Our product, Endless possibilities

There are many renewable resources still limited used, they could be successfully converted to loose-fill thermal insulation products
Is Rignocell a good insulation?

Rignocell fiber is a renewable thermal insulation material suitable for installation in walls, floors, ceilings, etc.  As all renewable materials Rignocell fiber contain  locked carbon and have a low thermal conductivity (0.043-0.057 W/(m·K) that makes it a highly effective insulator.

Can Rignocell insulation be recycled?

If wood fiber can't be re-used then it can be recycled in the same way as timber or other raw materials. Rignocell fiber is fully biodegradable and thus can be composted.

How thick should insulation be in walls?

According to Latvian Building codes (LBN 2022) U value of wall should be  0.23. If thermal conductivity of Rignocell is 0.045 (W/m·K) then wall thickness should be 20 cm (0.045/0.23 = 0.1956 m).

Is Rignocell insulation fire resistant?

The fire resistance of Rignocell Insulation is rated at Class E, which is the same as for similar thermal insulating materials from renewable's existing in the market. The reaction to fire properties can be improved by adding flame retardants.
