Many things are checked in the windows and glass walls (vitrines). Some of them: scratches beyond what the standard allows, glass that is not to standard, unsuitable seals, water penetration and more.
Scratches
The Israeli Standard for glass requires that there be no scratches visible in reasonable lighting from a distance of 3 meters. Sometimes the glass gets scratched during construction, and at handover to the residents it is so dirty that the scratches cannot be seen. Usually they are noticed only after cleaning. In such cases there is no choice but to replace the glass.
Glass that is not to standard
The requirements of the Israeli Standard on the type of glass are strict, according to where the glass is located.
Glass below a height of 1.05 meters must be safety glass: glass that will not break easily if someone bumps into it, and that will not cause injury if it does break.
Water penetration
There are several possible reasons for water getting into the building through the windows.
The most common is a faulty connection detail between the aluminum frame and the stone cladding around it. This detail must prevent water from getting in at the sensitive joint between the stone cladding, or other cladding, and the aluminum frames. You can also read about dampness that gets in through windows on the page dampness in buildings.
