Features and Benefits of Polyurethane:

Low thermal conductivity factor (k = 0.016 kcal / m.h ° C), allowing to achieve double the thermal efficiency that would be obtained with any other insulating material, implying a reduction of about 50% of the thickness to be used in relation to the other materials.
Meets ASTM-C-591 standards, exhibits good chemical resistance to most solvents and reagents, does not rot, does not mock and is not attacked by insects and rodents.
It can be supplied with flame retardant, providing safety to the applicator and to the company.
