Considering FRP in your Grow Room? Here's Why PVC Panels are Superior 

Tuesday, November 30, 2021

Fiberglass reinforced plastic (FRP) panels are frequently used to line the walls and ceilings in grow room facilities because, on paper at least, the upside of FRP can suit a grow room’s performance requirements. But along with FRP comes substantial downside.

Simply put, PVC panels like those made by Trusscore do the job and do it better. They have all the utility of FRP and they last longer, particularly in moist, humid environments like those found in grow rooms. 

Indoor growing facilities are demanding environments, and indoor grow room walls and ceilings are perhaps the most critical material choice to make. These are high-humidity rooms where moisture is always present and the humidity and organic, plant-based matter makes grow rooms susceptible to mold and mildew. For this reason, grow rooms must be exceptionally cleanable. 

Historically, operators of these facilities typically outfit the walls and ceilings of their facilities using FRP. This is, in part, because FRP handles many of the demands made by a grow room. It delivers a cleanable surface. Its white finish helps with lighting. And the waterproof capability of the plastic is designed to handle moisture and high humidity in a way drywall certainly can’t. 

Mold & Mildew Problems with FRP 

The problem with FRP is that the panel seams are penetrable. Over time, moisture is likely to cause the plastic to separate from its substrate. Moisture then seeps behind the panel and the cellulose-based substrate becomes a vector for mold, mildew and, well, major issues. Once FRP has begun to separate and allow mold growth, the only way to properly remediate the problem is to rip it all out and reinstall new material. 

This is exactly the type of downtime that makes grow facility operators cringe as it impedes the facility’s operation and adds to its maintenance costs, not to mention impacts to product yield or production schedules. 

In today’s market, there’s a clearly superior alternative to FRP panels for grow rooms. One that performs particularly well in a grow room environment – namely, PVC-based wall and ceiling panels. Chief among them in grow room performance? Trusscore. 

Trusscore Wall&CeilingBoard is a strong, easy-to-install, indoor grow room solution that has all of FRP’s upside with none of the down. 

A Better Choice Than FRP Panels for Grow Rooms 

Each Trusscore Wall&CeilingBoard panel is completely waterproof, so it’s unbothered by moisture and humidity. Like FRP, it comes in a bright, white finish that enhances available light and reduces grow room energy costs. Like FRP, it’s completely cleanable, even with a pressure washer, and resistant to chemicals. But the similarity ends there. 

Where Wall&CeilingBoard excels in a way that FRP can’t is in its design — Trusscore Wall&CeilingBoard is designed to last. The strength and durability of the product means it typically outlasts the life of the building in which it’s installed, delivering an exceptional return on investment for indoor grow rooms. 

Plus, Wall&CeilingBoard has no backing and is a standalone, pre-finished product, so there is no potential for separation and no need to ever paint. And because it’s impervious to water and has no cellulose component, it won’t support the growth of mold or mildew

Wall&CeilingBoard is a lightweight, easy-to-handle solution for your next grow room project. It installs much faster than FRP and with fewer people. The panels can even be applied directly over existing FRP in addition to drywall and bare studs. 

“We install Trusscore twice as fast, so it’s 50 percent of the labor. And it’s very easy to learn, too. I like to take some of my drywall installers that have never installed Trusscore and within two or three hours they're just flying down the walls. It's very easy to install.”

And let’s see FRP do this — Trusscore Wall&CeilingBoard integrates seamlessly with another PVC-based Trusscore product called Trusscore SlatWall. It’s a wall-based storage system that delivers added organization and utility, perfect for other areas of grow room facilities. Hooks, baskets, and shelves quickly snap into place on your SlatWall-equipped wall. Like Wall&CeilingBoard, Trusscore SlatWall is cleanable, installs quickly, and delivers the same durability and performance in a moist, humid environment.

The Bottom Line

Ultimately, FRP will perform adequately as a liner for indoor grow room walls and ceilings – until it won’t. Trusscore products, on the other hand, meet the same need but excel where FRP fails. They’ll last longer, which will lower maintenance costs, cause less downtime, and deliver dependable growing conditions day after day, year after year. 

And that’s growth you can count on.
