Unrivalled Weatherproofing

The double-faced Siccόna structural system offers guaranteed all-weather protection - thanks to the almost full coverage of its exterior glazing, heavy duty EPDM-type perimeter seals, as well as its integrated steel perimeter multi-locking Roto mechanism (opening system) or the ultimate smooth installation offered by Hautau rollers (sliding system).

And even where Siccόna double glazing systems do not use Argon, an automatic two-way valve is used to stabilise internal pressure of the gap between the panes of glass and external atmospheric pressure when the pressure difference between them exceeds 80 millbar.
