According to the the WPC Professional Committee

Can be made of polystyrene foam (EPS), the continuous extruded polystyrene foam (XPS) insulation performance, as technically ripe for energy-saving building materials, mainly used in the construction of walls, roof,places such as windows, doors and ground. EPS, XPS foamed magnification up to 50 times, EPS98% of the volume of air, only 2% of the material, is a fixed air, shock, saving resources, excellent material, with an average load 5 tons per square meter. In addition, microporous plastic with excellent performance, fatigue life increased by 4-7 times 6-7 times higher impact strength than traditional insulation materials, to speed up the process of industrialization will be a major breakthrough in energy efficiency (insulation, thermal insulation) materials. affordable composite/pvc decking
According to the the WPC Professional Committee of CPPIA vice president, chairman of Beijing of Futuresoft Technology Development Co., Ltd., Dr. Song Weining, phenolic foam in recent years developed a new type of material, its flame resistance, low smoke and high temperature stable performance, the adiabatic insulation, sound insulation, easy molding, better durability, and is known as the third generation of emerging insulation materials. In the next few years, phenolic foam, the output value will be the average annual growth rate of 20%.
China is the world's first large windows and doors production and user countries, doors and windows of the demand growth rate of 11% per annum in the doors and windows of the annual new housing demand of more than 500 million m2, while the existing building renovation demand for energy-saving windows and doorsover one billion square meters, Fenestration annual total consumption is equivalent to four times that of Europe. where to buy cheap composite decking
It is understood that the plastic doors and windows, energy efficiency is very prominent, with insulation, sound insulation and moisture characteristics. In the heat transfer, the thermal conductivity of plastics only steel 1/360, 1/1250 of the aluminum, has good insulation properties. At the same time, the plastic doors and windows profiles are multi-chamber structure, make full use of the thermal insulation properties of air, and further reduce the thermal conductivity of the material as a whole. In airtight performance, the plastic door sash feed or fan material between by melt welding, window frames, sashes are a whole, there is no gap between the horizontal and vertical material eliminate the air through the corner of the cross feed and vertical feed stitching possibilities.
According to information available, the plastic profile manufacturing has great advantages in energy saving, from raw materials to produce the whole process of the product point of view, the production of one ton of plastic profile than the production of one ton of aluminum saving 10,000 kwh left and right, and more to produce 1 ton of plastic profile can save 3.6 tons of coal, to reduce the CO2 emissions of 9.43 tons, 30.6 kg to reduce the emission of sulfur dioxide gas, to reduce the emission of nitrogen oxide gases 26.64 kg. backyard patio wpc decking
Wood-plastic composite material is a new type of green building materials, surface appearance, good performance, workmanship, form complex, has a huge market for building materials such as doors and windows, decorative, pinch, template, curtain wall application. Wood plastic aluminum composite windows and doors insulation coefficient over the thermal insulation requirements of the building windows and doors for Beijing, Tianjin, and therefore can play an important role in building energy saving.
The insulation properties of wood-plastic composites significantly better than insulation broken aluminum alloy, avoid aluminum doors and windows difficult to solve indoor condensation leakage problem; whole window wind pressure, water tightness, air tightness performance steel doors and windows, and to avoid the window deformation; weather and useful life than steel doors and windows. In addition, wood surfaces can be processed into solid wood, metal, marble and other effects, decorative aluminum and steel doors and windows. Production of wood-plastic products can be used more than 98% recycled materials, and can be 100% recycled, waterproof, does not rot, anti-moth-eaten, salt, acid, maintenance-free, free paint, formaldehyde and other characteristics, and therefore in the building materials field meteoric rise, promotion and development in China. In his view, energy saving and environmental protection, the development prospects of the wood-plastic composite materials can be expected. backyard patio wpc flower boxes
