There is a smooth enhonced aluminum foil dampproof face on WAHLEE glasswool pipe shell. Glasswool pipe shell is antisepsis, non moisture absorption, no smiley, no moldy with no germs propagation. The materials are suitable for temperature keeping of heat pipes, cooling pipes, hidden and outside pipes. It has passed the all the indexes of incombustible materials in standard GB/T5464-1999. Effectively prevent the cooling, pipe freezing and pipe noise controlling by using the thickness and surface materials with attention in the sealed processing between joints. Such as the glasswool pipeline in Unit Weight: 64kg／m3 Thickness: 50mm can reduce 28 db noise in average.

Usage
It is widely applied for temperature keeping, heat insulation and sound absorption in business building, industrial establishment, civilian building and power plant as well as various air condition system and industrial pipeline system.
