ISOFLEX is an elastomeric, waterborne, liquid waterproofing membrane for flat roofs. Has_x000D_excellent bonding to various substrates, such as concrete, wood, metal and any type of_x000D_waterproofing membranes and is applicable even to irregular substrates. After curing, it forms a_x000D_continuous, elastic, waterproof and vaporpermeable membrane, without seams or joints, offering:_x000D_ High elasticity._x000D_ High resistance to weather and aging._x000D_ High whiteness and solar reflectance._x000D_ Improvement of building energy efficiency by_x000D_decreasing the roof temperature._x000D_Certified according to EN 1504-2 and classified as_x000D_a coating for surface protection of concrete. CE marked. Certificate No.: 2032-CPR-10.11._x000D__x000D_Fields of application_x000D_ISOFLEX is ideal for waterproofing flat roofs, curved roofs, etc. Constitutes a simple and safe_x000D_solution for waterproofing roof details, such as corners, edges and joints between different_x000D_adjacent materials, as well as isolated cracks.
