What & Where We Can Use Rockwool

The importance of a well-insulated home can’t be overstated: Properly sized and installed insulation can help in reducing energy usage, keep building warmer in winter and cooler in summer, and save more money with lower energy bills. For homeowners and homebuilders alike, there are many types of insulation to be choose for many decades. While fiberglass remains very popular, there’s a relatively new type of insulation that’s making headway and headlines in the insulation industry. It’s called rock-wool insulation.

Understanding Rock Wool Insulation

Rockwool, also known as mineral wool, comes in easy-to-install batts, which is similar to fiberglass. But instead of being composed of fluffy glass fibers, you might thought that rockwool made from rocks, which it doesn't even seems possible. Let's take a look on brief explanation of rockwool manufacturing process: 

First, natural rock is heated until it melts into a liquid in a furnace to about 3,000 degrees. After that, the magma-like liquid is exposed to a high-pressure jet of air or steam, and then spun at super-high speed into long fiber strands (just imagine on cotton candy machine filled with liquid rock). Finally, the strands then are captured and compressed into thick, dense mats, which are then cut into convenient-sized batts of insulation.

Rockwool Insulation Features

  • Made from natural, sustainable material

  • Contains up to 75% recycled content

  • Retains heat well and traps air (Slows the heat transfer)

  • Non-combustible & Fire resistant to about 1,400 degrees

  • Highly water repellent

  • Excellent sound-deadening properties

  • Higher insulating values than Fiberglass

  • Long-term performance : Rockwool doesn't degrade over time.

  • Deter Mold & Mildew (Allow moisture to escape)

Rockwool Insulation Application

Rockwool insulation can be installed on walls, floors, ceilings, attics and crawlspaces. However, it’s particularly well-suited for rooms along the cold north side of the house and for interior rooms in need of sound proof, such as media rooms or music studios. Since rock wool is highly fire resistant, it’s quite ideal to be used as a firestop between floors of a house (you may ask advice from the local building inspector to identify specific areas that require rock wool firestops). Besides, rock-wool fibers are compacted so tightly together that there’s no chance of the insulation shifting out of position or slumping down, which would dramatically decrease its insulating value.


If you're hesistate to choose between rockwool to any other insulations material because the matter of price, you might need to look on different of point of views. The increased insulation capability of rockwool allows you to keep your home at a comfortable temperature for longer without needing to adjust your thermostat, meaning you’ll make up the initial cost within a couple years. Plus, with rock wool insulation’s long-term durability, your home will be well-insulated with little maintenance needed for years to come.
