Hemp Insulation Technical Sheet-1

Black Mountain Hemp Insulation Technical Data Hemp insulation is a natural plant fibre material with excellent insulating properties that ensure a thermal conductivity of 0.039W/m².K. This product is suitable for loft space, suspended floors, partitioning walls and Technical Sheet timber frame structures. Hemp insulation is a natural fibre material which is safe to install without protective clothing. Hemp has the ability to help manage condensation levels which not only decreases the risk of moisture damage but also improves indoor air quality by allowing the building to breathe. Black Mountain hemp insulation is a dense thermal insulator that can guarantee reduced heat loss, lower energy costs and a consistent internal temperature. Hemp fibres are incredibly durable which means that the product has the capacity to span the entire life of the building.
