Printig it is based on Aluminium flake disperse on water resistant resin and guarantee up to 72h of immersion without loss of adhesion after adhesive tape peeling test.Pattern, shape of printed elements and percentage of printed area can be according to customer request, provided the engraving of the cylinder.
The most used patterns are on round silver dots, because of the silver reflectance to solar radiation, percentage of printed area is evaluated to fulfill with Heat Solar Gain Factor request.
PATI printing process derives from a specific research; color tonality and adhesive tape peeling resistance has been tested after XENON accelerated weathering exposure under full sunlight spectrum Arc lamps
50 W/sqmt, (UNI EN ISO 4892-2) for more than 3000 hours, the change of color is negligeable.
For welding purposes print can be easily removed using Ethyl Alcoholor Methyl Ethyl Ketone.
In any case the printed layer shall be placed at the inner side of the roof or facade in order to be protected from wind, sand and accidental events.
ARCHITECTURAL INSTALLATIONS
Multiple layers air inflated cushions: this solution allows to reduce the “U value”, or Global Heat Exchange Coefficient. Indicative values are as follows:
- Single layer = 6,0:6,2 W/sqmt/°K (lower values for pigmented or printed film)
- Two layers = 2,58:2,80 W/sqmt/°K (lower values for pigmented or printed films)
- Three layers = 1,67:1,83 W/sqmt/°K (lower values for pigmented or printed films)
- Single layer: this solution is considered as a tensostructure, and a system of steel cables has to be engineered to stabilize the film against wind and accidental loads.
