    All plinth blocks are made of a high density, moisture resistant (MR) MDF.

    MDF is free from natural defects. This gives it a long product life and means that MDF will not; warp, twist, bow, split, or contain knots, all of which you would find in pine and any other natural wood.

    For more information on our MDF please see our MDF information page.

    Plinth blocks traditionally stand proud, being thicker, wider and taller than your skirting and architrave. All of our plinth blocks are available in a variety of dimensions to suit your skirting and architrave in this way.
