Knauf Gypsum Fiber: Strong, Eco-Friendly Drywall Systems 2026

Knauf Gypsum Fiber is a comprehensive range of boards, metal profiles, and accessories that form complete systems for dry walls, partition walls, and dry screed subfloors. These systems are designed to regulate humidity and improve the overall quality of your living space. Whether you're tackling a major renovation or a simple room update, understanding these materials can elevate your home improvement project.

What is Knauf Gypsum Fiber?

Gypsum Fiber (GessoFibra) is created by compressing a mixture of gypsum, cellulose, and water. The production process is free of harmful substances, making it a certified biocompatible product. It is highly impact-resistant, making it suitable for use in areas frequented by children, including schools. For your own projects, you can find complementary wall decor and sturdy shelving to match the durability of these walls.

Vidiwall® for Walls and Partition Walls

Vidiwall® boards can withstand a wide variety of stresses while providing excellent thermal and acoustic insulation. Noisy neighbors become a thing of the past. Using the proper construction system, you can easily hang heavy pictures, shelves, and wall cabinets without worry. Gypsum Fiber boards handle high loads—both concentrated and distributed—without deformation or sagging. Pair these sturdy walls with quality sofas and TV entertainment furniture for a complete living space.

Brio® Boards for Floor Subfloors

Brio® boards for floor subfloors are robust yet lightweight and thin. The joints are secured by a very stable step connection that ensures precise and rapid installation. They are also suitable for use with radiant floor heating systems. The standard version has a thickness of 18 mm, while the reinforced version is 23 mm, with respective weights of 22 and 28 kg/m².

The natural properties of gypsum add comfort to rooms. The boards absorb excess humidity and release it later without deforming. The floor is walkable just 24 hours after installation, allowing for fast, precise work and a clean job site. Complete your flooring project with stylish rugs and curtains to enhance comfort.

Mixed Solution: Combining Gypsum Fiber with Drywall

By combining the features of Gypsum Fiber with those of standard Knauf drywall boards, you get the Mixed Solution. This system unites the versatility of drywall with the high performance of Gypsum Fiber. It is an excellent cost-benefit compromise when a double layer of boards is needed. Depending on the required performance, one or the other layer can remain visible. For your workspace, consider pairing this system with functional desks and work surfaces and ergonomic office chairs.
