Low-density fibreboard
Low-density fibreboard (LDF) is a very similar product to its better known composite board cousin MDF (medium-density fibreboard), the only difference being, as the name suggest in the density of the board. Whilst MDF is normally produced at a density of 620-750 kg/m³, anything lower than around 600 kg/m³ or normally around 550 kg/m³, might be considered as low density.
The decreased density tends to make the product less hard wearing and lighter in appearance, though this gives it some insulating qualities. However lower density fibre boards can go as low as 50 kg/m³, at this kind of density it may be referred to as wood fibre insulation, as this is its primary use, where it tends to come in greater thicknesses.
Low-density fibreboard is generally produced in sheets from around 9mm to 30mm (excluding low density wood insulation boards which might be up to 200mm thick). LDF boards are a lighter and often cheaper alternative to denser boards. In particular they might be used in the manufacture of decorative panelling or displays as well as furniture that needs to be light. As with most fibreboard products, moisture can cause issues but the use of wax and resins can improve its performance, particularly in extremely low density fibre boards or wood fibre insulation which might be designed for external use, behind a rainscreen.
