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.


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.


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.
