Thanks to the complete insulation of the walls of the building against external effects in sheathing applications, the strength and durability of the building is improved. It offers a comfortable and healthy life by preventing the inflow of hot air and the outflow of cold air in the summer, and by preventing the inflow of cold air and outflow of hot air in the winter months. The energy saving achieved based on this method pays back the cost of external thermal insulation in minimum two and maximum three years. FileTex Plaster and Reinforcement Meshes are used as plaster and reinforcement mesh in sheathing applications, and TekFix dowels are used as fixation component and ProfilEx Sheathing Profiles are used as sheathing components.
