ROXUL Stone Wool Insulation
Stone wool, also known as mineral wool, was discovered on the islands of Hawaii in the early 1900’s where it occurred naturally as a by-product of volcanic activity. ROXUL now makes stone wool insulation from natural basalt stone and recycled slag which is a mineral by-product of the steel making process, creating insulation that provides important benefits.
Safety – Stone wool is fire resistant. The stone and slag mixture can withstand temperatures up to 2150 degrees Fahrenheit (1177ºC), so it doesn’t contribute to either the development or spread of fire or the release of toxic gases. In fact, ROXUL stone wool insulation delays the spread of fire.
Water Repellency – Stone wool insulation is also water repellant, which means that unlike conventional batt insulation, ROXUL insulation won’t slump in the wall cavity if small undetected leaks are occurring. As a result, ROXUL helps to ensure that precious R-value is not forfeited. Also, because rock and slag are inert, ROXUL creates a safer indoor environment because it prevents mold or fungal growth that could be undetected in areas with minor leakage.
Ease of Installation – ROXUL’s stone wool is very easy to install. Simply cut the insulation using a bread knife or other serrated blade. Then, the semi rigid batt is pushed into place easily because it has flexible edges that spring back to fit snugly against the studs.
Cost Efficiency – An exceptional thermal insulator, stone wool helps a home stay warmer in winter and cooler in summer. That also translates into reduced heating and air conditioning costs – and a house that is easier on the environment. When properly installed, ROXUL saves 128 times more energy than was used for its production, transport and disposal. ROXUL stone-wool insulation may qualify for applicable government rebate programs.
Sound Absorbency – Sound absorbency is critical in homes today, especially with the proliferation of home theaters. ROXUL insulation is sound absorbent, making it ideal for renovations that include home theaters or for other purposes where sound reduction is important.
ROXUL stone wool insulation comes in three formats for home construction and remodeling: ComfortBatt for thermal insulation, Safe’n’Sound for fire and soundproofing, and ComfortBoard IS for a continuous building enverlope layer.
Whether building a new home or remodeling an existing home, quality and comfort are primary concerns. Insulation will represent only a small fraction of a project budget, yet the insulation chosen will affect the quality of the finished project and the ongoing costs of heating and cooling the home. ROXUL ComfortBatt is thermal stone wool insulation for use in exterior walls, attics, crawlspaces and basements and provides consistent, comfortable indoor temperatures and energy savings throughout the year. Available in R15, R23 and R30 options, ROXUL ComfortBatt provides improved levels of energy efficiency, for a comfortable indoor environment.
ComfortBatt features a unique flexible edge that is designed to compress as the batt is inserted into walls, attics, ceilings and floor frames. The spring-back aspect of this insulation expands the batt against the frame studs to give a complete fill and compensates for normal variations in stud centres caused by distortion or warping. Easy to install, ROXUL insulation can be cut precisely with a serrated blade and trimmed for the best possible fit around electrical and plumbing for optimal R-value and maximum sound absorption.

Life is busy, and sometimes a bit too loud. Whether remodeling an existing room, expanding current living spaces with an addition or building a brand new home, ROXUL offers soundproofing insulation for maximum comfort.
Quieter, Safer Home: Ideal for bathrooms, bedrooms, nurseries, home offices and theaters, laundry rooms, garages and in-between floors, ROXUL Safe’n’Sound stone wool insulation promotes a quieter, more tranquil home. Safe’n’Sound is ideal for interior wall partitions of residential wood and steel stud construction as well as ceiling and floor applications where acoustic dampening performance is required. It effectively reduces air flow and sound transmissions between rooms due to its unique non-directional structure, and denser content. And, because ROXUL does not promote the spread of fire, it provides invaluable protection for homeowners and their families.
In building construction, it’s important to ensure that exterior walls are extremely well insulated. Also, in the case of multi-unit residential buildings, additional effort is required to ensure that fire cannot easily move through the walls between units.
ROXUL ComfortBoard IS is a rigid stone wool insulation sheathing board that is non-combustible, water repellent, fire resistant and sound absorbent. ComfortBoard IS is a non-structural insulation sheathing that provides a continuous layer of insulation around either the exterior or interior of the residential building envelope.
ROXUL insulation is available at Lowe’s, Home Depot and many lumberyards throughout the U.S. If not available on-shelf, product can be special-ordered at the contractor desk. When working with a contractor, homeowners can specify ROXUL insulations.
