The truth about interior lining for food processing buildings

interior wall panels

When designing the interior walls for a food processing building, the main requirement is having a cleanable and sanitary wall. Such requirements include:

  • Hard, Flat, Smooth
  • No pits, cracks, crevices
  • Impervious and non-absorbent
  • Chemical resistant
  • Corrosion resistant
  • Durable
  • Easy Maintenance
  • Wear resistant
  • Water resistant
  • Properly installed, sealed, covered

The installation process should ensure that these properties are met throughout the floor to ceiling in the facility. Any windows should also adhere to the properties listed. There are many options used for food processing buildings such as Vinyl panels, FRP panels, Cement, or wood. We created a table for different types of building materials used.

Vinyl wall panels is recommended, because it has a seamless smooth surface and almost no maintenance requirements. With one of the fastest install times, vinyl wall panels saves a lot on labor costs.

Fiberglass panels is standard option for wall material and are commonly used in newly constructed facilities.

FRP, when properly installed and sealed with trim and fasteners between each panel, provides a durable surface. Fiberboard reinforced plastics come in sheets that require a pre-installed backer for the sheets to install on. However, if FRP panels are not installed correctly, or not maintained well, they begin to lose their durable, sanitary characteristics, which will end up in a costly and time consuming repair.

Ceramic Tile has a great reputation for resistance to water and chemicals. In wet processing areas, tile performs very well. The grouting processing provides a long installation process and improper installation may cause problems in operations. Being low on durability, impacts to tile often lead to cracks which may be vulnerable to vapor penetrating through the tile pieces. Careful maintenance is required for tiling.

Concrete has durability and water resistant properties but the surface is porous and needs a layer of paint and semi-gloss or gloss epoxy enamel.

Most building materials are not a complete solution. This means that they rely on additional materials to give the properties required such as durability, water resistance, chemical resistance, or seamless surface. FRP is reliant on adhesives, interpanel trim, and fasteners. Ceramic is reliant on grouting and glaze. Concrete requires paint, gloss, or epoxy. Not only do these new elements give room for error in installation process, but require constant maintenance throughout the building’s lifespan.


Duramax vinyl panels do not need any of these. Installation is the fastest by directly screwing the panels into the stud walls. There is no maintenance because there is no additional materials or coating required. Vinyl panels lasts a lifetime and have a warranty on rotting, peeling, corroding, and more.
