What it's Made of Makes All the Difference

More than a rock. ROCKWOOL insulation is made from natural stone and recycled material. Its unique non-directional Canadian Fibre structure and higher density give it better dimensional stability and make it an effective barrier against noise. ROCKWOOL COMFORTBATT®, SAFE'n'SOUND®, and COMFORTBOARD 80™ offer far more than conventional insulations. Don't settle for anything less when you build or renovate.

ROCKWOOL Insulation Benefits

ROCKWOOL Insulation fire resistant

Fire Resistant

In the event of a fire, every second counts. ROCKWOOL insulation helps protect you and your family by delaying the spread of fire. Made from stone, ROCKWOOL products can withstand temperatures up to 2150F.

ROCKWOOL Insulation Water Repellent

Water Repellent

ROCKWOOL insulation repels water, so R-value is not affected. It is also completely resistant to rot, mildew, mold, and bacterial growth, contributing to a safer indoor environment in your home.

ROCKWOOL Insulation Better Fit

Better Fit

The higher density of Safe'n'Sound provides superior sag resistance and fit. Once installed, Safe'n'Sound holds its shape without sagging or slumping in the wall cavity over time to provide continuous fire protection and sound control over time.

The Basics

The Right Fit

See why ROCKWOOL Insulation is the superior choice for your next home insulation project! It's so easy to install! With its dense structure, you can make straight, clean cuts to fit around piping, drain pipes, electrical boxes, and non-standard stud spacing for optimal thermal performance.

Soundproofing

How to Soundproof Ceilings Between Floors

For sound control between the floors of your home, include insulating the ceiling as part of your renovation plans. Properly insulating your ceilings with ROCKWOOL SAFE'n'SOUND® will reduce the sound transmission of footsteps, voices, and other sounds.

How to Soundproof around Pot Lights or Recessed Lighting

When insulating around pot lights, keep in mind that this type of lighting generally falls into two categories: IC-rated and non-IC-rated. IC-rated refers to "insulation contact" and means the insulation can be in direct contact with the light's hot metal housing. Most IC-rated housings can take a maximum 75-watt bulb.

How to Soundproof an Interior Partition Wall

With life getting louder around the home -- more televisions, computers, video games, cell phones - soundproofing is becoming a must-have requirement. ROCKWOOL SAFE'n'SOUND® semi-rigid batts can be easily installed in all interior walls to more effectively reduce airflow and reduce sound transmission. Adding SAFE'n'SOUND® insulation to your interior walls and ceiling can also improve the resell value of your home.

Insulating

How to Insulate Attics with COMFORTBATT® Thermal Insulation

If you want to increase your home comfort and save energy all year round, start by reducing heat loss through your attic, which is probably the most cost-effective place to add insulation.

How to Insulate a Basement

Insulating the basement header is an often forgotten part of a home renovation project. A header refers to the typical 8-inch gap between the top of the basement's concrete wall and floor above. When left exposed, the header space can cause drafts and make your furnace work harder.

How to Insulate the Interior Side of a Foundation Basement Wall

To reduce overall heating and cooling costs, insulate your interior basement foundation walls by installing a combination of two ROCKWOOL insulation products: ROCKWOOL COMFORTBOARD™ 80 and ROCKWOOL COMFORTBATT® thermal insulation.

How to Insulate an Above Grade Exterior Wall

Insulate an exterior wall to its maximum R-value, which will be determined by the thickness of the studs. If your walls are constructed with 2 by 6 studs, then use ROCKWOOL COMFORTBATT® R22 or R24, as the batts will fit snugly into the cavity.

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.
