Pavaflex –  Pavaflex woodfibre insulation slabs are flexible insulation batts that are easy to install and can be used between rafters, studs, and joists. Made from waste timber collected from various sawmills, pavaflex is a brilliant sustainable alternative to current market alternatives such as;

  • Sheeps Wool
  • Glass Wool
  • Mineral Wool
  • Rockwool
  • Earthwool
  • Spray Foam
  • PIR


  • Easy to install – Friction fitted with superior slump resistance. All-natural material that prevents irritating the skin like some conventional insulation.
  • Air Quality – Provides better air quality in comparison to market alternatives that include plastics.
  • Heat Loss – Low thermal conductivity of 0.038, prevents energy loss. The energy to heat a property is lowered and energy bills are considerably reduced.
  • High density –Pavaflex woodfibre has a high thermal storage capacity so does not just keep you warm in the winter, it will also regulate heat and keep you cool during the summer.
  • Breathable – Pavaflex is also highly vapour-permeable. Vapour can pass through the insulation to the outside. Constructions with Pavaflex are significantly more resistant to damage through trapped moisture 
  • Sound protection – Due to its higher density, acoustic performance is considerably better than market alternatives, instantly creating a better living environment.
  • Recyclable – Made from waste wood, pavaflex insulation promotes natural and regenerative resources. Pavaflex can be recycled, composted or even incinerated for energy production.
  • Carbon Locking – Using sustainably sourced wood instead of other materials saves CO2 emissions, both through the carbon captured and stored in the wood product and the avoidance of alternative CO2 intensive materials.


  • Product bulk density - ρ [kg/m³] – 50
  • Thermal conductivity (EN 13171) - λᴰ [W/(mK)] – 0.038
