FRP vs. PVC Panels: The True Cost of Installation and Maintenance

For decades, Fiberglass Reinforced Plastic (FRP) was the default choice for commercial kitchens, car washes, and agricultural facilities. It was cheap, accessible, and got the job done. But as building standards evolve and labor costs climb, facility managers are discovering a hard truth: the initial price tag of FRP hides a massive long-term cost.

Today, high-performance PVC wall panels have emerged as the superior alternative. If you are planning a commercial build or renovation, here is why contractors are leaving FRP behind.


The Hidden Installation Costs of FRP

When comparing material costs side-by-side, a sheet of FRP often looks cheaper than a high-quality PVC panel. However, FRP cannot be installed on its own.

To install FRP, you need a solid backing material, usually moisture-resistant drywall or plywood. You also need heavy-duty adhesives, specialized trowels, and rivets to hold the panels in place while the glue cures.


This multi-step process requires significantly more labor:

  1. Hanging and finishing the drywall/backer board.

  2. Applying toxic adhesives across the entire surface.

  3. Pressing and riveting the FRP sheets.

  4. Adding trim and sealing the seams.


Why PVC Wins on Installation

High-quality PVC panels, like the 3/8-inch thick interlocking panels from DelPro 1638™, are designed for efficiency. Because they are structurally rigid, they do not require a backer board.


PVC panels screw directly into the bare wall studs. The tongue-and-groove design hides the fasteners and creates a seamless, watertight joint without messy adhesives. This cuts installation time in half, completely eliminating the cost of drywall, mudding, and gluing. When you factor in the labor savings, PVC is almost always the more economical choice on day one.


Long-Term Durability and Moisture Control

FRP is water-resistant, but the system holding it to the wall is not. Over time, moisture finds its way into the seams. Once water reaches the drywall or plywood backing, the adhesive fails. The FRP begins to bubble, peel, and harbor hidden mold.


PVC is 100% waterproof all the way through. A solid virgin PVC panel will not absorb water, rot, or delaminate, even when subjected to daily pressure washing in a car wash or dairy barn. The bright white, high-gloss finish naturally resists bacteria and easily wipes clean, maintaining its hygienic properties for decades.


Upgrading to DelPro 1638™ PVC Panels

As industries like indoor agriculture, advanced food processing, and healthcare demand even higher performance, the market is shifting toward premium wall systems. Standard panels do the job, but high-traffic facilities are increasingly upgrading to DelPro 1638™ PVC options.



What defines a premium DelPro 1638™ PVC panel?

  • Optimal Thickness: A 3/8-inch overall thickness provides maximum impact resistance. Going thicker often stretches the interior webbing, making the panel weaker, while going thinner sacrifices rigidity.

  • Width Engineering: DelPro 1638™ panels max out at 16 inches wide. Wider panels are prone to bowing and sagging under the pressure of insulation or heavy washdowns.

  • Virgin Exterior Grade PVC: Premium panels avoid recycled fillers that can make the plastic brittle over time, ensuring a brilliant white finish that won't yellow.


If you want to build it once and never worry about it again, skipping the FRP and investing in a premium interlocking PVC wall system is the smartest decision a facility owner can make.
