Q:What are the construction methods of glass?wool?board used in external wall?

It should be more convenient to use glass wool that can be sprayed on other items.

Q:Can high-temperature glass wool be on fire?

Glass wool will not catch fire because it beongs to Class A non-combustible products. It will carbonize but not burn if the fire is big and burning time is long.

Q:What is the difference between glass wool and rock wool insulation board insulation board ?

Glass wool is an artificial inorganic fibers, a kind of glass fiber. glass wool is mainly made of natural ores such as quartz sand, limestone, dolomite , added with some pure alkali, borax and other chemicals and melting it into class and fibrating the molten glass, thermosetting resin-based environmentally friendly adhesive binder, an inorganic fiber. Glass wool is good-shaped, low bulk density and thermal conductivity, thermal insulation, sound-absorbing properties, corrosion resistance, chemical stability and other characteristics; typical of porous sound-absorbing material with good sound absorption properties. Rockwool: English name(rockwool), belongs to the inorganic material, using basalt, dolomite as the main raw materials. By high temperature melting, man made inorganic fiber by the high-speed centrifugal device with a strong fire insulation properties.

Q:How many types of centrifugal glass wool?

Glass wool belongs to a category of glass fibers, and it is a man-made mineral fibers. Glass wool is melten glass fibrosis, cotton-like material, and the chemical composition is metallic glass type, and is a inorganic fiber having good shape, bulk density, low thermal conductivity and thermal insulation and heat insulation, sound-absorbing properties, corrosion resistance and chemical stability.

Q:How about the sound insulation performance of glass wool felts?

The direct relationship between sound level and the density of glass wool. It has sound absorption penetrability, also can be wall.

Q:Which is more effective in retarding fire, rock wool or glass?wool? What is the difference between rock wool and glass wool?

In terms of fireproof effect, rock wool is certainly better than glass wool. The maximum temperature of rockwool is 1100 ℃, and glass wool is only 600 ℃. In addition if used in the external walls, the highest unit weight of glass wool can only be in the range of 60-90, but rock wool can be over 140. Generally glass wool can not be used in external wall at present. Only rock wool is A grade fireproof material.The heat conductivity coefficient of glass wool is lower than glass wool and the fibre length of rock wool is longer than glass wool. As for price, tons of glass wool rock is more expensive than that of rock wool. However, if counted by square size, glass wool is cheaper per square size than rock wool.

Q:Is centrifugal glass wool board suitable for home use?

It can be easily broken and produce fine suspended particles. If the glass wool is of poor quality, you'd better use plastic bags or non-woven fabric to wrap it when using. So you must choose brand whose products are of good quality. Also if it is for the acoustics, it will do harm to the human body if inhaled into the lungs. So be sure to choose a renowable brand o centrifugal glass wool.

Q:What's the difference between the rock wool and glass wool?

Glass wool: Main raw material is glass, A level fireproof grade, thermal conductivity coefficient 0.037, thermal shrinkage temperature 270 degrees, application: obvious cold insulation effect. Rock wool: Main raw material is glass, A level fireproof grade, thermal conductivity coefficient 0.040, thermal shrinkage temperature 730 degrees, application: It'd used in construction, ship building, petroleum chemical and other high-end engineering. hope it can help you.

Q:Which one among polystyrene?boards, rock wool boards and glass?wool?boards is the best materials for external wall thermal insulation?

According to the "Provisional Regulation of Civil Building External Thermal Insulation System and Exterior Wall Decoration Fire Prevention" issued by Ministry of Public Security and Ministry of Housing and Urban-Rural Development, the fireproofing performance of it should not be lower than B2-level. Rock wool board and glass wool are both accessible if taking cost into consideration. The combustion performances of polystyrene?boards are generally C- and B1-level, while the combustion performance of external wall thermal insulation materials should be A-level.

Q:How is the prospects for rock wool board and glass wool board?

It is good.Some countries control the use of extruded polystyrene board.Moreover, no new and better energy-saving materials emerge.Therefore, these two materials will be more widely used.
