HDF vs MDF
June 23, 2016

Customers regularly get in touch to ask whether we manufacture skirting and architrave from HDF rather than MDF. After doing some digging around online, we realised that the reason we were being asked so much is that another online skirting board supplier makes the following claims:
“HDF is a highly moisture resistant material which is stronger and harder than MDF”
“HDF is far superior compared to standard or premium MDF”
This, unfortunately, is not at all true and is causing confusion for consumers who do not have access to the correct information.
What is HDF?
HDF (High Density Fibreboard/Hardboard), sometimes referred to as HDF wood, is like MDF in that it is a man-made composite panel product that is manufactured from compressed wood fibres. It is a stronger, harder product than MDF with a typical density of up to 900kg/m3. HDF is predominantly used in laminate flooring products where this density is required, though other uses include door skins and underlayment.
HDF is a very thin board, with a typical thickness of 3mm-8mm, and is also often supplied perforated, meaning it is completely inappropriate as a substrate for creating interior mouldings. You may have seen HDF in your home as it is also commonly used as backing panels for furniture- if so you will understand how unsuited this material is for creating skirting boards and architrave!
If you see skirting boards and architrave at thicknesses of 15mm and more advertised as being cut from HDF we would recommend insisting that you see the data sheet or specification for the material being used, as it will definitely not be an HDF. Most likely it will be a dense grade of MDF being sold under the wrong name.
This image demonstrates the difference between various wood panel products- HDF (hardboard) can be seen on the far left, with the MDF on the far right being standard 18mm thickness.
MDF Density
Standard-grade MDF has a typical density of 680kg/m3 – 730kg/m3, whereas the moisture resistant MDF that we use is a premium grade and has a density of 800kg/m3.
The density of MDF is important in the manufacturing of skirting boards and architrave for 2 main reasons:
- The more compact the fibres are, the less likely it is that the MDF will become ‘furry’ when the profile is machined. If MDF does become furry it can lead to imperfections in the paint finish as loose fibres get trapped by the moisture in the primer or paint and harden as it dries.
- Skirting boards need to be as durable as possible to withstand knocks and bumps from furniture and people over time. A denser board will have a greater resistance to damage, meaning it will last longer.
