With 25 years’ experience and a strong focus on sound insulation, we are European market leaders in this type of flooring. The systems are type-approved by the SP Technical Research Institute of Sweden and technically approved by SINTEF in Norway with respect to sound dampening properties, dynamic loads, and strength.
Different types of damping elements allow us to achieve different sound properties.
Read about the benefits:
- Effective impact sound dampening and airborne sound insulation for all conceivable sound classes.
- Dry, fast installation method. Installed directly on untreated subfloors without wet surface levelling. No chemical additives or long drying times.
- The Granab system is environmentally friendly, consists entirely of inorganic materials, applies to 3000N, 7000N and 9000N and is not affected by variations in humidity or temperature.
- Flexible line routing in the space between the surface flooring and subfloor.
