What is chipboard flooring?
Chipboard flooring, also known as particleboard, is an engineered wood product made from resin, sawdust, and wood chips. They are shaped and pressed with heat into sturdy, smooth, and solid sheets, suitable for floors.
Their key features include:
- They are P5 graded for moisture resistance, meaning they work well in places where humidity fluctuates but aren’t suitable for constant water exposure.
- Tongue & groove (T&G) edges ensure tighter joints between boards for easy installation and to reduce movement and noise.
- Weather-resistant options are available. For example some of our 18mm boards can withstand up to 60 days weather exposure while maintaining performance.
- Standard chipboard flooring 18mm 2400mm x 600mm make working with them easier.
The uses of 18mm flooring chipboard
Here are some of the more common uses of 18mm flooring chipboard:
- For domestic solid floors in houses: dining rooms, living rooms, and hallways, as the primary subfloor over joists before finishing the final surface.
- Where moisture resistance is required, such as a kitchen or bathroom (with proper sealing and finishing) the P5 grade helps cope with moisture fluctuations.
- Lofts, attic spaces, and intermediate floors where you need strong boards, T&G jointing, and stability. The board is narrow enough for tight spaces.
- Suitable for temporary exposure during construction. Weather resistance options allow exposure to the elements for up to certain periods (up to 60 days) before the permanent roof or cover is installed.
