The saturated asphalt felt behaves as an excellent hydraulic insulation. As a cellulosic base, it absorbs the condensed ambient humidity in the wood, as a result of the difference between indoor and outdoor temperature (according to IRAM 1582 standard, it can absorb up to 25% of its weight). Allows the water vapor generated in the environment to go outside, not being trapped in the roof. It allows the wood to breathe, not altering its original characteristics, which ends destroyed by the proliferation of fungi caused by moisture.It is the only product for this purpose that complies with IRAM and international standards.
