High performance natural insulation Black Mountain ThermalFlex is a high performance plant and wood fibre insulation and a natural solution to insulating traditional, new build and Passive House properties. Its high thermal mass enables it to store thermal energy and flex the re-emission of energy back into the building; saving energy and reducing costs. warmer safer smarter A combination of natural fibres provides sufficient flexibility to simplify installation whilst maintaining enough rigidity to prevent slumping in vertical walls. In addition to external timber frame walls, ThermalFlex is...

This delayed heat transfer creates a "thermal time lag" in summer months, reducing the requirement for air-conditioning during peak temperatures at midday. In the evening the stored energy is released internally, acting as a passive heat source for the building. In winter months, the solar gain can be very significant due to the inclination of the sun; a typically south facing window can absorb up to 32kwHr per m². How thermal mass reduces internal temperature fluctuations ThermalFlex acts as a passive solution to condensation control, improving the internal atmosphere of a building. Longevity...

ThermalFlex insulation matches the following standards for loft, rafter, external and internal wall thermal requirements as follows: Sustainable design Black Mountain ThermalFlex offers a number of performance and environmental benefits, which include: Wood fibres used in production are taken from recycled wood products. CO2 is permanently locked up during the growth of the fibres. Zero waste policy – all natural fibres used in production are recycled. 90% less energy used during production in comparison to some man-made insulations.
