Q:Sound absorption and sound insulation How is the sound insulation effect of glass wool?
The sound insulation effect of sound-absorbing and sound-insulating glass wool is very good. Firstly, the quality of wall is good and durable; secondly, the sound insulation effect is very good, mainly because the sound absorption property of glass wool is good, which can cut off external sounds effectively.
Q:Can glass wool be used in exterior wall for thermal insulation?
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. Glass fiber cotton, if used in buildings, its surface always is attached to veneer with somewhat certain acoustic transmission effect, such as of plastic film, metal screen, window screen, fireproof cloth, glass cloth and other materials with less than 0.5mm, basically able to keep the original sound absorption property.
Q:The glass wool board of Kunnai Building Materials Corporation have different densities. Are there any differences?
Of course there are differences on attrition rate, and this is the same as rock wool. This will affect the schedule, especially will add construction difficulty. They are all inorganic materials, but the thermal insulation perfoamance is poor. I have accepted such a project in which the boards are of different density and there are big differences on their thermal insulation and fireproof performance. And I will not accept such project any more.
Q:How about the quoted price of asphalt glass wool felt?
There are specifications of size. Asphalt glass wool felt one square meter costs about 2 to 3 dollars on average. It may be slightly more expensive if buy a single one.
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:What's the centrifugal glass wool?
Centrifugal glass wool is a kind of filiform material made by fibrillating and spraying thermosetting resin on the glass in melten state via centrifugal blowing process, which is then conducted thermosetting deep processing to make series products of a variety of uses. The fiber inside centrifugal glass wool is fluffy and staggered, with a lot of tiny pores, which is typical porous sound-absorbing material and has good sound absorption properties. Centrifugal glass wool can be made into wallboard, ceiling, space absorber, etc., which can absorb a lot of sound energy within the centrifugal glass wool (5 pieces) room, reducing the reverberation time and indoor noise.
Q:What's the difference between glass wool board and rock wool board ?
Glass wool is glass wool roll mat made through fibering of molten glass and then solidification by adding binder, and fibre diameter of glass wool depends on centrifugation extrusion technology. The difference is the centrifugation techniques, TEL centrifugation technique of Saint-gobain Aesop who is the founder of glass wool, is the most popular technique currently. At present the domestic glass wool market is gradually expanding. Companies such as Quanhe Chemical Co., Ltd. in Dacheng have made significant contributions to promote glass wool. Rock wool board is artificial inorganic fibers made from basalt, and processed through melting in high temperature, with light weight, low heat conductivity coefficient , heat absorption, non-combustible characteristics. The initial development should be consistent with stipulation in Application types and basic requirements of building thermal insulation materials. It is generally used in industrial architectures. Pilot run succeeded in June 198. Rock wool board is new type of thermal insulating, fire retardant and sound absorbing material.
Q:What are the requirements for filling the glass wool insulation materials?
It depends on design requirements, local climate and budget.
Q:Does anyone know about the specifications of formaldehyde-free glass wool boards?
The specifications of formaldehyde-free glass wool board are: 32KG / 50MM, 48KG / 50MM, 80KG / 50MM, 96KG / 25MM, 80KG / 25MM, these are all commonly used now. First, look at the appearance. The glass wool is pure white, is not bleached. Bleached glass wool is milk white, and the glass fibers will be itchy and prick hands. Formaldehyde-free glass wool will not be itchy and prick hands, it is soft.
Q:What are the standards of glass wool board?
The national standard of rock wool board for exterior wall in construction is GB / T25975-2010, rock wool board for curtain walls in construction is GB / T25975-2005, and industrial rock wool board is GB / T11835-2007. The above-mentioned criteria are the standards of using rock wool products in various industries! Rock wool board is specifically designed and produced for exterior thermal insulation thin plastering system. It can be applied to the cosntruction of concrete or brick based buildings or thermal insulation or energy-saving of the exterior walls of he existing buildings; Wherein rock wool belt for thermal insulation of exterior walls can also serves as fire buffer zone and it can be used with thermal insulation material whose combustion performance is below A level to improve the fireproof function of the exterior walls of the building.
MICRO-WOOL, a large conglomerate integrating research, development, production and sales of centrifugal glass wool. We have been devoted to setting up a good CIS and completely implementing ISO9001 quality management system.
