, Strength: The strength should be noted here tensile strength, density and tensile strength of polystyrene board have absolute relationship, the average EPS density 18Kg / m3 tensile strength of 110 ~ 120KPa, 20Kg / m3 density at 140KPa about. XPS normal bulk density from 38Kg ~ 45Kg, intensity from 150KPa ~ 700KPa or higher insulation board manufacturers, compared with EPS, XPS board strength higher Yantai insulation board manufacturers, so when the outer brick veneer is relatively stable or XPS system , and its load-bearing capacity is higher than the EPS system. 3. Weather resistance: Weathering refers to the insulation system for the outside world the ability to adapt to climate change, refers to the different climatic conditions, the overall stability of the system, the insulation effect if there is a series of issues related to quality changes. Weather resistance is a very important indicator of the insulation system. Because compared with EPS board XPS has high water absorption, so his durability is better than XPS system now mature exterior insulation system are taken into account in each layer waterproof, because after absorbing weather insulation performance will be greatly decline. Because EPS relatively strong water absorption, water can reduce the insulation properties, the sheet material softened, plus their strength is relatively low, the construction of the weather when high Hengshui insulation board manufacturer, if suck water in the construction is not yet complete drying dry, his weaknesses revealed beyond doubt. If the exterior wall leakage point again, EPS dangerous. The so-called exterior insulation, refers to the outer surface of the vertical external wall insulation construction. I believe that the function of insulation, wall insulation is limited to increasing the effectiveness and resulting requirements, and should not count on the stability of this layer of insulation structure play a role in the body wall; the main wall, the exterior insulation layer The substrate must meet the requirements of the mechanical stability of the building, can withstand a vertical load, wind load, and can withstand impact and safe to use, but also make the surface of the insulation layer and the decoration layer can be firmly fixed on its cover. Of course, for exterior insulation and finish systems, in terms of the composition of materials, systems design, application, experimental research and other construction there are many erroneous understanding, these four basic errors directly affect the depth exterior insulation technology and the development of Tai'an insulation board manufacturers, should be taken seriously enough. External thermal insulation system specific studies and operations, as well as a business conscience and social responsibility issues, while the government should take effective measures to properly guide the direction of development of exterior insulation, exterior insulation effectively get rid of the current market, "design look safe the owners look at the price, the total package look rebate, supervision see red, "the unspoken rules and rules of the game.
