Description
This is industrially produced glass on whose surface metallic oxides are powdered so as to obtain a very thin layer (from 0.01 to 0.8 micro-metres).
This brings about a change of the behaviour of the glass in relation to sunrays, both visible and infrared.
It is used for the production of shields which can meet the needs, at the same time, in relation to:
- Solar energy control;
- Luminosity control;
- Aesthetics;
- Economy both for heating and cooling of the air (low compliance glass).
The applied layer consists of several superimposed films (up to 15):
- One film which ensures adhesion to the glass;
- One of more films which gives the glass the required characteristics;
- One chemical and mechanical protection film.
