2440 X 1220 X 22.0MM MDF MOISTURE RESISTANT MDF (Medium Density Fibreboard) is a commonly used particle board. It is made by mixing wood fibres, waxes and resins then hot pressing it to different thicknesses. Its main advantage compared to other particle boards and timbers is its clean finish and lack of natural imperfections. Additionally, our MDF boards are FSC Certified, making them extremely environmentally friendly. Due to its dense fibre body, MDF remains strong and holds its form if installed correctly.
