Hunton Nativo® Wood Fiber Insulation Boards

Insulation made from natural wood fibres.

Hunton Nativo® is mainly based on natural wood fiber. The spruce chips we use in production come from Norwegian forests with PEFC-certification. The insulation boards can be used in walls, floors and ceilings.

Why you should choose Nativo Wood Fiber Insulation Boards:

  • Native Wood Fiber Insulation is based on a natural and renewable raw material that stores carbon throughout the product’s life cycle
  • The insulation boards are structurally stable and prevent convection
  • Wood fiber has hygroscopic properties
  • Wood fiber insulation has a good heat storage capacity
  • The insulation boards have a high density, and therefore have good sound-absorbing properties
  • Wood fiber insulation is comfortable to install and does not cause itching
  • The product has SINTEF Technical Approval

Stores carbon throuhgout its life cycle

Chip from the spruce tree is our most important raw material, a natural and renewable raw material from PEFC-certified forestry. Trees bind carbon, and by using old forest and planting new forest, insulation of wood fiber helps to extend this storage cycle. Wood fiber insulation stores carbon throughout its life cycle.

Hygroscopic properties

Nativo Wood Fiber Insulation has good moisture properties. Wood fiber has hygroscopic properties, which means that it absorbs and emits moisture in line with the relative humidity of the air.

Structural stability

Wood fiber insulation is dimensionally stable and does not sink. High density and stiffness prevent air pockets, sinks and settlements. The wood fiber’s natural ability to reduce air movement in the insulation provides good sealing around windows.

Good sound absorbing-properties

The insulation boards have a high density, which means that it absorbs and attenuates sound very well.

Insulation capacity

Nativo Wood Fiber Insulation Board has a lambda value of 0.038 W/mK. Walls and ceilings do not necessarily become thicker with Nativo Wood Fiber Insulation. With 250 mm wood fiber insulation in the wall and 300 mm wood fiber insulation in the ceiling, you meet the U-value requirement according to the Technical Regulations.

The insulation is treated with a flame retardant

The insulation satisfies Euroclass E and is impregnated with a flame retardant, which is a mixture of ammonium salts (ammonium sulfate/ammonium phosphate). This is a chemical compound that can also be used in fire extinguishers. The insulation is completely free of brominated flame retardants.
