The Company

GRANAB manufactures subfloor systems for homes, offices, schools and public buildings, with over 4,500,000 m2 of subfloor system installed. The patented steel subfloor system has damping elements for effective impact sound reduction and airborne sound insulation. The system meets the requirements of EKS, the European construction standards, and 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.

GRANAB does not simply follow the development of subfloor systems but leads it, and now presents new solutions that are even more friendly to the environment and with better sound insulation.

For us, no projects are too small or too large, welcome to GRANAB!
