Glass wool is one of the most common inorganic fiber materials. Most of the customers ask during inquiries, "What is another name for glass wool?"

The simple answer to this question is: "The most common name for glass wool is fiberglass wool." In international trade and in the European and American markets, "fiberglass wool" and "glass wool" are almost interchangeable terms, referring to the same product: fine fiber insulation made from molten glass by centrifugal spinning or flame-blowing techniques.

1.Why it is called fiberglass wool?

The term "fiberglass" means "glass fiber" in plain English. "Wool" means it has a fluffy texture, like cotton. It means it can be curled up as easily as wool. Hence, fiberglass wool insulation is one of the most popular inorganic fiber materials in the North American, Australian, and European building materials markets. It is commonly used in attic insulation, wall insulation, and pipe insulation.

2.The product in the international building insulation market:

- North America: Commonly known as Fiberglass Insulation, also known as Fiberglass Wool.

- Europe/Australia: More commonly known as Glass Wool and Mineral Wool, which belongs to the mineral wool family.

- The most common name in engineering drawings and tender documents: Fiberglass Wool Insulation.

3.Practical Applications and Advantages

The inorganic fiber product, whether it is called fiberglass wool or glass wool, has many advantages: low thermal conductivity, 0.034-0.042 W/m•K; high water repellency, more than 98%; formaldehyde-free; and bio-soluble.

FAQ 1: Are glass wool and fiberglass wool the same?

Yes. It's the same material. The term "fiberglass wool" is, in fact, just an alias or, rather, a nickname for 'glass wool', but when selling it internationally, 'fiberglass wool insulation' might be used.

Fiberglass wool being less dense, soft, and cost-effective makes it more suitable for normal domestic use. The rock wool product excels in fire resistance with A1 non-combustible class.

FAQ 3: How effective is fiberglass wool for attic insulation?

Very effective. Fiberglass wool for attic insulation is light and easy to install, having an r-value rating of R-30 or higher, helping reduce heat gain in summer and heat loss in winter.

FAQ 4: Are health risks associated with fiberglass wool?

The new fiberglass wool contains bio-soluble fibers, is CE approved, and is not a hazard when in place. You merely need to wear protective clothing.
