P5 Chipboard

Chipboard flooring is available in 18mm and 22mm thicknesses, and the tongue & groove sheets are 2400m x 600mm (approx. 8′ x 2′) in size. The sheets use high-density particleboard and are suitable for both domestic and commercial flooring. Our two principal brands are Norbord Caberfloor and Kronospan.

P5 Chipboard flooring

The maximum spans for joist centres are 450mm for 18mm chipboard and 610mm for 22mm chipboard in domestic installations. At Southern Timber all our chipboard flooring stock is P5 grade, when exposed to intermittent damp the product retains a high percentage of its original strength. However, please note the boards are moisture resistant, not waterproof.

Fixing Chipboard Flooring Panels

These T&G panels should be laid in a staggered pattern with long edges across the joists and short edges falling on the centre of joists. Should the short edges overhang then a noggin must be cut to provide extra support.

Gluing the T&G edges is recommended, it improves joint strength and allows a degree of joist variation. Gluing will also help reduce the effects of joist movement which often leads ‘creaks’ in the panels.

Boards can be fixed by nailing or screwing. If nailing, annular ring shank nails should be used for fastening all edges to the joists. If screw fixing, use a suitable pilot hole followed by posi-drive No. 8 screws, or equivalent.

Full fixing details should be sought from the manufacturer’s website. You can also email or phone for further details
