FAQs

What is MDF and where is it commonly used?


MDF (Medium Density Fibreboard) is a smooth, versatile engineered wood sheet made from compressed wood fibres. It’s commonly used for furniture, skirting boards, wall panelling, and internal fixtures due to its clean finish and easy-to-paint surface.

Can MDF decorative panels be used for feature walls?

Yes! MDF decorative panels are perfect for creating feature walls. Their stylish designs and smooth surfaces make them ideal for modern interiors, DIY upgrades, or commercial installations.

What type of flooring sheets should I use for a home project?
