During short time they can resist also to temperatures till C, or corresponding to the temperature of fused bitumen, without particular problems. Long exposures to the temperatures could cause deformations to the foam or to the coats, but without causing sublimation or fusion. Resistance to the torch and some other reactions to fire are characteristics connected with the kind of used panel. Aspect Any possible little areas of non-adhesion between coats and foam are originated by the production process and don t prejudice in any way the physical-mechanical properties of the panels.
