Frequently asked questions
Here you can find answers to frequently asked questions about our products and services.

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.

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).
