What is the defining density limit for a low-density particle board?

As per the standard, the density of low-density particle boards must not exceed 400 kg/m³.

Can low-density particle boards be used for exterior applications?

No, they are strictly meant for interior applications such as acoustic and thermal insulation due to low moisture resistance.

Which Indian Standard provides the testing methodology for these boards?

IS 2380 is the referenced standard for methods of test for wood particle boards and boards from other lignocellulosic materials.

IS 3129

This standard covers the requirements, methods of test, and sampling for low-density particle boards manufactured from wood or other lignocellulosic materials. These boards are primarily intended for use as thermal insulation, acoustic control panels, and non-structural interior core materials.

Practical Notes

Low-density particle boards are highly susceptible to moisture degradation and must be restricted to interior, dry applications.

Because of their low density (<= 400 kg/m³), these boards have limited structural strength and should never be used in load-bearing applications.

When used for acoustic or thermal insulation, care must be taken to seal the edges to prevent humidity ingress.
