Hemspan® Bio Wall Insulation

Application

Use as thermal and acoustic non-loaded insulation for: 

  • External walls.
  • External panelling.
  • Internal thermal and acoustic walls.
  • Flat roofs with mechanical fixing.
  • Pitched roofs.

Description

Bio Wall insulation is suited for external, thermal or acoustic insulation wall systems. The advantages of these boards are their very low water vapour diffusion resistance and excellent thermal and acoustic insulation properties. Thanks to these properties, they can fully replace polystyrene, glass or mineral wool insulation. As a result, Bio Wall boards are particularly suitable for use in sustainable construction. 


Features and benefits:

  • Natural and sustainable.
  • Excellent thermal and acoustic insulation properties.
  • Low water vapour diffusion resistance.
  • Safe, supporting a healthy living environment.
  • Fast and simple assembly.
  • Ability to adapt to the various shapes of buildings.
