British Gypsum Internal Partitions and Wall Systems

British Gypsum provides a comprehensive suite of lightweight, non‑loadbearing internal partition and wall systems designed for use across virtually all building types, including private housing, apartments, commercial premises, educational and healthcare facilities, and industrial environments. These systems use drylining techniques with metal framing and plasterboard linings to deliver reliable performance in fire resistance, acoustic insulation, impact resistance, and height capability. All systems are tested to BS EN fire standards, with supporting evidence available for BS 476 where required. 

The range covers everything from simple space‑dividing walls to high‑performance solutions for demanding acoustic or structural environments. Each system is engineered to meet specific performance criteria while remaining quick to install and adaptable to project needs.

Key Systems

GypWall Resilient

• A system designed to improve acoustic performance by reducing sound transmission through the wall structure. It typically incorporates resilient elements—such as acoustic studs or channels—to limit vibration transfer. This makes it suitable for residential and commercial settings where enhanced privacy or noise control is required.

GypWall Single Frame

• A versatile, standard metal stud partition system using a single frame of Gypframe studs and tracks. It supports a wide range of plasterboard linings and can be specified for different fire, acoustic, and height requirements. This is the core system for general internal partitioning.

GypWall Single Frame Enhanced

• An upgraded version of the standard single‑frame system, offering improved performance—often in terms of acoustic insulation, fire resistance, or robustness. It is used where higher‑than‑standard performance is needed without moving to a twin‑frame arrangement.

GypWall Staggered

• A single‑frame system with staggered studs to reduce direct sound paths between sides of the partition. This configuration significantly enhances acoustic performance while maintaining a relatively slim wall thickness, making it ideal for multi‑occupancy buildings such as hotels or apartments.

GypWall Twin Frame Audio

• A high‑performance acoustic system using two independent metal frames separated by a cavity. This design minimises structural sound transmission and is used in environments where superior sound insulation is essential—such as music rooms, cinemas, studios, or high‑spec residential units.

GypWall Twin Frame Braced

• A twin‑frame system that incorporates bracing to provide additional stability while still maintaining improved acoustic separation compared with single‑frame systems. It is suitable for taller partitions or areas requiring a balance of structural rigidity and acoustic performance.

GypWall Twin Frame Independent

• A fully independent twin‑frame system where each frame is structurally separate. This maximises acoustic isolation by eliminating direct contact between the two sides of the wall. It is used in the most demanding acoustic applications, such as performance spaces or specialist commercial environments.

Typical Characteristics

While performance varies by specific system configuration, British Gypsum partitions commonly offer:

• Fire integrity and insulation ratings from 30 minutes upwards
• Airborne sound insulation typically ranging from 30 - 50 dB, depending on system type
• Duty ratings from medium to severe, suitable for schools, hospitals, and high‑traffic areas
• Heights from around 2.5m to over 3.4m, with specialist systems capable of more
• Partition thicknesses from approximately 75mm and over 100mm

British Gypsum’s internal partition systems offer a structured hierarchy of solutions—from simple, economical walls to highly engineered acoustic and fire‑resistant systems. The GypWall family provides designers and specifiers with a flexible toolkit to meet regulatory requirements, performance targets, and architectural intent across a wide range of building types.
