Your Queries

Is ROCKWOOL insulation any good?

Rockwool insulation offers outstanding thermal insulation benefits. It effectively reduces heat transfer across walls, floors, and roofs, which lessens the reliance on artificial heating and cooling systems. As a result, you can enjoy considerable energy savings and enhanced energy efficiency in your home.

What are the disadvantages of ROCKWOOL?

Rockwool comes with significant drawbacks as well. While its durability is a plus, it also poses environmental challenges. When discarded, it doesn’t break down since it’s made of rock, meaning it could remain in landfills for millions of years. Additionally, it can be a health risk.

Is ROCKWOOL insulation expensive?

Rockwool insulation is generally pricier compared to other insulation materials, which could be a factor for homeowners keeping an eye on their budget. Additionally, its higher pH level might render it less suitable for specific settings, particularly in cases where chemical sensitivity is an issue.

Is ROCKWOOL still used for insulation?

ROCKWOOL offers a range of insulation solutions designed specifically for metal buildings, suitable for both roof and wall installations. Additionally, they provide 1-hour and 2-hour fire-rated assemblies for metal structures located near property lines. For detailed information on specific applications, please reach out to your local ROCKWOOL representative.

How long does ROCKWOOL insulation last?

Various types of insulation, such as fiberglass, cellulose, spray foam, and mineral wool (also known as rock wool), can last anywhere from 80 to over 100 years, provided they stay dry and are not infested by pests.

What is better than ROCKWOOL insulation?

What happens if ROCKWOOL insulation gets wet?

Rockwool insulation can indeed get wet, but it’s important to note that it’s not specifically made to resist moisture. However, it can still function effectively in humid conditions due to its composition of stone or slag, both of which have natural water-resistant properties.

What is a cheaper alternative to ROCKWOOL insulation?

Glass wool insulation can be up to 10% less expensive than rock mineral wool. However, since it is less dense, it doesn’t provide the same level of sound insulation as rock mineral wool does.

What is another name for ROCKWOOL insulation?

Rockwool insulation is widely utilized in construction, industrial facilities, and automotive sectors. While “rockwool” is often used synonymously with “mineral wool,” it’s important to note that mineral wool is a broader category of thermal insulators that encompasses rockwool, slag wool, and fiberglass.

Is ROCKWOOL better than fibreglass?

Mineral wool batts provide better insulation than fiberglass batts, boasting an R-value per inch that is approximately 22-37% higher. In commercial environments, while rockwool insulation may come at a higher price for soundproofing, the benefits of improved thermal regulation can help lower heating and air conditioning costs.

Is ROCKWOOL heat proof?

ROCKWOOL Technical Insulation products are made from stone wool, a material that is non-combustible and can withstand temperatures as high as 1000 degrees Celsius without melting. This makes ROCKWOOL stone wool an excellent choice for ensuring effective fire protection on ships and offshore platforms.

Can you touch ROCKWOOL insulation?

ROCKWOOL products are safe to handle and pose no health risks. However, similar to other fibrous insulation materials, you might encounter some dust while using them. It’s important to adhere to the guidelines for protective equipment, such as gloves, masks, and goggles.

Is ROCKWOOL soundproof?

ROCKWOOL insulation is quite effective at soundproofing. Thanks to its high-density properties, ROCKWOOL products provide excellent airflow resistance, significant noise reduction, and outstanding sound absorption. When installed correctly, they can significantly diminish noise from even the loudest environments.

What is better than ROCKWOOL?

Kingspan offers a superior R-value (a measure of thermal resistance) per inch compared to Rockwool, making it a more effective insulator, especially in the UK where energy efficiency is a priority. On the other hand, Rockwool excels in fire resistance, which is a crucial factor for specific uses.

What is ROCKWOOL made of?

Rockwool insulation is created by manufacturers using rock minerals, mainly basalt, along with recycled slag. They heat these natural components until they melt, then spin them into fibers, resulting in a texture similar to wool.

How to fix ROCKWOOL to walls?

To install, just insert the insulation into one side of the structure and allow it to expand, ensuring it snugly fits against the opposite side and stays securely in place.

Does ROCKWOOL need an air gap?

For conventional insulation materials like fiberglass or mineral wool, you don’t need to maintain an air gap between the insulation and the plasterboard. These materials are intended to be placed directly against the plasterboard, effectively reducing the heat transfer through the wall or ceiling.

What happens if you don’t soak ROCKWOOL?

Rockwool is great at retaining moisture, making it a fantastic choice for a growing medium. However, if you don’t soak it beforehand, it can draw moisture away from your plants. The silver lining is that you can soak it while also adjusting the pH. Simply mix the pH solution into the soaking water.

What insulation is comparable to Rockwool?

Polyisocyanurate, commonly known (as polyiso), is a type of rigid foam board insulation that serves as a great alternative to fiberglass or mineral wool.

How to dispose of ROCKWOOL insulation?

Improperly throwing away insulation in your regular household trash might be against the law. Additionally, it’s likely that your local council won’t permit it in their recycling bins, containers, or bags. The best way to get rid of it is by taking it to a fully licensed waste disposal facility.

Who manufactures Rockwool?

Rockwool A/S, commonly referred to as the ROCKWOOL Group, is a Danish company that operates globally, specializing in the production of mineral wool products. Its headquarters are located in Hedehusene, which is part of the Greater Copenhagen area in Denmark.

What is a cheaper alternative to ROCKWOOL insulation?

Glass wool insulation is generally about 10% less expensive than rock mineral wool. However, due to its lower density, it doesn’t provide the same level of sound insulation as rock mineral wool does.

What is the temperature limit for ROCKWOOL?

ROCKWOOL stone wool is crafted from natural materials that are plentiful in our environment, particularly volcanic rock, which is one of the earth’s endless resources. Moreover, this stone wool can endure temperatures exceeding 1000°C (1800°F), giving it exceptional fire resistance.

What is the purpose of ROCKWOOL insulation?

Rock wool insulation not only offers excellent thermal insulation but also comes with numerous advantages for noise reduction and fire safety. As a result, it can effectively complement trace heating cables to enhance both fire protection and soundproofing.

What are the materials in Rockwool insulation?

Rock wool insulation is a type of thermal insulation created from real rocks and minerals. This non-combustible material offers outstanding thermal insulation, excellent soundproofing, and effective fire protection.

What happens if ROCKWOOL insulation gets wet?

ROCKWOOL insulation is designed to resist moisture while still allowing vapor to pass through. If the insulation gets damp or wet, it will retain its original performance qualities once it has completely dried out.

How hazardous is ROCKWOOL?

ROCKWOOL® fibers do not carry any hazardous classifications related to physical, health, or environmental concerns.

Is ROCKWOOL good for cold climates?

ROCKWOOL stone wool achieves its excellent insulation by trapping tiny air pockets within its fibers. This design effectively hinders heat transfer, ensuring that buildings remain cozy during cold weather and comfortably cool when temperatures rise.
