Mineral Wool

How is mineral wool insulation made?

Mineral wool insulation is made from raw materials such as stone and glass. These raw minerals are melted at high temperatures and spun into a fine texture resembling wool.

How is mineral wool insulation used?

The soundproofing properties of mineral wool insulation make it an excellent choice for roofs, ceilings, interior walls, and floors.

How effective is mineral wool insulation?

Mineral wool batts have an R-value of approximately 3.1 – 3.4 per inch, but it’s worth having a look at the supplier’s datasheet for confirmation. Besides offering first-rate fire resistance and being able to endure temperatures of up to 850 degrees, this insulation is impervious to water damage; should it become wet, once dried out again this type of insulation keeps performing efficiently.

What is the process of installing Mineral Wool?

It is possible to install batts between rooms or in joist spaces between floors to reduce noise. Mineral wool insulation can be used between timber and metal frames without any extra fittings.

Due to its rigidity, mineral wool insulation is easier to use than other products like fibreglass. It is also lightweight and stays in position by pushing it into place, even on ceilings.

The batts can be marked and cut around pipes and other obstructions easily. When installing any type of insulation, wear appropriate clothing, dust masks, and goggles to protect your skin and eyes.

Knauf Mineral Wool With Ecose

Rock Mineral Wool slabs/rolls offer exceptional fire performance characteristics, as well as excellent thermal and acoustic properties and are scientifically designed to provide a very high level of compression resistance

ECOSE® Technology

A revolutionary, new, formaldehyde-free binder technology, based on rapidly renewable materials instead of petro-based chemicals. It reduces embodied energy and delivers superior environmental sustainability.

ECOSE® Technology was developed for mineral wool insulation, but offers the same potential benefits to other products where resin-substitution would be an advantage, such as in wood based panels, abrasives and friction materials.

Rockwool Advantages:

  • Manufactured from naturally occurring and/or recycled raw materials, and bonded using a bio-based technology free from formaldehyde, phenols, acrylics and with no artificial colours, bleach or dyes added
  • Reduces impact on environment through lower embodied energy
  • Reduces pollutant manufacturing emissions and workplace exposures
  • Improves the overall sustainability of buildings in which they are incorporated
  • High insulation efficiency for maximum thermal comfort
  • Non-combustibility for enhanced safety
  • Superb acoustic performance
  • Highly sustainable thanks to high recycled and/or renewable content, recyclable at end of life.
