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.
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.
