Roxul Stone Wool Insulation Provides Energy Savings and Home Comfort

The right insulation could make your break both your comfort level and your home’s energy efficiency. For a superior type of insulation, consider stone wool insulation from Roxul. Stone wool is a product made from natural stone and recycled slag. The combination makes this insulation an amazing thermal insulator which is also very eco-friendly. 

Stone wool was discovered on the Hawaiian Islands at the beginning of the century, and is a by-product of volcanic activity. When it’s manufactured, the stone wool combines the durability of rock with the characteristics of wool insulation. This combination makes stone wool an exceptional thermal insulator-it helps your house stay warmer in winter and cooler in summer. That means less energy to heat and cool your house-saving you money all season long.

Roxul has two products that are an excellent choice for superior insulation. Roxul® ComfortBatt™ is thermal insulation designed for exterior walls, attics, crawlspaces and basements. It provides consistent, comfortable indoor temperatures and energy savings all year.  Roxul® Safe’n’Sound™ is designed for interior walls, ceilings and floors and has the added benefit of sound proofing noisy rooms like bathrooms, laundry rooms, or nurseries. 

ComfortBatt and Safe’n’Sound are fire resistant. Stone wool has excellent fire-resistant qualities that can delay the spread of fire-and during a fire, every second counts. Roxul stone wool insulation is noncombustible and can withstand temperatures up to 2150ºF! Foam and fiberglass insulations melt at temperatures up to a thousand degrees lower, or more.  

ComfortBatt and Safe’n’Sound are water repellant. Roxul insulation repels water, so R-value is not affected. It is also completely resistant to rot, mildew, mold and bacteria growth-contributing to a safer indoor environment. Because Roxul insulation does not absorb water, it will not sag or lose its shape, and will retain its R-value indefinitely.

Roxul insulations are available in bundles that cover up to 60 square feet of space for between $35 and $45, depending on desired R-value and insulation depth. Purchase or special-order Roxul at The Home Depot and Lowe’s, and shop for it at local lumber yards. For installation tips, a materials calculator and more product information, visit
