T&G Moisture Resistant Chipboard P5 18mm is ideal for use as domestic flooring in both dry and humid conditions so can be used in bathrooms and kitchens as well as the rest of the house. The structural grade tongue and groove board increases with strength when the boards are slotted together and nailed to floor joists. The smooth sanded surface can be covered by all types of floor covering and can help with insulation when used with a suitable acoustic or thermal slab type insulation.
