AI2 is a high performance insulation board manufactured from CFC or HCFC free closed cell rigid polyisocynurate PIR foam.
It’s covered one one side with an 80 μm embossed aluminum foil and on the other side with a 200 μm embossed aluminum foil.
Density of the foam: 35 ± 3.0 kg/m3
Dimensions: width and length 1200 x 4000 mm
Thickness: 20,5 mm and 30,5 mm
Main application: for the construction pre-insulated aluminum ducts for air distribution
For external use in residential/commercial and industrial buildings.

Stability to the temperature: Globe panels are used in a range of continuous temperatures normally included between -40° C and +110° C. Long exposures to the temperatures could cause deformations to the foam or to the coats, but without causing sublimation or fusion.
Aspect: prolonged exposure of the polyurethane foam to UV rays can cause surface oxidation, the phenomenon does not affect the basic characteristics and performance of the panel.
