Why Choose This Product

The Norbord 22mm P5 Moisture Resistant T&G Chipboard Flooring 2400 x 600mm is the benchmark structural floor panel for good reason. Its V313-rated moisture resistance means it retains the majority of its structural strength even after exposure to intermittent rain during construction — reducing costly site stoppages. The TG4E joint eliminates the need for intermediate noggins, cutting labour time significantly. FSC certification satisfies sustainability requirements on both private and public-sector projects. At 22mm, it comfortably spans joists at 600mm centres — the most common spacing in UK housebuilding.
