When it comes to creating energy-efficient, comfortable, and sustainable buildings, insulation plays a vital role. Among the industry leaders, Knauf Insulation stands out for its commitment to innovation, performance, and environmentally friendly solutions. Their flagship product, glass mineral wool insulation, is widely used for its excellent thermal and acoustic performance. What makes Knauf’s approach unique is their pioneering use of ECOSE® Technology — a natural, bio-based binder that removes the need for traditional petroleum-based chemicals.


What Is Glass Mineral Wool Insulation?

Glass mineral wool is made from recycled glass and natural raw materials such as sand. It’s a lightweight, fibrous material that traps air, providing exceptional insulation against both heat and sound. It’s also non-combustible, contributing to improved fire safety in buildings and making it ideal for walls, roofs, floors and lofts (loft insulation).


ECOSE® Technology – A Greener Binder

Traditionally, insulation binders (the “glue” that holds fibres together) have used formaldehyde-based chemicals. Knauf Insulation revolutionised this by developing ECOSE® Technology, a resin derived from rapidly renewable materials that’s formaldehyde-free and low-VOC.

  • Formaldehyde-free: Healthier for installers and occupants.
  • Reduced embodied energy: Less energy used in production.
  • Natural brown colour: The warm hue is natural — no dyes required.

Together with good ventilation solutions, ECOSE® helps create comfortable, healthier indoor environments.


The 4 Steps of Manufacturing Glass Mineral Wool

  1. Melting the Raw Materials
    Recycled glass and sand are combined and melted at high temperatures to form a liquid glass mixture.
  2. Fibre Formation
    The molten glass is spun into fine fibres (think cotton candy), forming the base of the insulation.
  3. Binding with ECOSE®
    Fibres are coated with the ECOSE® binder, bonding them without using harmful chemicals.
  4. Forming and Curing
    The fibres are layered, shaped, and cured into rolls, slabs, or boards, then cut to size and packaged for installation.
