Build healthy, breathing houses for the world
Basic introduction breathing paper is a foreign name (dupont) , also known as Dike waterproof breathable film in China, is the use of a special new type of polymer material, the surface of the material has its tiny pore structure, because the water droplet small diameter of about 0.02 mm, the diameter of the water vapor molecule is only 0.0000004 mm, the diameter of the two have a huge difference, according to the concentration gradient diffusion principle, water vapor can freely through the micropores, because the surface tension of liquid water and water droplets can not pass through the breathing paper material, therefore, breathing paper excellent waterproof performance and permeability. The waterproof breathing paper is mainly used for the foundation of building protection such as wood structure and steel structure. The breathing paper has better waterproof performance, and is tightly wrapped around the building to protect the building from the erosion of rain water, effectively ensure the service life of the building. Breathable breathable breathing paper provides excellent water and air isolation and Balance Adjustment of water vapor transmission. It can reduce the chance of external water vapor entering the cracks in the wall, at the same time, the moisture inside the building can escape from the wall, effectively avoid mold and condensate in the wall and roof of the generation, to ensure the effectiveness of thermal insulation materials play, so as to achieve energy saving, improve the role of building durability. Enhanced breathing paper (W 5, R 8) : Hurricane Resistant, provides excellent water and moisture permeability and tear resistance, suitable for use in hurricane and severe weather areas, but also suitable for roof use.
