  • "After careful consideration we chose Thermo-Wood from WoodPlank because of the stunning grain patterns and easy maintenance. Delivery was quick and the final result was even better than we expected!"
  • “My project had some custom requirements so our architect worked directly with WoodPlank. They made it a breeze and were super accommodating to help us get the color, lengths and profile required for our design. Highly recommend!”
  • “As a contractor of 30+ years, I've installed a lot of siding. Its refreshing to work with a material is so easy to handle and doesnt require extra clips or fasteners. Saved a lot of time and headache! Great product.”

Less Work. More Impact. Wide Plank Cladding.

Our best-selling thermally modified hardwood cladding is now available in wide plank profiles.

Wider boards mean fewer seams, faster installation, and a sleek, modern look that sets your project apart. From the balanced proportions of 1x8 to the bold presence of 1x12, these profiles give you more freedom to design the way you want. 

Every board is precision-milled, finished to a profile of choice, and securely packaged so it arrives on-site ready to install.

Why Choose Thermo-Cladding?

  • Extended Lifespan

    Thermo treatment is a chemical-free process that results in unmatched durability and stability.

  • Lowest Maintenance

    The improved dimensional stability allows for extended maintenance intervals compared to other wood products.

  • Repels Moisture

    Thermo wood naturally repels moisture to prevent warping, shrinking and swelling on a molecular level.

  • Class B Fire Rating

    Reduced combustibility plus factory-applied, UV-resistant coating achieves Class B Fire Rating.

  • Natural Durability

    Built-in resistance to rot, decay, insects, and moisture for long-lasting performance.

Built to Last. Backed by WoodPlank.

Crafted for long-term performance with minimal upkeep, our thermally modified cladding is carefully milled and fully defected so you get maximum usable coverage.

The thermal treatment process enhances natural durability and stability, helping your exterior resist UV, moisture, insects, and decay — even in demanding climates.

Proudly made in the USA from sustainably sourced, FSC-certified wood so you can specify and build with confidence.

Amazing transformation!!!

We wanted to change the material on our dormers from vinyl siding to a wood material. I came across Woodplank online and decided to order samples. Samples arrived quickly and out of the 4 choices we chose Light Poplar. Shipping was fast and material arrived in perfect condition. Our contractor said installation was quick and easy and he even reached out to Woodplank customer service with a few questions which were answered thoroughly. I cannot express how happy we are with the results. I would highly recommend. This has changed the total look of our home. Including a before and after picture.

Fantastic product and team

I remodeled my outdoor deck/covered patio and wanted to do a tongue and groove wood ceiling. I looked at the big box stores for the tongue and groove and it seemed cheaply made (lots of knots, twisted boards, etc.) and would require a lot of treatment maintenance and upkeep. Looking for another option I found Woodplank, honestly at first I was skeptical. The reviews and promises almost seemed to good to be true (kinda like this one -ha). However, after chatting via the website with a helpful service rep, I gained the confidence to place my order of the pine wood. It arrived on time and was like something I hadn't seen before. I had my contractor install the wood and he continued to comment on how nice of quality this wood was for the job. Was an easy installation for him and it turned out even better than I could have imagined. Also, we did have some damaged in the shipment process, but the Woodplank team sent us some new material to cover it with no hassle. Overall this wood was more expensive than the other options, but it was totally worth it. We will order here again for the next project.

WoodPlank was recommended to me by my designer and I couldn't be more thankful.

WoodPlank was recommended to me by my designer and I couldn't be more thankful. I wanted the look of exotic woods but felt more comfortable with a locally made product and this turned out perfect. My carpenter said it was so easy to install due to us not needing any additional installation hardware or clips like the plastic alternative we were looking at. Thank you WoodPlank!

The Ash cladding has completely transformed the exterior of my restaurant.

The Ash cladding has completely transformed the exterior of my restaurant. It has given the building a modern and stylish look that sets us apart from the other units. The cladding is durable and has proven to hold up great under heavy rain and sun. The installation process was quick and efficient. I highly recommend WoodPlank Cladding to anyone looking for a high-quality and visually appealing solution for their commercial space

Frequently Asked Questions

All of our Modern Exterior Cladding is made from 100% authentic, thermally treated wood, clear grade hardwoods that are sourced, milled and sealed in our North American production facility.

This is dependent on your vision and preferences for design. The siding can be installed with no regular maintenance required which will allow the wood to develop into a beautiful silver color over time. If you wish to maintain or restore the original color of the Modern Exterior Wood Cladding, you can apply a fresh coat of oil based sealant (Thompson’s WaterSeal Clear or ReadySeal Walnut) at any time.

All of our cladding options are treated to withstand weather of all types - hot sun, dry climates, humidity, snow and rainy seasons. Our Modern Exterior Cladding is naturally water repellent due to the thermal treatment process, and then we take the added step of applying a UV resistant treatment and oil based sealant on all 4 sides.

We ship anywhere in the country in 2-3 weeks via UPS or an LTL carrier (we send tracking information once it ships). (Lead times may vary depending on season)

We accept returns/exchanges within 30 days from your delivery date. Please refer to our Refund Policy here.
