surface. The permitted pitch is wide — between 12% (7º) and 85% (40º) — which allows both almost horizontal rooflights and verandas with a steep roof.
The glazing rebate is declared separately for the fixed lights and for the roof window. The assembly is tested to the curtain wall standards, and the projecting opening has its own, more severe, set of classes.
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.
