BLACK-STYR UNIVERSAL EPS 100 031 graphite polystyrene is a top-class, unique, and versatile thermal insulation material for the construction industry. In addition to the typical properties of graphite polystyrene, which allow for reduced board thickness and are designed for passive and energy-efficient homes, BLACK-STYR has been enhanced with features such as water resistance and improved insulation parameters. Its excellent thermal conductivity coefficient of λ ≤ 0.031 [W/(MK)], water resistance – WL(T)4, flexural strength BS 150kPa, and compressive strength 100kPa allow for a wide range of applications, including foundations, floors, floor underlays, roofs, solid and ventilated flat roofs, and all types of facades and building facades. It is recommended for areas where reducing insulation thickness is a good solution, such as windows, balconies, and terraces. The high quality and class of polystyrene will contribute to a long-term investment in the form of reduced heating costs, and its selection will be an excellent solution for modern construction. BLACK-STYR UNIVERSAL EPS 100 031 polystyrene boards are available in dimensions of 500×1000 mm. Standard thicknesses range from 10 mm to 300 mm in 10 mm increments. Larger boards are also available upon request, as well as milled boards from 50 mm thick. This universal, waterproof graphite polystyrene with enhanced parameters is intended for construction as a modern and energy-efficient thermal insulation. Polystyrene for demanding customers who value and prioritize quality.
