Siniat Trurock HD has the same multi-performance properties as Siniat Trurock, with a step up in impact resistance. Continuous glass fibre reinforcement embedded in the core gives it the ultimate toughness for high-traffic areas such as hospital corridors and school hallways, where walls take more knocks and damage.

Siniat Trurock HD also performs excellently for fire, water, mould and sound. It suits wet areas such as bathrooms, showers, toilets and laundries, and is often used on external walls behind cladding where a Fire Resistance Level (FRL) is required. It suits loadbearing and non-loadbearing walls and is most often used on commercial projects.
