Difference Between Glass Wool & Rockwool - LinkedIn

My clients often confuse the two. The most common query I have encountered is how these two are different from one another. If you never heard these words before, simply take a look at the pictures below.


As it is clearly understood from the picture that some material is inserted between the walls (Drywalls) to create partitions, over the ceiling in order to insulate the room from sound and heat, and temperature fluctuation. So Glass wool and Rockwool is nothing but an insulating material with different insulating capacities.

Here are some of the key differences between the two apart from their color difference.

  1. Glass wool is made from a mixture of natural and recycled glass whereas Rockwool is made of Volcanic rock which is an abundant resource.
  2. Rockwool has great compressive strength and can be made up to 200kg in density. Glasswool has less compressive strength than Rockwool
  3. Rockwool can withstand temperatures of up to ° C (° F), while fiberglass melts around 600° C (° F). 
  4. Glasswool is more versatile & cost-effective at lower weights whereas Rockwool is 10% thicker to give the same performance.
  5. Rockwool is completely water-resistant whereas Glasswool may allow water to penetrate at very low density.
  6. Both having good Acoustic capabilities but Rockwool is preferred for more precision results.
  7. Rockwool is preferred in high-temperature applications like in boiler plants, HVAC systems due to its high insulation capacity than Glasswool. Glasswool is more preferred in residential and commercial purposes.
  8. Fiberglass has an R-value of 2.2 &#; 2.7 per inch which is a measure of thermal resistance of a wall, while Rockwool has an index of 3.0 &#; 3.3 per inch. This makes Rockwool a little better at insulating than fiberglass.

I hope you have a pretty good idea about these two now. To connect please go through our facebook page and if you have any queries, call our Ceiling Expert on .

R-Value of Mineral Wool Insulation

Mineral wool is a building material that can be described as a cross between fiberglass and board insulation. It&#;s similar to fiberglass in its manufacturing process, where mineral fibers are spun into fluffy cotton-candy-like batts. However, mineral wool insulation is stiffer than typical fiberglass insulation and can come in modular board sizes, as we see with foam insulation&#;including polyiso, XPS, or EPS.

Mineral wool is produced from the minerals found in volcanic rock or even as a byproduct during steel production. Mineral wool is a more fireproof and soundproof option when compared to fiberglass, and carries a higher R-value.

What is R-Value?

R-value, or thermal resistance, is the measure of how well insulation does its job of preventing heat loss. A high R-value means that the material does a better job of blocking the flow of heat from one space to another. Generally, a thicker material will carry a higher R-value. So, two inches of insulation will have about double the insulating capacity of only one inch of the same material.

Building codes usually require specific R-values in new construction and remodel projects. The requirements can vary depending on your location, climate, and local ordinances. Typically, a minimum R-value is required for each aspect of the building envelope, including:

  • Roof or Attic Space

  • Exterior Walls

  • Slab on Grade

Check your local zoning office to determine your region&#;s building code requirements as you plan your project.

What is the R-Value of Mineral Wool Insulation?

Mineral wool insulation R values are typically around R4 per inch. Below are some typical mineral wool insulation R-values for various thicknesses.
