Application
The Knauf GIFAfloor DB Green raised access floor system is designed for office and commercial environments, where sustainability, fire safety, and acoustic performance are key.
Typical Applications
- Office buildings – especially open-plan spaces using carpet tile finishes.
- Corporate workspaces – accessible raised floors for easy service integration.
- Sustainable construction projects – low-carbon, recyclable solution aligned with green building standards.
- Mixed-use commercial spaces – when combined with FHB T&G on pedestals, provides a hybrid system capable of handling both soft and hard finishes in one continuous floor.
This makes DB Green particularly suitable for modern workplaces prioritising sustainability, acoustic comfort, and regulatory compliance, while retaining the flexibility of a fully accessible raised floor system.

Description
The Knauf GIFAfloor DB Green system is a sustainable raised access flooring solution designed for office and commercial environments. Manufactured from low-carbon gypsum fibre panels, it provides high structural performance while significantly reducing environmental impact.
Material Composition & Construction
DB Green panels are made from homogeneous gypsum fibre elements, produced with:
- Minimum 70–80% recycled content
- No plastic, steel, or timber components
Unlike traditional raised floor panels, DB Green is manufactured without ABS edge bands, resulting in a completely flat surface with a bevelled edge finish.
This construction simplifies recycling at end of life and allows the seamless installation of loose-laid textile coverings such as carpet tiles.
Performance & Standards
- Fire safety: A1 non-combustible fire rating, tested to REI60.
- Acoustic performance: Excellent airborne and impact sound insulation due to panel density.
- Structural loading: Conforms to BS EN 12825: Class 1–3 performance requirements.
- Void heights: Compatible with pedestals up to 1400 mm.
- Indoor Air Quality: Eurofins Gold certified, Red List Free.
- Sustainability: EPD available, low embodied carbon, fully recyclable at end of life.
Features & Benefits
- Fully accessible raised floor.
- Non-combustible A1 fire rating.
- Excellent acoustic properties.
- 70–80% recycled content.
- 100% end-of-life recyclability.
- EPD certified and Eurofins Indoor Air Quality Gold.
- Low embodied carbon compared to conventional systems.
- Manufactured without steel or plastic edges for easier recycling.
- Compatible with office-standard finishes, especially loose-laid carpet tiles.
System Integration
DB Green is designed primarily to receive loose-laid carpet tiles, making it ideal for office environments. Where hard or continuous finishes are required, the Knauf GIFAfloor FHB T&G System on pedestals should be specified. Both systems can be installed side by side, creating a unified raised floor solution from a single manufacturer.
