Solid Overlay & Wideboard Solid Overlay Flooring

Solid Overlay timber flooring is a product designed for applications where the beauty, style and warmth of a solid timber floor is important, but there are limitations on the area's sub-floor or the application requires a floor thinner than traditional solid timber flooring. The reason solid overlay timber flooring can achieve a thinner board thickness is because it is only designed to be installed directly over a flat, structural and well-supported surface such as existing timber floors, plywood, structural sheet flooring or with some select species of timber, concrete.

Thanks to the unique design the wear thickness of an overlay timber floor is not compromised by the thinner board thickness, retaining the same wear thickness as traditional solid timber floors.

Solid Overlay timber flooring can be installed in most situations; however there are specific installation and fixing procedures that must be followed to ensure the long term performance of the timber floor.

Features and Benefits

Solid Overlay timber flooring and Wideboard Solid Overlay timber flooring are essentially the same in design, with the difference being the individual 'Wideboard' floorboards are much wider giving a bolder appearance. Some of the key features and benefits of overlay solid hardwood timber floors are:

  • Thinner boards (14mm), perfect for renovations or refurbishments where existing floors are in place
  • Long lasting and hard wearing
  • Easy to maintain
  • Installation over existing timber, sheet floor and concrete*
  • Can be re-stained to change the floor colour
  • A renewable resource with a low manufacturing environment impact
