What is drylining?
Drylining systems—commonly referred to as drywall or plasterboard systems—are a popular and efficient method for constructing internal walls, ceilings, and partitions within buildings. These surfaces are visible from inside a building and are essential for ensuring the safety and security of both occupants and the general public. They serve as the primary means of passive fire protection, acoustic separation, and thermal resistance. These systems are commonly used in both residential and commercial properties because they are versatile, cost-effective, and easy to install.
Drylining Systems
Typically, drylining systems consist of the following components:
Insulation: Insulation can be made from stone or glass mineral wool, or various types of chemically manufactured insulation boards. Its purpose is to enhance fire safety, acoustic performance, and thermal efficiency.
Plasterboard: This is made with a gypsum-based core that includes various additives based on performance requirements, all sandwiched between two layers of heavy paper.
Framing: The framing is usually metal but can also be timber. It may be classified as either non-loadbearing or loadbearing, depending on the structure of the building.
Fixings: These are specified to mechanically secure the plasterboard to the framing system.
Jointing Materials: This includes a jointing slurry, which can be either powdered or ready-mixed, and may air-dry or chemically set. Additionally, jointing tape is used, which can be scrim (fiber), self-adhesive, or paper. Jointing materials help create a seamless finish between the plasterboards.
Plaster: Generally gypsum-based, but in some cases, it can be marble-based. Plaster can be supplied in powdered or ready-mixed forms and should always air-dry. Drylining is typically specified to be finished either Tape and Jointed (T&J) or plastered.
Mastic: Mastic is used to ensure that drylining is correctly sealed to adjoining materials. This helps meet fire safety, acoustic, smoke, and air permeability requirements.
Drylining systemization is crucial for building performance and comes in various systems to create a safe and functional environment.
- Single Stud Partitions: HadleySOLO systems can be non-load-bearing, featuring a single central stud that is clad on both sides with plasterboard.
- Twin Stud Partitions: HadleyDUO or HadleyBrace systems are non-load-bearing, consisting of two sets of studs with a central cavity that are clad on both sides with plasterboard.
- Resilient Bar Partitions: HadleyHUSH systems can be non-load-bearing. They include a single central stud to which HadleyResBar is applied on one or both sides, with plasterboard cladding on both sides.
- Staggered Stud Partitions: HadleyStagger systems are non-load-bearing and consist of two sets of studs positioned within a wider track, staggered left and right, and clad on both sides with plasterboard.
- Shaft Wall Partitions: HadleySHAFT systems are non-load-bearing and feature a single central stud clad on one side with plasterboard. Plasterboard is also fitted between the studs on the opposite side.
- Linings: HadleyLINE or HadleyShield systems are non-load-bearing, with either an unbraced single stud clad on one side with plasterboard, or a braced liner stud that is clad on one side with plasterboard.
- Ceilings: HadleyMF systems, which are non-load bearing but may help support load-bearing structures for fire safety. This system is suspended from a structure to create a grid that is clad in plasterboard on the underside.
- External walls can be constructed using HadleySFS systems, which may be loadbearing or non-loadbearing. These systems consist of a single central stud, to which plasterboard is attached on the interior face, while a sheathing board and other facade system components are applied externally.
