Permasteelisa’s quaternario system enables efficient facade refurbishments by replacing old cassettes with upgraded double-skin Closed Cavity Facades (CCF), transforming static glazing into dynamic, responsive systems with improved performance.

Project information
In the period 1995 to 2010 Permasteelisa made several projects using a quaternario system. This system uses a carrier frame and a cassette with insulated frame, double glass and gasket fixed to the carrier frame. This system proves to be very suited to be upgraded during refurbishment of facades. By removing the old cassette and replacing it with a new one all materials with limited life spans can be removed. In this study the new cassette was a designed as a double skin. Meaning an external single glass layer, a cavity with automated venetian blind and an internal double glazing. This was made as a Closed Cavity Facade. Advantages are that we can replace a traditional static double glazing with a responsive dynamic system CCF.
