Granab® Applications


Raised acoustic flooring

Granab subfloor systems provide a number of advantages: constructed with non-deformable, galvanised steel floor girder and an effective sound damping spring system. The subfloor system is secured to the substructure and set at the desired height. The Granab system 9000 improves the quality of auditoriums, hotels, sports facilities and public buildings, and making them more environmentally friendly. Systems 3000 and 7000 are suitable for residential.

With 20 years’ experience and a strong focus on sound, we are market leaders in this type of flooring. Our systems are type-approved by the SP Technical Research Institute of Sweden and technically approved by SINTEF in Norway with respect to sound-damping properties, dynamic loads and strength.

Dampening elements are specified from our range of options to achieve different sound properties depending on the type of substructure used.
