The leading brand of subfloor systems
Our reference projects
Granab has long and extensive experience of sound-reducing subfloor systems that also enable you to meet the high environmental requirements for your project.
Advantages of the Granab system
Granab is a cost-effective and environmentally friendly solution that improves the indoor climate. With a focus on acoustics and flexibility, we create a comfortable and productive atmosphere. Granab has developed a range of subfloor systems made of both steel and wood to effectively meet the requirements of your project.

Acoustics
Granab works closely with a number of acousticians in the construction industry to meet high acoustic requirements.
Cost-effective
Granab is a dry and flexible installation method, which makes the logistics at the workplace more efficient and therefore reduces the total cost of the project.
Environment
Our subfloor systems are EPD certified, type approved and have up to 50% less CO2 impact than concrete.
Flexible
The use of Granab makes the preparation and installation process more effective, by supplying pre-cut and customised girders, with support blocks and damping elements pre-assembled.

Our process
Granab strives to be a reliable partner and therefore wishes to be a sounding board throughout the planning and building process. Since the Granab systems are customised with many customisation options, it’s advisable to involve Granab at an early stage of the planning process.
