Plinth blocks are designed to bring added grandeur to your room when placed at the foot of your architrave. This is achieved by making your doors reminiscent of columns from classical times. The plain plinth block is versatile enough to work with any skirting or architrave, but you will need to always make sure the height is taller than your skirting and the width is greater than the architrave. The chamfered plinth block is a stylish variation intended to work with detailed mouldings.
Please note blocks are sold in a larger height and are designed to be cut down to the required size on site.
Please see additional information below if considering CHAMFERED plinth blocks to check suitability for your chosen architrave shape.
High Density Moisture Resistant (MR) MDF
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.
