Knauf drywall systems integrate gypsum plasterboards, mineral wool insulation, metal framing, and fixings to deliver internal partitions, wall linings, ceilings, and shaft encasements. The systems address thermal performance, acoustic separation, fire resistance, and moisture control across residential, commercial, healthcare, and education sectors. Key product families include the KW.111 single-layer partition for standard applications, the KW.112 double-layer system for enhanced acoustics, and the KSW.120 fire-rated shaftwall. Friction-fit glass mineral wool insulation holds position within the C-channel cavity without additional pins, maintaining consistent contact with the framing and supporting predictable acoustic and thermal outcomes over time.

What Are Knauf Drywall Systems?

Knauf drywall systems are certified, non-load-bearing assemblies designed for internal applications. They combine trusted gypsum boards, insulation materials—both glass and rock mineral wool—metal studs or channels, and proprietary fixings. According to Knauf, the systems provide the thermal and acoustic performance, moisture resistance, impact resistance, and fire safety required for a broad range of internal applications, with fully certified solutions backed by technical documentation and installation guidance.

The portfolio covers partitions (such as the KW.111, KW.112, KW.115, and KW.116 series), wall liners (KW.625 single-layer and KW.626 double-layer metal stud systems, KW.611 dot-dab adhesive fixing, and KW.623 bracket-fixed channel systems), and shaftwalls (KSW.120 fire-rated assembly with coreboard and gypsum layers for vertical service enclosures). Specialist variants offer intruder or ballistic resistance for public buildings and X-ray shielding for hospital environments.

How Does Friction-Fit Insulation Work?

Friction-fit insulation is designed to sit securely between metal stud frames without additional holding pins. Knauf Insulation glass mineral wool expands gently to fill the C-channel cavity, forming natural contact with the framing. This behaviour supports acoustic absorption across the surface area and contributes to steady thermal resistance. Installers appreciate the reduced need for adjustments, trimming, and accessory costs.

The 610 mm partition batt is engineered for 100 percent cavity fill, delivering edge-to-edge coverage that eliminates pinning and waste. Because the insulation remains correctly positioned within the wall cavity, the system maintains its intended performance over time. The product uses ECOSE Technology, a plant-based binder with low carbon and volatile organic compound emissions, and no added formaldehyde or phenols. The binder produces a low-dust, itch-free experience during handling.

What Performance Criteria Do the Systems Meet?

Performance varies depending on system configuration. Key criteria include:

  • Acoustic insulation: Multi-layer systems with increased board density and cavity-fill insulation deliver superior sound separation between rooms, critical for offices, hotels, and multi-family housing.
  • Fire safety: Double-layer gypsum board assemblies and fire-rated shaftwall systems provide robust fire protection for vertical service shafts and escape routes.
  • Thermal efficiency: Insulated wall linings improve the thermal performance of existing walls, reducing heat loss and contributing to energy-efficient building envelopes.
  • Moisture resistance: Specialist boards and system configurations address high-humidity environments in bathrooms, kitchens, and wet rooms.
  • Impact resistance: Braced versions (KW.625 Braced, KW.626 Braced) add structural stability and resilience in high-traffic or demanding applications.

Knauf emphasises that users should always check the technical documentation for every system before specifying, as performance is configuration-dependent.

Which Applications Suit Each System Type?

The KW.111 is a single-layer, non-load-bearing internal partition designed for typical commercial and residential projects. For projects requiring enhanced acoustic insulation and improved fire performance, the KW.112 double-layer partition adds a second gypsum board layer on both sides of the stud. The KW.115 and KW.116 high-performance multi-layer systems incorporate increased board density, additional insulation, reinforced bracing, and enhanced fixing, delivering maximum strength, stability, and acoustic separation for demanding environments.

Wall liner systems retrofit existing walls to improve performance. The KW.625 single-layer metal stud lining with insulation enhances acoustic and thermal characteristics; a braced variant adds impact resistance. The KW.611 dot-dab system bonds gypsum boards directly to the substrate using adhesive, enabling fast installation with minimal build-up. The KW.626 double-layer metal stud lining delivers enhanced fire, acoustic, and durability performance, with a braced version for superior rigidity. The KW.623 bracket-fixed metal channel system suits uneven substrates, allowing precise alignment.

The KSW.120 shaftwall system provides fire-rated enclosure of vertical service shafts, combining coreboard and gypsum layers for robust fire protection.

How Do You Specify the Right System?

Knauf offers a Systemfinder tool that combines gypsum plasterboards, insulation, furrings, linings, and fixings to match project requirements. Technical datasheets, installation guides, and performance certifications support accurate integration into project workflows. For specialist solutions—such as intruder resistance, ballistic protection, or X-ray shielding—direct consultation with Knauf's technical team ensures compliance with the necessary standards.

What Supporting Resources Are Available?

Knauf provides a Download Center with product datasheets, installation guides, and sustainability certificates. Production sites are equipped with facilities that meet high quality standards, and the company maintains a presence in more than 40 countries. Technical assistance, training through the Knauf Academy, and specification support are available to architects, engineers, and contractors. Case studies and project references illustrate system performance in education, healthcare, commercial, and residential sectors.

Practical take-away: When selecting a drywall system, match the performance criteria—acoustic, fire, thermal, moisture—to the building type and use. Friction-fit insulation simplifies installation and maintains cavity fill, supporting long-term performance. Always consult the technical documentation for the specific system configuration before specifying, and use the manufacturer's Systemfinder tool to ensure compatibility of boards, insulation, and framing components.
