PURA System
redstone PURA™ – Naturally effective
The results are impressive: Eliminate up to 85% of heat loss, relative to the insulated wall area, with the redstone PURA™ Insulation Board. The components of redstone PURA™ are exclusively natural: Quartz sand, lime and clay. No fibers – no plastics.
Due to its capillary vapor-diffusion structure the board succeeds in absorbing large quantities of moisture and releasing it via surface evaporation and ventilation. It regulates not only the temperature balance but also the moisture balance in any building in a completely natural way.
Ratings & Recommendations
Thermal Resistance as per ASTM C518, DIN EN ISO 6946: R6.11
