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.

Highly suitable for historic structures where breath ability is essential.
Thermal Resistance as per ASTM C518, DIN EN ISO 6946: R6.11
Mould Resistance as per ASTM 3273, ASTM G-21: Highest possible score.
