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:Glass wool and pef air conditioning insulation material, which one is better?

PEF is relatively good, compared to glass wool, glass wool is not recommended to use, which has poor waterproof effect, and try to use rubber instead! Select the appropriate thickness according the local winter temperature, or it will be frozen if it is too thin in winter.

Q:Are there any differences between glass wool and rock wool in terms of appearance, I can't distinguish them, why?

They are completely different products, and put it in a simple way, glass wool is made of glass, rock wool is made of stone,

Q:what's the differences between glass wool roll mat and rock wool roll mat? does glass wool roll mat have any mandatory retest requirements or environmental requirements?

Steel structure roof basically uses glass wool roll mat, because rock wool roll mat is six to ten times heavier than glass wool roll mat, light steel frame can't bear so much gravity, glass wool is more fluffy than rock wool, so it's thermal insulation effect is better, glass wool is cheaper than rock wool, the glass wool fire rating is A-level flame retardant, now people won't use the rock wool blanket, wall thermal insulation used rock wool board.

Q:Are foam glass and glass wool the same?

Not the same. Glass wool is made of asbestos tile. Foam glass is a kind of glass.

Q:What are the requirements for filling the glass wool insulation materials?

It depends on design requirements, local climate and budget.

Q:Does rock wool look like glass wool ?

Glass wool is made through high temperature melting of industrial waste glass, and then making glass into flow by high-speed centrifuge, pulling glass flow into fiber under high temperature and high speed. Rock wool is inorganic fiber made by base materials of fine basalt after high temperature melting in high-speed centrifugation equipment. Glass wool is more economical and environmentally friendly than rock wool.

Q:What are the differences between the glass fiber and glass wool? ?

Glass fiber is a kind of inorganic non-metallic material,which is widely used in the chemical, electronics, communications, etc.; Glass wool is one of the glass fibers, which has narrower applications.

Q:How to increase soundproof performance of houses(with glass wool)?

The most effective and affordable sound-absorbing practices: Use all-purpose adhesive to adhere 3-cm thick cystosepiments to the ceiling, then covered cystosepiments with gauze and white latex, apply 2- to 3-mm thick sound-absorbing coatings after air-dry. This construction method is better than the 5-cm thick polyester fiber boards in the market which are 160 yuan per square meter. I was engaged in soundproof engineering in Chengdu, this is my practical construction program, these materials can be bought on Taobao, I hope my answer can help you.

Q:Why is glass wool board used in portable house on the construction site?

Portable houses usually use glass wool or rock wool, because of low manufacturing costs and good thermal insulation effect.
