Stiferite panels in Polyiso foam are characterised by:
-  the highest heat insulating power with the same thickness
(see table alongside), permeability or impermeability to vapour
graded to suit application requirements
-  dimensional stability even in the presence of strong thermal gradients and of high temperatures
-  workability and light weight
-  compatibility with the environment
-  safety and harmlessness for humans
Since April 2003, every pack of Stiferite panels has borne the CE marking which certifies their conformity with harmonized standard
UNI EN 13165.

All Stiferite heat insulating panels are produced and checked, respecting the requirements established for quality management systems by standard UNI EN ISO 9001-2000.
