Load bearing T&G raised floor / hollow floor system manufactured from highly sustainable gypsum fibreboard panels. Suitable to be installed directly onto pedestals and receive finishes directly
Suitable for a wide range of applications including:
Knauf GIFAfloor creates strong versatile flooring systems
Knauf GIFAfloor systems use highly engineered, structural dry screed panels made from sustainable materials. Fibres from wholly recycled paper are blended with a mix of natural and flue gas desulphurised gypsum to create non-combustible gypsum fibreboard panels with an A1 fire rating.
Knauf GIFAfloor panels are manufactured in a lamination process and pressed to the optimum density, resulting in an inherently strong and consistent product.
Engineered tongue and grooved edge profiles ensure a strong bond when laid, creating robust monolithic floors with excellent load-bearing capability, the ideal substrate for a wide range of finishes, including natural stone or porcelain finishes. The addition of frames and panels can be incorporated to give access into the void below the floor.
GifaFloor is a fantastic alternative to traditional wet screed as there is no long drying time. The floor is walkable within hours of being installed
Features and benefits:
