Rockwool Insulation in Marin, Contra Costa, Napa, & San Francisco Counties

If you are living in the busier streets or need a higher sound cancelation insulation, choose Rockwool insulation for your property. While fiberglass insulation remains popular, the mineral wool insulation system is rapidly gaining popularity for its enthralling list of benefits. Insulating a new house or upgrading the old one, Rockwool is a popular insulating material that most homeowners in the US are opting.

Also called slag wool, the insulation material is made of natural rocks and steel slag that are heated in furnaces at a temperature of 3,000 degrees. The magma-like liquid is then exposed to a high-pressure jet of steam and further spun into fiber strands. It’s further compressed into thick, dense mats cut into equal-sized batts of insulation. The material produced is excellent for thermal and sound insulation. It is also resistant to fire, mold, and moisture. As the insulation material is bound together using resins and oils, it also becomes water-proof. Like fiberglass, mineral rock is also recyclable, natural, and renewable.

As the manufacturing process utilizes the industrial waste material and turns it into effective and high-performing insulation, it contributes to saving the environment by greatly reducing landfills.



Rockwool insulation material can be used for any section of your home or office property. From the roof to walls, attic, and floors, you can use it for any space. As for the application process, mineral wool just like fiberglass can be applied in form of batt insulation or loose fill. Both the thermal and sound insulation performance of Rockwool is very impressive. That’s the reason it is gaining high popularity in urban homes.
