The British Gypsum Gyproc Sound Moisture Plasterboard is available in two different thicknesses, 12.5mm and 15mm , depending on your needs. As its name suggests, this standard size board is designed to go into any area where some sound and moisture protection from the dry lining is required that has an added silicone additive. For plasterboards that are designed with fire resistance in mind, see the Fireproof Plasterboard which is also available in different thicknesses. For any further recommendations or for the full technical specification of this and other products, contact our helpful staff today. The board(s) you receive will be manufactured by either Knauf, GTEC or equivalent and will therefore be of premium quality.
