For screed coats, up to 5 cm thick, as an alternative to the traditional electro-welded grids it is possible to use dedicated fiber glass meshes, acting as reinforcement, stabilization and anti-cracking elements. Fiber glass meshes offer several advantages: they are light, easy to transport, cut, handle and install on site. The mesh must be embedded with care, creating a "sandwich ‘in the screed. On each side, the rolls should overlap at least l0 cm. Available in different mesh sizes (up to 4 cm) they are provided either in traditional ‘E’ glass yarn or in special ‘AR’ (Alkali -Resistant) glass yarn, granting high performances in cementitious material environments.
