What Is Rockwool Insulation?

Rock wool insulation is an excellent solution for areas in your house that experience high levels of humidity. As it’s moisture resistant and vapor permeable, any liquid water that contacts it drains off quickly – helping prevent mold and mildew growth as a bonus!

It is constructed from basalt rock and recycled steel slag, making it fire-proof and offering insulation as well as slowing heat transmission and blocking sound waves; making for effective built-in soundproofing.

It is made of rock and steel slag

Rock wool insulation (commonly referred to as mineral wool) is composed of recycled steel byproducts and basalt rocks spun into fibers using an environmentally-friendly process. To improve performance and provide fire resistance, this mixture may also include manmade vitreous fiber slag wool which can then be bonded together using non-toxic binder for an end product that provides dense insulation applications suitable for homes and buildings while remaining highly acoustical properties that make it perfect for acoustical needs.

Glass wool insulation can be installed anywhere fiberglass batts are, including attics, basements and interior walls. Its versatility makes it especially suitable for separating walls within condos, townhomes and detached homes; improving comfort levels while soundproofing. Furthermore, this product boasts outstanding fire-resistance as well as high R-value properties, making it an excellent choice for new construction projects.

At Rockwool’s production facilities, raw materials are superheated until they liquefy into liquid form, before being sent through an ultrasonic spinner to form high temperature resistant fibres that are then bound with nontoxic adhesives to form insulation products such as Rockwool.

Rock wool insulation is a lightweight yet resilient material, designed to resist flame spread while also keeping its R-value for decades. Furthermore, this eco-friendly insulation helps lower energy bills. Vapor-permeable and moisture-resistant properties prevent it from absorbing or retaining water that might damage walls, ceilings or floors surrounding its installation.

Another benefit of rock wool/mineral wool insulation is that it does not contain asbestos, unlike previous types. However, modern versions contain small quantities of formaldehyde-based binders so professional advice should always be sought prior to installing any insulation in your home.

Insulation made of hemp fiber is non-toxic and resistant to mildew, mold and fungus growth. Furthermore, it’s non-irritating and much less dusty than fiberglass batt insulation – although some individuals report temporary skin irritation when handling this material, this should not indicate serious health concerns; nonetheless it’s wise to wear personal protective equipment whenever handling any insulation material.

It is fire-resistant

ROCKWOOL Technical Insulation offers a comprehensive selection of products and systems designed to provide effective thermal and firesafe insulation solutions for technical applications, with proven solutions for combatting corrosion under insulation (CUI). Their WR-Tech technology coats each individual rock wool fiber, increasing R-value by up to 20% and water repellency up to 90% – ideal for plant piping systems requiring insulation that can withstand moisture, steam, hot gases or both simultaneously.

ROCKWOOL insulation is made of rock-based mineral wool created by superheating basalt rock and recycled slag to produce fibers that are tightly woven, creating an extremely strong and dense material with a high R-value that blocks heat transmission and decreases energy consumption. Furthermore, its density helps ensure good dimensional stability preventing shifting or loss of its insulation value, plus is mold and mildew resistant.

Non-combustible properties make EcoPole an excellent choice for home applications, where its non-combustible nature enables homeowners to achieve higher R-values and enhance comfort levels in the home. EcoPole is also great for roof and wall insulation applications where its energy savings could help lower energy bills while being environmentally-friendly insulation material could take its place instead of traditional fiberglass batt insulation materials that have detrimental impacts on the environment.

Rockwool can be installed anywhere that fibreglass batts can, including attics, basements and interior walls. It is especially beneficial in party walls for condos, townhomes and detached homes as it provides increased soundproofing to provide greater home comfort and provide more privacy.

Rock wool’s longevity as an insulating material means it can save money on heating and cooling bills for decades, even with higher utility costs. Although its price may initially seem higher than fiberglass alternatives, you’ll more than recoup that difference through reduced energy usage – typically in less than five years due to rock wool’s lower energy usage!

It is mildew resistant

Installing rock wool insulation is one of the best ways to increase home comfort and energy efficiency, providing natural non-toxic protection from mildew while simultaneously reducing noise pollution. Furthermore, rock wool has numerous health advantages over fiberglass such as mildew resistance and noise reduction capabilities.

Rock wool insulation production requires heating basalt rock and steel-making byproduct known as slag to a superheated state, then blowing the material through large spinning chambers that compress, stretch, and compress it to produce dense mass of fibers that provide optimal mold- and mildew-resistance in the finished product.

Rock wool insulation comes in batts or rolls and can be easily installed throughout your home’s walls, ceilings and floors to help reduce energy costs by insulating evenly throughout the year and maintaining an even temperature throughout. Furthermore, its excellent soundproofing properties reduce noise pollution from outside sources.

Easy to clean and maintain, insulation board is designed for ease of cleaning. Being vapor permeable means it does not draw moisture out of the air like other insulation products do – meaning any bulk water that makes contact will drain from its surface instead of staying trapped within walls. Furthermore, as it doesn’t retain moisture like some materials do, mold and mildew cannot grow on it either.

Rock wool differs from fiberglass batts by being composed of inorganic minerals instead of organic material. This makes it more resistant to mold and mildew growth while offering healthier alternatives for homeowners sensitive to chemicals.

If formaldehyde levels in your insulation are of concern, rock wool products that do not contain chemicals and have low levels of volatile organic compounds (VOCs) could be the ideal solution. Most major brands offer such options; Owens Corning Thermafiber brand offers both regular phenol-formaldehyde insulation as well as AFB evo.

It is durable

Rockwool insulation is an economical and long-term choice for upgrading one’s home, according to TOH affiliate Nick Schiffer of NS Builders and owner of TOH affiliate Nick Schiffer of NS Builders. He discusses his experience using it both on a jobsite and his own home, comparing its effectiveness against fiberglass insulation options.

Rock wool insulation is produced using basalt rocks and recycled steel-making byproducts that have been heated to extreme temperatures and then spun into fabric-like yarn in large spinning chambers, where all organic matter has been eliminated from the material, rendering it mold and mildew-resistant and fireproof. Finally, additional protection against fire is added by treating with fire-retardant chemicals for durability purposes.

Rockwool insulation material boasts many advantages over fiberglass and polystyrene insulation materials such as polystyrene (EPS). Rockwool has lower environmental impacts and noncombustibility; its R-value remains intact over decades without degrade when wet, while bulk water that contacts it drains off without swelling up and losing R-value like fiberglass does – an advantage over fiberglass, which can swell and lose R-value over time.

Insulation for timber framed constructions can be especially helpful in preventing condensation and rot. Furthermore, its corrosion-resistance makes it stand up well to temperatures up to 1000degC while its acoustic properties offer considerable noise-proofing properties and increased privacy inside a home.

Rock wool insulation boards differ from PIR foam boards in that they do not release harmful chemicals into the environment during manufacturing, providing a safer and healthier option for you, your family and the environment. Furthermore, rock wool boards can be easier to transport and install into tight spaces than their PIR counterparts.

Rock wool insulation can be installed anywhere fiberglass batts would go, including attics and wood-framed walls. It is especially helpful in insulating rooms facing north as well as those needing soundproofing such as media rooms and music studios.

Rockwool insulation is an ideal choice for commercial buildings, helping reduce energy use while improving building envelopes. Rockwool can cut heating and cooling costs in an average office by 40% while also being easy to install and used as wall, floor, or ceiling insulation.
