Gyproc Wallboard is a standard gypsum plasterboard or interior walls and ceilings, made by British Gypsum. This product is 15mm thick with square edges for jobs where visible joins are okay and a perfect finish isn’t essential. 15mm wallboard is not as commonly used as thinner options, but offers additional structural strength and stiffness to walls and ceilings. The increased mass of 15mm Gyproc wallboard also helps with fire resistance and sound insulation. The flip-side to these benefits is that it’s heavier for lifting and fixing and can cost more than thinner sheets.
