Application

Glass Wool are widely used in public, commercial and residential buildings as well as industrial plants, for applications such as roofing, external wall, partition wall and floating floor to provide fire protection, thermal insulation, acoustic control and condensation control.

Q: What's the difference between the rock wool and glass wool?: Glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. Taking quartz sand, limestone, dolomite and other FIR stone as main raw materials, and is melted into glass after mixed with some pure alkali, sodium borate and other chemical raw materials. In melting state, transfer them into flocculent fibers under the effect of external force, fiber and fiber are in three-dimensional crossing and winded with each other, presenting many little gaps. The gaps can be regarded as air voids. Therefore, glass wool can be regarded as porous materials, it has good heat insulation and sound absorption performance. Glass wool is a kind of spongiform material shaped by making melten glass fibering, it's chemical content belongs to glass and is a kind of inorganic fiber. It has good molding, small bulk density, low thermal conductivity, good thermal insulation and heat insulation, good sound absorption, corrosion resistance and stable chemical performance. Rock wool is artificial light silicate, not the continuous flocculent fiber material, soft texture, good chemical stability, acid and alkali resistant. Not brittle or pulverization, good elasticity, it can be heat insulation, sound insulation in projects.

Q: How much is the unit weight of thermal insulation glass?wool?boards at least? How much is the unit weight of sound absorption glass panels?: They are from twenty to less than eighty.

Q: What is the difference between imported glass wool and rock wool?: Glass wool is categorized into glass fiber, which is a manmade inorganic fiber. Glass wool is a material which fibering melting glass to form cottony shape. Its chemical composition belongs to the classification of glass, being an inorganic fiber. So, it is good shaped with small volume density, low thermal conductivity, good thermal insulation and sound absorption properties, great corrosion resistance as well as stable chemical performance. Rock wool board is a manmade inorganic fiber which employs basalt as the material and is produced by melting process at high temperatures, keeping light in weight and low in small thermal conductivity with the features of heat-absorbing and non-flammability.

Q: How to conduct thermal insulation construction of external wall glass wool?: Construction recommendations: Installing metal frameworks in the floor and in their corresponding roof, trying to ensure that the framework should be perpendicular to the floor; erecting metal framework in the location apart 60cm from the metal frameworks that have been placed; pasting gypsum board on one side of the frameworks and fix it to the frameworks; putting glass wool in the gap of frameworks; pasting gypsum board on the other side of the frameworks.

Q: Is glass wool felt the mineral wool felt?: No.

Q: Choosing glass wool with proper thickness for piping insulation of Dn900 boiler room.: If using glass wool, Dn900 pipes must be equipped with insulating layer which is equal to or greater than 100mm. The best working temperature of glass wool does not exceed 300 degrees. Glass wool should keep 0.035 to 0.046 in thermal conductivity. The best working temperature of glass wool does not exceed 300 degrees. It will generate good effect if using aluminum silicate or silicate. Silicate is a closed-cell insulation material with high temperature resistance, so silicate is the most energy-efficient material.

Q: How is the insulation property of glass wool color steel?plate?: Glass wool thermal conductivity coeffieciency is 0.043. rock wool is 0.041 with better thermal insualtion. Since the insualtion and fireproof properties of the rock wool are better than the glasswool, rock wool is more expensive. rock wool is operated at construction site while glass wool is directly operated in the production line.

Q: How about the thermal insulation performance of glass wool?: It is good. The heat conductivity coefficient of glass wool is 0.043, the heat preservation property of which is less than that of rock wool of 0.041. The thermal insulation performance and fireproofness are better than that of glass wool, but the price of it is also higher than that of glass wool. But the site construction operation of rock wool is not as good as that of glass wool. If it is a direct composite of production line, then it has nothing to worry about.

Q: How is the prospects for rock wool board and glass wool board?: They are very good, but they also cause great pollution. Such problems as how to dispose of abandoned materials and excessive materials and how to recycle these materials are very difficult to deal with.
