New energy-saving material from USA

Compound glassfiber boards :
　　
Glassfiber has a history of more than 50 years for commercial use.It has become one of the most useful and contributory man-made materials in the world by its advantages of sound absorption,warm air or cold condensation control and removal of impurity in liquid and gas.
　

Compound glassfiber board is the insulation material made by pressing inorganic glassfiber and thermosetting resin,mainly used in controlling temperature and sound in household buildings,commercial buildings and industrial buildings.The glassfiber board with surface mounted with high strength fire-proof aluminum foil and interior wall coated with anti-biotics glassfiber felt is specially used in super energy-saving ventilating tunnel for treatment of air.The application of this kind of boards saves energy equivalent to 4 billion barrels of oil for USA every year,and also helps in protectingthe environment.
　　

Compound glassfiber board is the main part for super energy-saving ventilation tunnel,with the shapes of rectangle or polyhedron,applied in air-conditioning system.

Main characteristics of super energy-saving air pipes:
　

Super energy-saving air pipe is sealed with high temperature sealing material.The good sealing system can reduce heat or cold loss,save energy,reduce running cost effectively.It has special properties of sound absorption,can absorb machine noise and air noise,remove the noise coming out of shrinking of metal air pipe system,make your environment quieter.It has specially reinforced surface,can bear the max.safe pressure of 996 Pa and wind speed of 25.4m/sec,improve air quality.Its performance has exceeded that of all metal air pipes.Its advanced design avoid completely moisture condensation by metal air pipes.It has ligh weight,can reduce load of buildings effectively.In terms of installation,it can reduce labor strength dramatically(only 1/10 of that spent in installation of metal ones).And it has good temperature resistance(as high as 121℃).
