What Is Curved Composite Decking?

Curved deck boards are formed through the process of heat bending which allows the boards to be molded into curved shapes.

This is an option for engineered decking, only — wood deck boards cannot retain their structural integrity when heat is applied. We believe Better Tech, Better Deck™, so we’ve developed capped polymer decking that can be heat-bent into eye-catching shapes.*

What Is Heat Bending?

Heat bending involves heating the deck boards up to high temperatures. Once heated, the boards can be bent into a curved shape. When the boards cool, they retain the new, curved profile.

Due to the high temperatures needed, our capped polymer decking line, TimberTech AZEK, is the ideal decking line for this process.

Because of the complex process of heat bending, you’ll need to work with an experienced contractor who is well-versed in TimberTech capped polymer decking. Remember that labor is an important part of your overall deck building cost, and budget should be considered as you learn whether a heat-bent deck is right for you.

What to Ask Before Choosing Curved Composite Decking

Before you dive into planning your curved composite deck design, you need to ask yourself these questions to ensure a curved design is the right one for you.

1.) Have I gone through the process of researching the factors that influence my cost to build a deck?

Factors that influence your costs include labor, deck design, substructure construction, materials used for the build, and fastening.

2.) Am I comfortable with potentially higher labor costs and an extended timeline for my project?

One of the larger cost factors to consider with a curved deck design is labor costs because of the heat bending process. The installation process may also take more time due to the specific substructure needed to suit your design.

3.) Do I know I want capped polymer decking (TimberTech AZEK®) for my deck?

TimberTech AZEK is the ideal material to use for curved designs thanks to its fully synthetic core and cap.

4.) Have I researched the municipal building codes for my area? Do I have the kind of space that lends itself to curved composite decking?

Your local building codes must allow you to build a curved deck design in the space available to you. If a curved deck is not code-compliant, you will need to alter your design.

5.) Will my curved deck require a railing?

In most areas of the US, decks over 30” tall will require a railing. Curving a railing and ensuring it is securely supported to the deck frame along the curve requires specific construction.
