Types of operating room wall (OBS) Materials
The choice of wall material in your OBS directly impacts sterility, cleaning, and sustainability.
Stainless Steel
Stainless Steel is in the OR is usually AISI 304 flat panels. It is non porous but does require clips or nails to attach it to a sub structure. The surface requires an anti-corrosive finish to prevent oxidation/rust. Cut-outs for monitors, electric outlets, accessories, etc. can be done at the jobsite.
Glass
Glass is a non-porous, flat panel made from natural raw materials. Panels are attached to a steel substructure utilizing clips or screws. The surface does not require additional coatings or finishes. Cut-outs for monitors, electric outlets, accessories, etc. are generally specified and precut at the factory.
Some advantages of glass in the OBS environment:
- Electromagnetic Shielding – Glass inherently provides electromagnetic shielding. Additional shielding can be achieved via added insulation as needed.
- Noise Protection – Up to 33 dB without additional insulation. Higher sound insulation can be achieved by additional insulation in the substructure.
- X-Ray & Laser Protection – A special coating on the back of the glass scatters light to reduce reflection. The reflection of the laser light is less than 6% depending on the color of the coating.
- Hygienic Protection – Glass is nonporous, does not have joints, and provides for a smooth surface. This makes it highly cleanable. These properties also make the glass easier to clean.
- Fire Protection – Glass and substructure are inherently non-flammable. Insulation can be added for additional protection.
HPL (Laminate)
High Pressure Laminate (HPL) panels are made of a resin impregnated kraft paper, a decorative paper, and a clear melamine overlay. These sheets are bonded at high pressures and temperatures to substrates such as medium density fiberboard (MDF) or particleboard. Cut-outs for monitors, electric outlets, accessories, etc. can be done at the job site directly.
Drywall
Drywall is a porous, flat panel made of gypsum plaster sandwiched in between two sheets of thick paper. Panels attach to metal or wood studs using nails or screws. Cut-outs for monitors, electric outlets, accessories, etc. are finished at the jobsite. Exposed surfaces must be finished with paint, epoxy, or other materials after installation to protect the visible paper layer.
