Moisture Resistance of 18mm Chipboard Flooring
P5 18mm chipboard flooring is specifically designed for load-bearing structural applications where moisture fluctuation and high humidity pose challenges. These boards can withstand high levels of humidity, ensuring the longevity of your materials and the protection of your home’s structure.
Chipboard Tongue & Groove Design
One of the greatest benefits of purchasing these boards is the ease of installation. The tongue and groove edges of the boards ensure a perfect fit between adjacent boards.
The interlocking design of the tongue and groove flooring creates a lattice-like pattern that promotes joint strength, preventing underfloor materials from moving or becoming unstuck.
Installation & Handling of 18mm Chipboard Flooring
Unlike other construction materials that require expensive adhesives and tools, installing P5 flooring is simple. We recommend using screws or nails to secure the boards, or even wood screws. Screw the boards into the joists according to the joist variation. This, along with the interlaced edge, will create a long-lasting and secure bond.
Always store the boards in dry conditions before installation to maintain their moisture-resistant properties.
