4 Key Differences Between WPC and SPB for Interior Design

When it comes to interior design, choosing the right materials is crucial for both aesthetics and functionality. Two popular materials that often come up in discussions are Wood Polymer Composite (WPC) and Solid Polymer Boards (SPB).

At a glance, they may appear the same, but they do differ in a way that makes one useful for a certain application as opposed to the other. It is important to comprehend these distinctions to make the right choices for interior design. Read on to get more information!

What are the Key Differences Between WPC and SPB for Interior Design?

In terms of appearance, durability, or sustainability, both WPC and SPB have their virtue and can be used interchangeably in interior design. Knowing these aspects will assist you in selecting the appropriate material that fits your design goals and requirements fully. Here are 4 major differences between WPC and SPB:

Composition and Structure

The first basis on which it is possible to compare WPC and SPB is their elemental composition. WPC is found in a combination of wood fibers and high-density polyethylene plastic. Such a combination allows WPC to have a look like natural wood in addition to increasing its durability as well as its resistance to water and insects. The plastic part is normally composed of polyethylene which makes the material flexible and easier to work with.

On the other hand, SPB Boards consist exclusively of plastic polymers and do not contain any wood fibers. This makes these boards entirely synthetic, providing a consistent shape and density throughout the material. Since wood fibers are not used in the production of SPB Boards, they are more resistant to moisture and temperature changes than WPC, making them very stable in different conditions.

Durability and Strength

Durability is another important aspect when it comes to choosing materials for interior design, especially for areas that are frequently used. WPC is considered to be quite strong and at the same time rather flexible. It can handle relatively high pressure and does not easily develop cracks and this is why it is used in places like flooring and decking. However, the use of wood fibers degrades WPC’s performance in extreme moisture and temperature conditions over time.

On the other hand, SPBs are acclaimed for their enhanced strength and durability. The all-plastic composition makes these sheets free from cracking, warping, or any other signs of damage that may be caused by environmental factors. This makes SPB an excellent option for areas that need more durability like the kitchen and the bathroom areas that come into contact with water and heat.

Aesthetic and Design Flexibility

Aesthetic appeal and design flexibility are two major factors that should be given attention in interior design. WPC has an appearance that closely resembles that of wood and this can be beneficial to designs that want to adopt a natural look. The WPC contains wood fibers, which can be processed to have different wooden grains and textures, offering many appearances.

On the other hand, SPBs are relatively more contemporary and have a standard look. As they are completely artificial, SPBs can be produced in different colors and surface patterns, producing a smooth and glossy or matt look. This makes it possible to achieve a more aesthetic look of the floor, especially in modern or modernist interiors where there is a need to achieve a uniform look.

Environmental Impact

The environmental impact of building materials is an increasingly important consideration. WPC is generally advertised as an environmentally friendly product since it contains recycled wood fibers and plastics. This recycling aspect may help minimize the waste and the impact of the material on the natural environment. But still, the manufacturing of WPC involves the use of plastic material which in one way or the other has its disadvantageous effects on the environment.

SPB Board Sheets, being entirely synthetic, do not involve any natural wood resources, which can be a plus from a conservation perspective. Nevertheless, the production process of SPB still depends on the use of petroleum-based polymers which are non-renewable. Although SPBs are strong and long-lived, their environmental cost is the utilization of non-renewable materials and the high energy required in the manufacturing process.


Both WPC and SPB offer unique advantages for interior design, and the best choice depends on the specific requirements of your project. WPC and SPB have their inherent advantages and disadvantages in interior design, so the selection will depend on your requirements. WPC has a natural aesthetic appeal whereas SPB has a longer lifespan and a more contemporary appearance.
