Cellular PVC Mouldings

An Alternative to Wood Mouldings

About Cellular PVC Mouldings

Cellular PVC Mouldings are a form of composite mouldings made from high-quality exterior grade PVC formulation. Cellular PVC mouldings are extruded from composite cellular formulation rather than machined from wood. Cellular PVC mouldings and trim offer uniformity and durability that makes them an attractive alternative to traditional wood mouldings. Not only are they easy to install, they’re easy to maintain as well.

At Chelsea Building Products we manufacture cellular PVC Mouldings and trim for manufacturers looking for a better solution for wood mouldings and trim. We can create cellular PVC mouldings for a variety of both interior and exterior applications, including casings, crown moulding, and more. No matter your needs, our team will listen and provide an innovative solution that meets your goals.

We work with various clients in many different industries, including but not limited to:

  • PVC extrusion manufacturers
  • Building product manufacturers
  • PVC fabricators

Cellular PVC Mouldings vs. Wood Mouldings

While both cellular PVC mouldings and wood mouldings have their benefits, PVC mouldings offer a more sustainable, long-lasting solution than wood can offer.

Wood trim moulding, while beautiful, is unfortunately more prone to damage and requires greater upkeep. Wood trim moulding is often used to provide visual detail to exterior structures, which are prone to unpredictable weather conditions like rain, snow, and hail. Wood mouldings are also prone to insects such as termites. As a result of their exposure to these elements, wood mouldings can rot, bow and decay rapidly. In order to keep their beauty and form, they require regular maintenance. This makes wood mouldings a costly alternative to cellular PVC mouldings.

Cellular PVC mouldings offer a more durable, weather-proof solution than wood mouldings offer. They do not require nearly as much maintenance, and keep their finish for years to come. In addition, PVC mouldings are much more cost-effective than wood mouldings. The costs of wood and preparing wood millwork are quite high and prices continue to rise. They also do not require nearly as much maintenance, so maintenance costs are greatly reduced. Wood mouldings are also not an environmentally sustainable option. Creating wood mouldings requires a steady supply of forests, but the number of forests available for use is rapidly depleting. PVC mouldings do not require deforestation since they are not made from wood. .

Since cellular PVC moulding lasts so long, the long term cost is less than wood mouldings while offering many of the same benefits. PVC mouldings can provide the beautiful look and finishes that wood has to offer, but without the disadvantages of wood mouldings such as increased maintenance.

Case Study


A large extruder of cellular sheet and boards asked our team to develop a cellular PVC moulding solution. This manufacturer wanted to reduce the cost of laminating and milling boards into mouldings, and saw no alternatives available in the market.


Chelsea Building Products developed an extruded cellular PVC moulding product line to replace wooden millwork. Our team designed an alternative to wood mouldings using only the finest exterior-grade PVC material. Our resulting cellular PVC mouldings lowered the customer’s costs while providing a higher quality finished product.
