White River Hardwoods · Solid Wood Paneling

1/4″ Cove-Cut Solid Wood Paneling

SKU SWP402POP · 5 Species · Made to Order

Solid Hardwood · Tongue & Groove · Does Not Flex · Made in the USA


The finest cove-cut profile in solid tongue and groove hardwood. At 1/4", the concave cut creates an exceptionally dense shadow pattern across walls and ceilings — 11/16″ thick, 4 5/16″ wide, 112″ long.

Proudly Made in the USA from Premium North American Hardwoods

At 1/4", the cove-cut creates the most intricate shadow pattern in the SWP lineup — a surface that shifts beautifully with changing light.

The SWP Difference

1/4″ Cove-Cut Profile

The concave cove cut at 1/4" creates a densely rhythmic shadow pattern — one of the most detailed profiles in the SWP collection. The fine pitch rewards close inspection while reading as rich texture from across the room.

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.

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.

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.

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.

International and Canadian Orders

We offer international shipping on most products. However, some large items or products containing fuel or hazardous materials may be restricted from international delivery. Please refer to the product and shipping notes during checkout for any restrictions. Unfortunately, if your country does not appear as a shipping option, we cannot deliver there.

Customs, Duties & Taxes

International shipments—including those to Canada—may be subject to import taxes, duties, tariffs, or other fees imposed by your country’s customs authorities. These charges are beyond our control and not included in our shipping rates. By placing an order, you acknowledge that any applicable tariffs or duties are the responsibility of the recipient. We cannot guarantee the exact costs or potential delays, as these may vary based on government regulations. If you have questions, we recommend checking with your local customs office for the most current information.

Shipping Costs

For international and Canadian orders, a minimum shipping charge of 30% of the order total will apply. In rare cases where actual shipping and handling costs exceed this estimate, we will contact you before processing the order.

Handling Charges 

Handling charges may be determined by applying the Minimum Charge or by calculating a percentage of the Net Order Total, whichever is greater, using the following FedEx Ground or LTL tables and adding any appropriate fees that will apply for a particular shipment.  Note that the Net Order Total is based on the White River Hardwoods (WRH) net cost to the customer, not the customer’s net cost to a builder, homeowner, etc.

The following calculations of Freight & Handling charges DO NOT APPLY to orders including Primed MDF products and/or Fabricated Products such as custom wood radius work or resin mouldings. Please contact Customer Service for a Freight & Handling quote for orders including exceptions. 

Customer is responsible for ALL freight charges.

It is the responsibility of the Customer to confirm that the delivery address meets the criteria for a business.

Any subsequent freight charges applied by a carrier for Residential Delivery, Redelivery, Lift Gate service, etc. will be the responsibility of the Customer and may be invoiced 2-4 weeks after delivery.

Residential Deliveries

Residential shipping with Less-Than-Truckload (LTL) is a preferred method to getting heavy and long length shipments to residential customers and jobsites.  Drivers are not allowed or responsible for delivering the order to the doorstep or placing in the garage.  The consignee must have “capable help or equipment” to unload the truck.  Consignee must unload truck using labor or equipment, the maser crate or top load can be opened to get the contents out.  All residential consignee (customers) have responsibility for receiving their orders in a professional manor.  For more support on this please call your White River customer support team member.

What’s a residential delivery fee?

A residential delivery fee is an additional service offered by the freight carrier for any and all shipments that are delivering to a residence. As LTL shipping uses dry vans and larger trucks, sometimes it can be difficult to maneuver residential streets. Delivery will be separate charges– so there will be a residential delivery charge.. This charge fluctuates depending on what freight carrier you are using to move your shipment, so ask your customer service team member  how much residential fees will be before you ship. If you’re quoted with residential pickup/delivery before you ship, the information will be on the Bill of Lading used at pickup.

What’s the deal with liftgates?

Because most LTL shipments are loaded and unloaded on docks, a liftgate will be needed for ALL residential pickups and deliveries. The carrier will need this information before making the pickup/delivery because not all trucks have liftgates on them. A special truck will need to be dispatched to accommodate the residential streets as well as liftgates, so it’s important to have this information on the BOL before pickup or delivery is attempted. Same as the residence charges, liftgate charges will be applied for pickup.

Residential Delivery & Appointments

Before the freight carrier makes a residential delivery or pickup, they will call the shipper/consignee to confirm the pickup or delivery time window. Because residences are not proper businesses, their hours fluctuate more than the standard 8am-5pm offices. This makes it vital to have the correct contact name and phone number on the BOL. It’s important to note the appointment for residential freight because this will add an extra day of transit in most instances, and possible further delays if the carrier can’t get in touch with the shipper/consignee to set the appointment. Setting the delivery appointment can only be done by the carrier, and is included in the residential charge, making it different from a notify consignee accessorial.

Inside Delivery

A common misconception with residential LTL shipping is that the freight carrier is a moving company, and will come into your house, pack up what you need to move, and put it on their truck. This is absolutely false. LTL freight carriers are NOT white glove movers. Because of liability issues, LTL carriers and their drivers cannot enter a residence under any circumstances. For residential shipping, the freight will need to be packaged and on the street or porch for the carrier to handle the freight. However, there is an additional service that can be paid for called Inside Delivery. Contrary to its name, the freight carrier STILL can’t take the freight inside your house. Instead, Inside Delivery can be used to pick up or delivery freight to a porch or garage – closer to the house than the street or curb.

Every effort will be made to minimize Freight & Handling charges. White River Hardwoods may contact the Customer with a recommendation to revise the shipment method at the time an order is packaged if a lower cost may apply.

It is the responsibility of the recipient to verify the condition of the goods received and note any shortages or damage on the carrier’s documentation at the time of delivery. 

  1. Our terms of sale are FOB Fayetteville. The responsibility for damage in transit is the carrier’s, whether it is visible or concealed damage.

  3. Open boxes within 15 days of delivery, inspect for concealed damages and report any discrepancies. No adjustments will be made for discrepancies not reported within 15 days of receipt.
  4. In case of a damaged LTL shipment, retain all packaging and notify the delivering carrier immediately. The carrier may wish to inspect the material. Place a phone call to the delivery carrier and confirm with a written report, holding a copy of the report for claim purposes.
  5. In case of a damaged Fed Ex package shipment, retain all packaging and notify White River immediately.
  6. We take every precaution to ensure safe arrival and have consulted with the carriers to develop packaging. Our responsibility for the goods ceases when the shipment is turned over to the carrier.
