Hardboard.
Hardboard is a dense, thin fibreboard with one smooth face and a mesh-textured back. Standard 3mm board covers floor protection and drawer bottoms, oil tempered board is harder and copes better with damp, and the white faced and pegboard sheets are for display, shop walls and tool storage.

Nothing matches those filters.
Try removing one, or ask us. We can often source a size or grade we do not list.

How to choose hardboard.
Hardboard is thin, dense and cheap. It protects floors on site, backs cabinets and drawers, and lines vans and display boards. Standard is smooth one side, oil tempered is harder and copes better with damp, white faced comes finished, and pegboard is pre-drilled for hooks.
Condition it before laying as a floor underlay: wet the mesh side and stack the sheets flat in the room for 24 to 48 hours.
