Internal walls in hospitals are built in two main ways: in plasterboard, meaning gypsum boards fixed to a metal stud frame and finished on site, or with pre-finished modular walls, manufactured at a plant and assembled dry. Both have a place in healthcare. The choice depends on the room, on the services the wall must carry and on whether the hospital stays open during the works.

What is a plasterboard wall and how is it built?

A plasterboard wall consists of gypsum boards fixed to metal studs, with insulation in the cavity where needed. On site the frame and boards are installed, the joints are filled and sanded, and finally the finish is applied: paint, vinyl sheet or other materials.

Plasterboard is economical, widely available and flexible during construction. Its limit in a hospital is that the final quality depends largely on workmanship on site, and that every later change means cutting, making good and refinishing the wall.

What is a pre-finished modular wall?

A pre-finished modular wall is a system of panels and frames manufactured at a plant, complete with surface finish and provisions for building services. On site the modules are fixed mechanically, with no wet trades.

In systems designed for healthcare the panels form continuous, cleanable surfaces, house medical gas outlets, power sockets, control panels, monitors and recessed cabinets, and can be opened to reach the services without demolishing anything.

What are the main differences?

Criterion Plasterboard Pre-finished modular wall
Where the finish is applied On site, with wet trades At the plant
Final quality Depends on site workmanship Checked at the factory before shipping
Dust on site Filling and sanding produce fine dust Dry assembly, reduced dust
Joints and surfaces Joints filled and sealed on site Continuous surfaces, engineered joints
Services integration Chases and openings cut on site Provisions planned in the design and made at the plant
Access to services The wall is cut and made good The panel is opened and closed again
Impact resistance Needs extra protection in exposed areas Depends on the cladding chosen in the design
Future alterations Demolition and rebuilding Modules dismantled and repositioned
Initial cost Lower Higher

Why does hygiene favour pre-finished walls in critical areas?

In an operating theatre or an intensive care unit, surfaces must be smooth, non-porous and resistant to the disinfectants used every day. A finish applied at the factory, under controlled conditions, is more uniform than one applied on site.

How the joints are made matters too. In plasterboard the joints between boards are filled and can crack over time and with impacts; in modular walls the joints are part of the system design and can be inspected and replaced.

What changes when the hospital stays open?

The clearest difference between plasterboard and modular walls appears on sites inside operational hospitals. Filling and sanding plasterboard produce fine dust, which has to be contained with barriers and filtration to protect patients on nearby wards.

A pre-finished modular wall arrives on site already finished and is assembled dry, so it reduces dust, noise and the duration of the works. The same applies in the years that follow: to maintain a service, a panel is opened instead of cutting a wall in an occupied ward.

When should you choose plasterboard and when a modular wall?

Plasterboard and modular walls are not mutually exclusive: many hospitals use both, each in the areas where it makes most sense.

  • Pre-finished modular walls: operating theatres, intensive care units, controlled-contamination rooms, isolation rooms, shielded radiology rooms, and in general areas with many integrated services or frequent alterations.
  • Plasterboard: offices, service rooms, storage and administrative areas, where hygiene and services access requirements are less demanding and the initial cost carries more weight.

The cost comparison should cover the whole life of the building, not only the supply price: time on site, days a ward is out of service, maintenance interventions and future layout changes are real costs, and they are where a modular system returns value.

How does ADAM approach hospital walls?

ADAM S.r.l. has manufactured partition systems since 1990 and has developed its SALUS system, the range dedicated to healthcare environments, since 2006: pre-finished panels with continuous, cleanable surfaces that can be opened for services maintenance, suitable for operating theatres and controlled-contamination environments. The ADAM range includes solid, glazed, metal and technology-integrated walls.

SALUS walls are part of a wider system offered by the ADAM Health division: medical doors, technical ceilings, recessed cabinets, pass-through boxes, X-ray shielding and the integration of monitors and PACS displays into the walls. SALUS walls are designed and manufactured at the plant in Bernate Ticino, near Milan, as described on the Manufacturing page.
