Laminated glazing

Laminated glazing is made up as follows: thickness of the 1st piece of glass (in mm), thickness of the second piece of glass, number of interlayer coatings. For example, 44.2 laminated glazing is made up of two 4 mm pieces of glass assembled with an interlayer of 0.76 mm (or 2 x 0.38 mm). The choice of composition depends on the desired performance.
In the event of impact, the glass may break but most of the fragments remain attached to the interlayer.
There are 3 families of laminated glazing :
- laminated glazing with standard interlayers,
- laminated glazing with acoustic interlayers,
- laminated glazing with stiff interlayers,
Different types of interlayer can be used (PVB, EVA, Ionomer).
CEKAL certification focuses in particular on:
- the quality of the laminated glass assembly (resistance to high humidity, high temperatures, UV)
- security performance ratings (optional).
