AEFAST WALL designed and produced for renovation acoustic insulation. This product is the best when it comes to comfort and functionality in cases where the partitions clean-up need a higher acoustic insulation. AEFAST WALL, absolutely innovative, adds up an elastic and sound-impeding layer of elastomeric compounds coming from the recycling of ELT bounded by polyurethanes (750 Kg/m3 density, 4-10-20 mm thickness), to a plasterboard panel (dimension 1200mm x 2000mm, thickness 12,5 mm). The sound-impeding layer thickness can vary between 4 mm, 10 mm and 20 mm depending on the acoustic performance we would like to obtain. The application is incredibly simple: direct fastening on existing walls. To improve the construction and the acoustic performance an additional plasterboard panel is enough. AEFAST WALL is the successful merger of experience, simplicity, research and technology in a one product with great characteristics.
