Stop Comparing Trusscore to Drywall: The Thickness Question Is Missing the Point

I Used to Think Thickness Was Everything

When I first started reviewing wall panel specs—this was around 2021—I assumed thicker always meant better. I'd see a 1/2-inch drywall spec and compare it to a Trusscore panel at, say, 7/16-inch, and think, Well, that's a downgrade, right?

I was wrong. Kind of.

The thing is, thickness matters, but material properties matter more. And that's a distinction I didn't fully appreciate until I'd seen a few projects go sideways because someone picked a panel based on thickness alone—without thinking about what they were actually asking it to do.

The 'Thicker Is Better' Myth Comes From an Era When That Was True

Look, I get it. For decades, if you wanted a wall that wouldn't dent or flex, you went with a thicker gauge of drywall or plywood. That thinking is baked into construction. It's not stupid—it's just inherited from a time when material choice was basically: wood, drywall, or metal. All of which have predictable thickness-to-strength curves.

But that logic doesn't translate perfectly to PVC panels. Why?

Because PVC is a different class of material. A 7/16-inch Trusscore panel isn't trying to be 1/2-inch drywall. It's a solid polymer with different mechanical properties. It's impact-resistant in ways drywall isn't. It doesn't absorb moisture. It doesn't need mud, tape, or joint compound. Comparing thickness alone is like comparing the weight of a steel beam to an aluminum one—it tells you something, but not the full story.

Here's What Happens When You Focus on the Wrong Metric

I saw a project in Q3 2023 where a commercial garage had to be re-done because the spec called for 1/2-inch drywall for a 'durable finish.' The builder fought the spec, saying it wouldn't hold up. The client insisted. Eight months later, they had to tear out a section because moisture from the wash bay had compromised the drywall at the base. The total redo? Around $18,000—and that was just for one wall section.

Had they gone with a 7/16-inch Trusscore panel from the start, they'd have spent less on installation (no mud, no taping, less labor) and avoided the water damage issue entirely. The thickness number looked smaller on paper, but the real-world performance was actually better for that specific use case.

That's the kind of thing I've learned to look for: not the number on the spec sheet, but what happens when the material meets the actual environment.

The Real Question: Is It the Right Panel for the Job?

So here's where I get a bit blunt. If you're asking 'Is Trusscore thick enough?' without asking 'What am I asking it to do?', you're probably asking the wrong question.

Here are the cases where Trusscore works really well, based on what I've seen:

• Garages, workshops, and utility rooms: Moisture-resistant, easy to clean, no mold risk. Thinner material is fine because the priority is durability against cleaning chemicals and humidity.
• Ceiling panels in commercial kitchens: PVC panels handle grease and steam better than drywall. Thickness matters less than the material's non-porous surface.
• Retail slatwalls: Trusscore's slatwall is about 1/2-inch thick. It holds product just fine. Thicker would actually be overkill.

And here's where it's probably not the best choice:

• High-impact areas that need a 5/8-inch fire-rated assembly: If you need a specific fire rating, check local codes. Some commercial applications require a specific thickness for code compliance—and PVC panels may not fit that.
• Wet zones in shower stalls or pool areas: Trusscore is moisture-resistant, but no panel is 100% waterproof in all conditions. If you need a fully waterproof assembly with a proper waterproofing membrane, that's a different spec.

Bottom Line: Stop Comparing Thickness, Start Comparing Context

I've rejected specs because the designer picked a panel based on a thickness number that didn't match the job. I've also approved Trusscore panels for jobs where the client was initially skeptical. In every case, the deciding factor wasn't the thickness—it was whether the material's actual properties matched the environment it was going into.

If you're choosing between Trusscore and drywall, don't just ask 'Which one is thicker?' Ask: 'Which one will still look good and perform well in five years?' The answer might surprise you.

Oh, and one more thing—if you're looking to buy salt and stone products (which are a completely different category), you're in the wrong article. But hey, it happens. We all search for random stuff sometimes.
