Constructions
The exterior layers of fiberglass have an areal weight from 250 to 600 gr/m2.
To provide a good surface aspect is recommended to have 250g/m2 as minimum in the external layers,asthough other values are possible with glass fibers are 50mm long.
The standard material are the ones in the following list, but other designs are also available according to customer needs.
