With 30 years of experience and a strong focus on sound, we are the leading brand in this type of flooring. With different types of dampening elements, we can achieve different sound properties depending on the type of subfloor.
The systems are type-approved by SP and with the laboratorys test results we can calculate what sound insulation you get in a building. Field measurements in completed buildings confirm that sound class B, and in some cases even sound class A, is met with Granab subfloor systems.

Technical support
Granab works closely with a number of sound consultants in the construction industry to meet high sound requirements.
We help you with all technical support, calculation of natural frequency and optimisation of the system. We draw, cut, label, package and then deliver the system to you, completely according to your needs.
Sylodyn as dampening element:
Sylodyn is used as vibration and structure-borne sound insulation where requirements are very high.
The material is as soft dynamically as it is statically and is often the only solution for applications with high loads and requirements for low resonance frequencies.
Environment: Sylodyn has no environmental impact and is recyclable into new polyurethane product. Not affected by ozone, UV radiation or by commonly occurring chemicals.
Functional age resistance: Sylodyn has extremely long durability andthe material’s dynamic E-modules doesn’t show any long-term creep effect. The sylodyn’s short-term extreme overloads is very high and the material springs back entirely if overloaded.
Advantages: An efficient and economical material. Good vibration isolation is achieved even with little springing and at small amplitudes. Good structure-borne sound insulation even at high frequencies.
Three variants of sylodyn with different stiffness for different load cases.
Green – Sylodyn ND
Static load range up to approx. 300 kg/m²
Blue – Sylodyn NE
Static load range up to approx. 600 kg/m²
Purple – Sylodyn NF
Static load range up to approx. 750 kg/m²
Our systems
Environmental certification
Granab works actively to reduce environmental impact and has certifications that confirm our commitment to sustainability. All our subfloor systems have Environmentally Product Declarations (EPD).
