  • The natural look and feel of my new ash decking is second to none. So happy I went with WoodPlank over other options I considered like composite. It transformed my backyard into a beautiful oasis.
  • My contractor recommended I use this material for my new deck and wow, i am speechless. Not only did it show up right on time, but the end result is gorgeous. Nothing compares to the beauty of real wood.
  • I love the natural beauty it brings to my outdoor space, and the 25-year durability guarantee gives me peace of mind. I would definitely recommend WoodPlank to anyone looking for a top-quality decking option.

Unmatched Natural Beauty

Introducing our real hardwood decking made from sustainably sourced, premium-grade ash. It is the perfect choice to add a touch of natural beauty to your outdoor oasis.

Ash is known for its strength and resistance to rot giving it the durability to withstand high-traffic areas and climates with extreme weather conditions.

Why Choose Thermo Decking?

  • 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.

  • Heat Resistant Surface

    Thermo wood decking does not overheat in the sun so you can walk on it comfortably unlike most composite alternatives.

  • Manufacturer's Warranty

    25-year durability guarantee against rot and decay plus natural resistance to termites and pests.

Backed By Our 25-Year Durability Guarantee

Designed for an easy, low-maintenance experience, WoodPlank Ash Decking is fully-defected and factory sealed on all 4 sides so it arrives ready to install.

The combination of our thermal treatment process and factory seal protects your new deck against UV, fading, pests, termites, and other factors.

Frequently Asked Questions

All of our Modern Ash Decking is made from clear grade Ash that is sourced, milled and sealed in our North American production facilities. Each piece is thermally treated for added durability and stability before it is fully sealed on all 4 sides.

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 Cladding, you can apply a fresh coat of oil based sealant (Thompson’s WaterSeal Clear or Ready Seal) at any time.

All of our exterior decking options are treated to withstand weather of all types - hot sun, dry climates, humidity, or rainy seasons. Our Modern Ash Decking 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 3-4 weeks via UPS or an LTL carrier (we send tracking information once it ships).

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

Installation is super simple! We recommend using a hidden fastener system for the best result and appearance. Full instructions are included with every order.
