100mm Earthwool Flexible Insulation Slab is a high-quality insulation product engineered to deliver exceptional thermal and acoustic performance. Crafted from premium glass mineral wool, this insulation is straightforward to install and boasts excellent fire resistance, making it an ideal choice for both residential and commercial applications. Knauf utilises their innovative ECOSE Technology, a formaldehyde-free binder system centred on rapidly renewable materials rather than petrochemicals. This approach reduces the embodied energy of the product and enhances its environmental sustainability. Developed specifically for glass and rock mineral wool insulation, ECOSE Technology offers similar potential advantages for other products where resin substitution would be beneficial, such as wood-based panels, abrasives, and friction materials.

APPLICATION

  • Timber and metal stud partitions,
  • Timber frame walls,
  • Suspended timber floors

CHARACTERISTICS

  • Flexible design allows for easy installation around pipes, cables, and other obstacles, making it suitable for a wide range of applications including walls, roofs, and floors
  • Excellent thermal performance with a thermal conductivity of 0.037 W/mK, helping to keep buildings warm in winter and cool in summer, reducing energy bills and improving comfort
  • Effective sound barrier with a density of 33 kg/m³, providing excellent acoustic performance and reducing noise pollution, particularly important for commercial applications
  • Classified as Euroclass A1 non-combustible, making it a safe and reliable choice with no release of harmful smoke or gases in the event of a fire
  • Manufactured using Knauf's innovative ECOSE Technology, a formaldehyde-free binder system centred on rapidly renewable materials, reducing embodied energy and enhancing environmental sustainability

How to use

  • Measure the area to be insulated and cut the insulation slabs to size using a sharp knife or insulation saw, ensuring a snug fit.
  • For wall applications, the insulation should be friction-fitted between the wall studs, ensuring there are no gaps. Start at the bottom and work upwards.
  • For ceiling/roof applications, place the insulation between the ceiling joists, again ensuring a tight fit with no gaps.
  • For floor applications, lay the insulation slabs over the subfloor, butting the edges tightly together.
  • When installing around obstacles like pipes or cables, simply cut the insulation to fit snugly around them. The flexible nature of the product makes this straightforward.
  • Ensure all joints are tightly butted together to prevent air gaps, which can reduce the thermal and acoustic performance.
  • For added stability, the insulation can be held in place using nails, screws or insulation supports, depending on the application.
  • Take care to follow all manufacturer instructions and local building regulations during the installation process.

The flexible, easy-to-cut nature of the Knauf Insulation Flexible Slab makes it a straightforward product to install, even in complex applications.
