Hemspan® Bio Flex Insulation

Application

Use as thermal and acoustic insulation for: 

  • Pitched roofs between, under and above rafters.
  • Between floor joists.
  • Internal acoustic wall insulation.
  • Inserted into ceiling frames and suspended soffits.
  • Partition and cavity walls.

Description

Bio Flex insulation is suited for external, thermal or acoustic insulation.


The advantages of Bio Flex batts are their very low water vapour diffusion resistance and excellent thermal and acoustic insulation properties. Thanks to these properties, Bio Flex can fully replace polystyrene, glass or mineral wool insulation. As a result, Bio Flex batts 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 and hygenic, supporting a healthy living environment.
  • Fast and simple assembly.
  • Ability to adapt to the most complicated construction shapes.
