Beijing Tianjiang Building Materials Co., ltd is a high-tech enterprise, which produces thermal insulation building materials. The headquarter is located inside Beijing Yinghai Development Area. There is also a branch factory in Langfang of Heibei Province. Our company mainly produces TIANJIANG brand extruded polystyrene (XPS) thermal insulation board, rubber-plastic sponge, centrifugal glass wool, polyurethane foam, etc.
In 2004 from BASF chemical company in German our company introduced a production line and technology for extruded polystyrene thermal insulation board. The production line has a yearly capacity of 250000 m3 and can produces special products  such as highly flame-retardant, high compressive strength, super-thick products etc. Having durable heat-preservation and thermal insulation, unique capacity to resist penetration of water vapor, superb compressive strength, excellent sound insulation and noise reduction, TIANJIANG brand extruded polystyrene board are widely used in thermal insulation in wall, roof, floor, core material,  railway, highway, airstrip, dam, frost heat-control and air duct in central air-conditioning system.
Welcome our old and new friends at home and abroad to Tianjiang building materials Co.,ltd to cooperate with us. We will provide high-quality products and service for you.
Best and durable thermal insulation property
Tianjiang brand extruded polystyrene board ,with the conductivity factor of 0.028w/mk, has its good properties such as high thermal resistance and low linear expansion coefficient. Its conductivity factor is much lower than others such as EPS board, expanded polyurethane , thermal insulation mortar and so on. Because of its stable chemical and physical structure, it has best and durable thermal insulation property.
