Redstone Pura insulation board – Perfectly natural…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 are exclusively natural: Quartz sand, lime and clay. No fibres and no plastics.
Due to its capillary vapour-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 …naturally.
