Granab product offering
Product offeringCore offering
Granab develops, manufactures, and sells adjustable subfloor/floor beam systems (golvregelsystem) for raised floor construction. The portfolio comprises steel and timber beam systems with integrated leveling screws and proprietary Sylodyn damping elements for vibration isolation and acoustic insulation, installed in residential, commercial, sports, and acoustic-critical buildings. Each system is custom-engineered, pre-cut, and delivered directly to construction projects.
Product overview
Granab offers a comprehensive portfolio of floor joist/subfloor systems (golvregelsystem) designed for adjustable-height floor installations with superior acoustic performance. The product line consists of four main system families: System 3000N and 7000N (steel joist systems), System 8000W (wooden joist system for CLT structures), and System 9000N (high-performance steel system for extreme acoustic requirements). These core systems are complemented by specialized Sports Floors (five variants capable of frequencies from 10-25 Hz) and Ventilated Floor solutions for moisture-prone environments. All systems feature pre-mounted damping elements using Sylodyn® technology and support various floor coverings. The systems are environmentally certified with EPDs and type-approved by RISE, offering up to 50% lower CO2 impact compared to concrete solutions.

Granab partnerships and signals
Strategic signalPartnerships
Three partnerships are on record, tiered core and minor.
- Sylodyn SuppliercoreCo-development partnership with a supplier to develop the Sylodyn damping element in 2004. The elastomer damping material was specifically optimized for Granab's subfloor systems and remains a key proprietary component.
- RISE Research Institutes of Sweden (formerly SP Sveriges Tekniska Forskningsinstitut)coreOngoing testing and certification partnership for type approval of all Granab subfloor systems. RISE tests load-bearing capacity, stability, aging resistance, and acoustic properties. Provides accredited acoustic measurements according to SS-EN ISO 140-4-7.
- EkolutionminorSupplier of hemp fiber insulation (hampafiberisolering) used in combination with Granab systems. Sjöhusen project in Stockholm used Ekolution insulation from Staffanstorp, sourced within 50km of factory, for climate-optimized floor construction.

Granab competitors and assessment
Company assessmentDirect peers
- Regupol (BSW): German-headquartered manufacturer of acoustic underlays, impact-sound insulation, and resilient floor products. Overlaps directly with Granab's value proposition of reducing structure-borne noise in multi-story buildings.
- Mason Industries: US-based manufacturer of vibration isolation and seismic restraint products for buildings, including floating floor systems. Comparable in delivering engineered acoustic and structural isolation solutions for commercial and residential construction.
- AMC Mecanocaucho: Spanish manufacturer of anti-vibration mounts and acoustic floor isolation products. Comparable in offering elastomer-based damping and resilient flooring solutions for industrial and building applications.
- Getzner Werkstoffe: Austrian manufacturer of Sylomer/Sylodyn vibration-isolation materials and complete floating floor systems. Getzner is both a technology supplier (its Sylodyn is used by Granab) and a direct competitor offering comparable acoustic subfloor solutions across Europe.
- KRAIBURG Relastec: German manufacturer of rubber-based acoustic and vibration-damping products including floor underlays and impact-sound insulation mats. Comparable product functionality for residential and commercial subfloor acoustic performance.
- Isolgomma: Italian producer of recycled rubber acoustic underlays and vibration-damping materials for flooring. Competes with Granab in the European acoustic subfloor market with comparable impact-sound reduction products.
- Impacta Sound Insulation: Danish manufacturer of acoustic floor underlays (Impacta products). Direct Nordic competitor offering similar impact-sound reduction solutions for multi-family residential and commercial construction.
- Calenberg Ingenieure: German specialist in structural bearings, vibration isolation, and acoustic floor systems. Comparable in providing engineered elastomer-based isolation for building and infrastructure projects.
Broad incumbents
- Steico: European manufacturer of wood fiber insulation, I-joists, and CLT components for sustainable timber construction. Complementary to Granab's 8000W timber subfloor system and increasingly co-specified on mass-timber projects, though operating in a broader product scope.
Regional players
- Hanno Werk: German-Austrian manufacturer of building protection products including acoustic insulation, foils, and sealing systems. Overlaps with Granab's acoustic-sealing function in multi-family construction, primarily serving DACH markets.
