Does BITULINE water insulation covers melt in hot weathers?
BITULINE®  is applied through melting by welding torch. The melting temperature during application is at least 250°C. In areas where the temperature under shadow reaches 50-55 °C the heat on the roof surface never exceeds 80-85 °C. Thus, the BITULINE water insulation covers applied on the roof do not melt. BITULINE may soften due to heat but this situation does not cause corruption on the surface.
