3)Is high duty for temperature that reaches 220° for short periods, and 110° for long periods. (High temp. resistance). In case of using the INVERTED (Thermal in insulation over waterproofing layer) Polyurethane Boards Bears high temperature around and temperature of building roof. In summer, temperature reaches 50 – 55°, but surface temperature direct to sun is higher. Due to its high duty for temperature, the value of thermal insulation is not affected too much by this temperature.
4)For fire Resistance, Polyurethaneis self-extinguishing. If the source of flame stopped, the consistency of boards will remain unchanged besides its high duty for temperature.
5)Polyurethane Boards” are anti-acid, chemicals, bacteria, parasites and strong solvents.
6)Stability is excellent. are anti-acid, chemicals, bacteria, parasites and strong solvents.
7)Water Absorption reaches a little more than 1 % for boards without facing in spite of that, boards don’t keep water more than 4 – 5 days. Range of water evaporation is very high 2.5 times than polystyrene.
8)Polyurethane Boards are covered (both sides) with material resisting for ultraviolet rays, water absorption and humidity.
9)Guarantee 30-35 years.
