3), poor combustion performance, EPS materials lead to abnormal level has been in the fire Beijing Radio is very low since the combustion properties of EPS caused. 4), environmental, xps extrusion board 10mm, EPS in the production process is not environmentally friendly, would exclude a lot of waste and gas, have a great impact on the surrounding environment. 5), poor thermal conductivity, xps extrusion board, leading to 75 in line with our current promotion of energy efficiency standards, xps extrusion board 50mm, basically belong EPS insulation material is being phased out. Building roof insulation, steel roofing, building wall insulation, building ground moisture, the square ground, ground frost heave control, central air conditioning and ventilation pipes. Decorated line angle 1) According to the design requirements for ink lines position to do pop line angle, and horizontal and vertical correction. 2) Use the slotted groove angle will board cut notches, notch thinnest at not less than 15. 1), XPS board has a dense inner surface and closed cell structure. Its thermal conductivity is much lower than the same thickness of EPS, xps extrusion board b2, compared with EPS and therefore has better thermal insulation properties. For the same building facades, its thickness can be less than other types of insulation materials. 1), high intensity XPS board itself, resulting in a more brittle sheet, easy to bend. 2) higher prices compared to the EPS system.
