Why Solid Wood Paneling

The SWP Difference

▬

5/8″ Cove-Cut Profile

The concave cove cut creates a distinct shadow line between each plank, adding depth and visual rhythm that flat-cut paneling simply can't match. The 5/8" width amplifies this effect across large surfaces, making it ideal for statement feature walls.

↔

Pairs with Tambour

Every SWP profile corresponds directly to a Tambour variant. Mixing flat walls with curved surfaces in the same space? Run SWP on the flat sections and Tambour on the curves — same profile, same species, same finish. Seamless.

🌲

5 Species Available

Choose from Poplar, Red Oak, Maple, Walnut, and White Oak — all premium North American hardwoods. Poplar takes paint beautifully and is our most economical species. Oak, Maple, Walnut, and White Oak are ideal for stained applications.

🎨

Finish Your Way

Panels arrive sanded and ready for staining or painting. Pre-finishing the back face before installation is recommended — it equalizes moisture absorption and reduces the risk of cupping over time.

Before You Install

Storage, Handling & Acclimation

Acclimate First — Always

On receipt, store flat in a controlled interior environment. Allow a minimum of 48 hours to acclimate before finishing or installing. Stack with spacers between planks for air circulation. Solid tongue and groove panels are sensitive to moisture — acclimation ensures dimensional stability and reduces the risk of gapping or cupping after install.

Interior Use Only — Does Not Flex

SWP panels are solid hardwood tongue and groove — they will not bend around curves or corners. For curved surfaces, use the corresponding Tambour flexible panel in the same profile. SWP is not suitable for wet or high-humidity environments.

Installation

Step by Step

1

Prep the Surface

Wall or substrate must be clean, flat, dry, and structurally sound. Tongue and groove panels require a solid, even substrate — check for high and low spots before you start.

2

Acclimate — 48 Hours Minimum

Never skip acclimation. Stack planks with spacers in the installation room for at least 48 hours. Check moisture content if a meter is available — target 6–9% MC.

3

Pre-Finish the Back (Recommended)

Apply a sealer coat to the back face before installation. This equalizes moisture absorption on both faces and significantly reduces the risk of cupping — especially important for painted applications.

4

Apply Adhesive & Nail

Use a quality construction adhesive in continuous beads — perimeter first, then horizontal runs every 6″. Supplement with 15- or 16-gauge finish nails or brad nails through the tongue at each framing member.

5

Leave Expansion Gaps

Leave 1/16″ between adjacent planks and a 1/8″ gap at all perimeter edges. Solid wood moves across the grain seasonally — these gaps are not optional.

6

Finish After Install

Fill nail holes, sand lightly across all planks, then apply your chosen stain, paint, or clear finish. Apply in thin, even coats and allow full dry time between coats.

Installer Advice

Pro Tips

Check Your Moisture

High MC at install means shrinkage gaps later. Low MC means potential swelling and buckling. Target 6–9% before you nail anything down — a moisture meter is cheap insurance on a custom hardwood install.

Mix Planks from Multiple Bundles

Natural hardwood varies in color and grain. Pulling from several bundles and mixing planks as you work prevents banding — where one bundle's color is concentrated in one area of the wall.

Combine with Tambour on Curves

SWP on flat surfaces, Tambour on curved or radius surfaces — same profile, same species, same finish. Plan your layout before you start so the two materials meet cleanly at the transition.

Made to Order — Lead Time & Minimums

SWP panels are made to order in your chosen species. Standard lead time is 2–3 weeks from order confirmation. Minimum order is 21 pieces per species. For larger quantities, custom lengths, or project-specific requirements, contact White River Hardwoods for a tailored quote and timeline.

Perfect Toy for Large Dogs
Size: Medium, Style: Cheddar Cheese
I don’t normally leave reviews, but this toy is stellar and is a new favorite for my dog! She is a large dog (70lbs cattle dog lab mix) and I accidentally bought a medium, but it actually is a great size for her! So far this stands up to her chewing, but I may need to update in a few weeks to speak for durability but it really does feel solid. Most toys don’t last an afternoon once she starts chewing, so this has already won in that regard. The shape is perfect as well. She can gnaw at it, squeak, play fetch, play tug. It bounces when she throws it around herself. The fact it smells like stinky cheese is just an added bonus for her. All around, a very well designed dog toy!

Boxer Baby’s Favorite
Size: Jumbo, Style: Beef
This toy is my sweet girl’s absolute favorite. It was the first thing we gave her when we brought her home, and she has been obsessed with it since. She brings it from room to room, inside and outside. I would highly recommend this toy, however, we have gone through six in one year. They’re not very durable, especially with our boxer mix, who is a very heavy chewer. I’ve gotten the red and the blue, and she will only take red, which is fine with me because the blue STINKS. The red stinks too, but less so. The squeak is very loud, but she genuinely loves it so much that it’s hard to be annoyed by it. I’d say give the toy a try, you may be unintentionally giving them their favorite thing ever lol.

Design Hazard
Size: Medium, Style: Bacon, Size: Medium, Style: Bacon
I have one of these in a larger version I picked up at the petstore. This one I do not recommend. There is a whole in the center where the pet bites down and my doggies' teeth kept getting stuck in it. If you've ever had a toy get stuck in your pups mouth, you've seen how thet go nuts trying to get it out.

Cane Corso approved
Size: Jumbo, Style: Beef
I have two Cane Corsos, One is 80 pounds the other is 120 pounds. They can seriously destroy some toys very easily. These chewies have actually lasted for over six months at this point, which is pretty much miraculous. I bought them some more just so I always had plenty of them laying around as this discourages them from getting into trouble, chewing things they shouldn’t be chewing. They walk around with these and their mouths all the time and even after all these months, the squeakers still work. These are really high-quality and if you have a dog that just destroys toy toy, I highly recommend these. Even though they’ve had these for months, they go back to them to chew on and play with , it’s also really funny because they walk around with one and hanging out of their mouth and it looks like they’ve got a stogie hanging out of their mouth. If these toys can keep the interest and survive being mauled by these two giant Destructo mutts, then they must be really, really tough. I highly recommend these for super chewers. These even a hold up to having one dog, grab each end and then play tug-of-war with it. These guys can Easily go through A cow huff every day, but these toys are still going strong

Not a chew toy
Size: Medium (VALUE 2-Pack), Style: Beef
This is not for a voracious chewer...not durable. My dog destroyed in a matter of minutes, so the cost was high compared to the time it lasted. Maybe my expectation was too high but was disappointed in this product.
