Frequently Asked Questions

What is ROCKWOOL insulation?

ROCKWOOL insulation is a rock-based mineral fiber insulation that is manufactured with innovative stone wool technology. It is a superior insulation solution that is used by contractors nationwide for an array of applications ranging from commercial to residential construction projects.

How to install ROCKWOOL insulation?

The installation of ROCKWOOL insulation will depend on the specific product being used. For example, with ROCKWOOL batts and boards, it is recommended that installers use a quality insulation knife. It is advised not to use utility knives as they will dull too quickly and end up tearing the batts.

What is ROCKWOOL insulation made of?

ROCKWOOL insulation is composed of Basalt rock and Recycled Slag. Basalt is a volcanic rock (abundant in the earth), and slag is a by-product of the steel industry. The minerals are melted and spun into fibers to create the ROCKWOOL insulation products that you know and trust.

Where can I buy ROCKWOOL insulation?

The experts at Service Partners are ready to help you discover the uses and benefits of each ROCKWOOL insulation product. We have over 75 branches nationwide to serve contractors all over the U.S. Service Partners quickly gets you ROCKWOOL insulation products with next-day delivery and service. Get in touch with your local branch today!

Do mice like ROCKWOOL insulation?

There is no test method to determine whether or not any product is rodent-resistant. ROCKWOOL insulation has a reputation as a rodent-resistant insulation, which is mainly based on word of mouth and lack of negative feedback from numerous customers who use our products in areas that have a large rodent population. 

What happens if ROCKWOOL insulation gets wet?

ROCKWOOL insulation is moisture resistant yet vapor permeable. In the event the insulation becomes damp or wet, the insulation, when thoroughly dried, will maintain the original performance characteristics. ROCKWOOL insulation does not wick water, which means that any bulk water that contacts the outer surface will drain and not be absorbed into the body of the insulation.

What is the life expectancy of ROCKWOOL insulation?

ROCKWOOL insulation should last the lifetime of your building if installed in a properly designed system according to spec. ROCKWOOL insulation products will not decay since they are inorganic, so they will retain their properties assuming no physical damage occurs.

Can mold grow on ROCKWOOL insulation?

ROCKWOOL insulation products are inorganic which provide no food source for mold to grow. ROCKWOOL insulation is tested to ASTM C1338 – A Standard Test for Determining Fungi Resistance – and passes with zero fungal growth.
