ETICS / EIFS provide exterior walls with an insulated finished surface and waterproofing in an integrated composite material system.Fiber glass mesh is necessary to reinforce the thin layer of coating applied on the insulation panels before finishing. Variations of outdoor temperature, shrinkage of the coating material during drying and displacement of insulation panels may produce cracks and clefts on the surface of the system. Fiber glass mesh solves this problem ensuring resistance and stability. Gavazzi produces several types of mesh for this purpose. Among them, Art. 0140-A and 0160-A first passed all tests carried out according to the ETAG 004 Guide issued by EOTA (European Organization for Technical Approvals), and then obtained a Quality Mark by ITC (Institute for Building Technology). The Quality Mark attests that the Factory Production Control actuated by Gavazzi properly ensures a consistent quality of the product. Use: the mesh is laid from top downwards on a fresh layer of mortar and then completely covered with the same material. The sides should overlap by at least 10 cm. Blisters and wrinkles must be carefully avoided.
