Aluminium windows and doors

Shading and solar protection

Fixed and adjustable solar shading louvres, decorative lattices, Mallorquina shutters and terrace enclosures.

Solar radiation is controlled most effectively before the light reaches the glass. The systems below are declared on wind resistance and on the maximum free span of the louvre.

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.
