What Are Paddle Boards Made Of? | SUP Construction

The construction of paddle boards varies depending on the material used. Inflatable SUPs are typically crafted out of durable PVC material, while rigid SUPs are typically made with a range of materials, including fiberglass, foam, and plastic. Each of these materials has its own unique advantages and trade-offs.

Materials used

The materials used to construct paddle boards come in many forms. To ensure durability and strength, most boards are made of a combination of materials. Depending on the type of boards chosen, the core materials can include anything from plastic and wood to foam and fiberglass.

The most popular type of paddle board is the inflatable SUP. As the name suggests, these boards are made of PVC or urethane material and are filled with air or pressurized with a hand pump. This lightweight and versatile material allows for easy transportation and storage, making them ideal for paddlers of all levels.

Rigid SUPs are constructed with materials like fiberglass, carbon fiber, and epoxy resin. These boards are known for their superior performance and are commonly used by advanced paddlers who are looking for speed and agility. Unlike inflatable boards, rigid boards are much heavier and require more maintenance; however, they are also more durable and can handle more wear and tear.

Inflatable SUPs

Moving on from the discussion of board shapes and sizes, let’s now consider the materials used to make paddleboards. Inflatable stand-up paddleboards (SUPs) have become increasingly popular in recent years, due to their convenience and portability. When deflated, they are easy to store and transport, making them a great option for those who don’t have the space to store a large paddleboard.

An inflatable SUP is constructed with a multi-layer laminated fabric, similar to what is used to make river rafts and other inflatable boats. This fabric is strong and durable, and the seams are reinforced to make it even stronger. The fabric is then glued to the board’s core, which is typically made of a lightweight foam material. The core is what gives the board its shape and its buoyancy, allowing it to float on the water.

For additional strength and durability, an inflatable SUP may also have a layer of PVC on the top and the bottom. This PVC layer is designed to protect the board from damage when it is dragged across rocks or other rough surfaces. The PVC layer also provides a waterproofing barrier, keeping the inner core dry and helping the board maintain its shape.

Inflatable SUPs are a great option for those who value convenience and portability, offering a lightweight and durable solution for enjoying the water.

Rigid SUPs

Rigid SUPs

Rigid SUPs are traditionally made from either fiberglass or epoxy resin materials, creating a strong and durable board suitable for a variety of different activities. Fiberglass is a combination of woven glass fibers and a resin matrix that is then molded into the shape of the SUP. Epoxy resin is a combination of two different chemicals, glycidyl ether of bisphenol-A and a polyamine hardener, which are combined to create a solid material.

The fiberglass and epoxy resin layers are then laminated with a foam core that provides a lightweight and buoyant base. The core is usually made of expanded polystyrene foam and is either foam-cored or honeycomb-cored. The foam core is then vacuum-sealed between the fiberglass and resin layers to create a strong and stiff board that is resistant to damage and flex.

The shape and design of the board can be customized to suit individual preferences and paddling needs. The boards come in a variety of shapes, sizes, and thicknesses, allowing riders to choose a board that is right for them. There are also a variety of additional features that can be added to the board such as fins, grab handles, and leash plugs.

These features are designed to make the board more comfortable and easier to use. With a rigid SUP, riders can expect to have a stable and durable board that is perfect for a range of different activities.

How Paddle Board Materials Affect SUPs

Solid paddle boards are typically constructed with an EPS foam core and a combination of glass and carbon fiber layers, resulting in a lightweight yet durable board.

Wooden paddle boards bring a unique, organic aesthetic to the surf, crafted from sustainable wood and fiberglass for a blend of strength and beauty. PVC paddle boards are the most durable of the bunch, made with a thick layer of polyvinyl chloride that is both lightweight and buoyant.

Solid paddle board construction is one of the most versatile and reliable ways to get out on the water and find the board that will suit you best.

Wooden Paddle Boards

From the solid construction of fiberglass and plastic paddle boards, we move on to the warm, classic look of wooden paddle boards. Wooden paddle boards offer a beautiful, timeless look that can be enjoyed both in and out of the water. While not as durable or lightweight as fiberglass or plastic paddle boards, wooden paddle boards still have a lot to offer.

Wooden paddle boards are built from a variety of hardwood veneers, such as cedar, mahogany, and balsa. These veneers are laid up in layers and then vacuum-sealed and laminated together to create a strong, stiff board.

This layering process helps to protect the board from water damage and also makes the board more buoyant in the water. The wooden boards are also often treated with a special sealant to make them even more water-resistant.

The look of wooden paddle boards is unmistakable, with their unique grains and colors giving them a classic, timeless appeal. They are also incredibly stable in the water, making them a great choice for beginner paddlers.

The wooden construction also helps to dampen some of the vibrations, providing a more comfortable ride. Wooden boards are also often more affordable than other paddleboard materials.


Aesthetics aside, the method of construction is what really sets paddle boards made from PVC apart. The process starts by combining two layers of PVC. In between these layers, a number of reinforcements can be added to provide extra rigidity, including a layer of mesh and foam or stringers.
