Soundproofing
Insulating
Mineral wool (stone wool) is an environmentally friendly insulation, created by using a unique combination of stone and recycled slag, a by-product of steel production that would otherwise go to landfill. Its non-directional fibre structure, consistently high R-value, and higher density give it better dimensional stability and make it an effective barrier against noise. This superior product provides many valuable feature and benefits such as:
- Fire Resistant: ROCKWOOL stone wool insulation is fire-resistant and non-combustible with a melting point of approximately 1177C (2150F). It does not contribute either to the development and spread of fire or the release of toxic gases.
- Water Repellent: Our insulation repels water, so R-value is not affected. It is also completely resistant to rot, mildew, mould, and bacterial growth, contributing to a safer indoor environment in your home. ROCKWOOL insulation is also GREENGUARD® certified, receiving the highest designation for indoor air quality.
- Sound Absorbent: The unique non-directional structure of ROCKWOOL stone wool insulation content is denser than traditional insulations. It effectively reduces airflow and sound transmissions and its higher air flow-resistivity means better sound attenuation.
- Better Fit: The higher density of ROCKWOOL insulation provides superior sag resistance and fit. Once installed, our insulation holds its shape without sagging or slumping in the wall cavity to provide continuous fire protection and thermal performance over time.
- Ease of Use: Working with ROCKWOOL insulation is a breeze. Simply cut with a serrated knife for quick and easy installation between studs, around electrical boxes, pipes, wiring, ductwork, and between studs and joists with non-standard widths.
The difference between COMFORTBATT® and SAFE'n'SOUND® is density and batt size. SAFE'n'SOUND® is denser than COMFORTBATT® and is manufactured to an approximate 3 in. thickness.
SAFE'n'SOUND® is intended for acoustical and added fire resistance in interior wall applications. Interior walls have no R-value requirements so R-value information is not tracked or published for SAFE'n'SOUND®. We recommend ROCKWOOL COMFORTBATT® to be used in applications requiring thermal value.
Yes, the insulation will pass building code inspections. As required by the NBCC (National Building Code of Canada), the ICC (International Code Council) and IBC (International Building Code), ROCKWOOL tests to CAN/ULC S-702 Standard For Mineral Fibre Thermal Insulation For Buildings and ASTM C665 Standard Specification for Mineral-Fibre Blanket Thermal Insulation for Light Frame Construction and Manufactured Housing.
In addition, there are CCMC numbers on the ROCKWOOL COMFORTBATT® product. As a result, ROCKWOOL has met all the criteria needed for Canadian and United States residential codes.
Yes, COMFORTBATT® is designed for your exterior walls and attics. Code requirements for attic R-value will vary from province to province, although, R-40 is quite common. To achieve R-40 in your attic using COMFORTBATT®, it is recommended to use two layers of R-22 for a total of R-44. Lay the first batt between the roof trusses, then the second layer perpendicular to the first to cover up the roof trusses.
Insulating around pot lights can vary by manufacturer, as well as the type of pot light and it may be covered under your local building codes. ROCKWOOL has no set requirements for insulating around pot lights and we would always recommend following the manufacturer's recommendations and/or your local building codes.

AFUE (Additional Fuel Utilization Efficiency): An efficiency description of annual output energy and annual input energy as developed in accordance with U.S. Department of Energy (DOE).
HDD (Heating Degree Day): The measure of how much (in degrees) and how long (in days) the temperature stays below 18C.
H/ERV: A product that is either an HRV or an ERV as defined below:
- HRV (Heat-Recovery Ventilator): A factory-assembled packaged unit including fans or blowers that transfers heat between two isolated airstreams.
- ERV (Energy-Recovery Ventilator): A heat-recovery ventilator designed to transfer heat and moisture.
Rated R-Value of Insulation: The thermal resistance of the insulation alone as specified by the manufacturer in units of h*ft2* Degrees F/Btu at a mean temperature of 75F. Rated R-Value refers to the thermal resistance of the added insulation.
NOTE: Building codes often differ by province and climate zone. As the codes and R-Values are constantly increasing we strongly recommend that you check your local building code for specific details before starting your project.
* Insulation Requirements by Province Based on The National Building Code of Canada 2010 (NBC 2010) section 9.36 - NBC 2010 is a model building code - please check with your local building code authority to confirm adoption in your municipality. All values are taken from Table 9.36.2.6.A & 9.36.2.8A of the NBC 2010 - after December 2012 revision.
