RULES TO PREVENT HEAT SHOCK OF THE GLASS IN SHOP AND OFFICE WINDOWS
In any case that the glass receives solar energy (infrared radiation), it is not appropriate to put on stickers or any type of curtains like stores, at a distance less than 10cm from the glass. Otherwise, there is a potential heat shock problem and, therefore, breaking glass.
Also, it is not indicated to use any kind of awning (natural or artificial), as to be shadowed the half glass, while the other half is exposed to sunlight. In this case, there is, again, the possibility of heat shock pane.
Also, it is not allowed to have heating elements close to the glass pane or infrared radiation from the heating elements to be directed through the pane.
Finally, all the glasses in the windows should be laminate (triplex). Doors and skylights Securit should be applied. The struts should be, at least, 10+10 Laminate & Ronte Care from both sides. In any case, they should withstand 12 bf wind.
The issue of the anti-theft or the bulletproof glass is another study and has different requirements.
