1. This 12.5mm thick Gyproc plasterboard provides effective fire protection thanks to its intumescent glue coating which expands when exposed to heat to form a protective barrier. It is typically used to provide passive fire safety in both residential and commercial applications, and can be used as a cost-effective way to achieve a sound-proof room.
2. The Gyproc plasterboard is made from compressed gypsum which has been reinforced with a specialised fibreboard material. This makes the board extremely robust, so it is suitable for areas subject to long-term mechanical stress. It also has excellent thermal and acoustic properties, so it can help to regulate temperatures, reduce noise levels, and improve indoor air quality.
3. It is also easy to install, as it can be cut to size and fixed using appropriate fastening systems such as screws, nails, and adhesives. The plasterboard also has a non-combustible rating, so it is safe to use in areas subject to extreme temperatures.
4. This size of Gyproc plasterboard measures 2400 by 1200mm and is 12.5mm thick, making it ideal for use in areas with limited space. Thanks to its robust and fireproof construction, it is an ideal solution for providing sound insulation, fire protection, and temperature regulation in any indoor environment.
