Waht is the difference between MDF and PVC mouldings?

PVC Mouldings

MDF (Medium-Density Fiberboard) mouldings and PVC mouldings are two different types of materials used for decorative and architectural trim in various applications. 

PVC Foam Mouldings: PVC foam mouldings are typically made from a type of plastic known as polyvinyl chloride (PVC) with added foaming agents. They are lightweight and have a closed-cell structure.

MDF Mouldings: MDF mouldings are made from compressed wood fibers, wax, and resin. It is a dense and solid material with no grain pattern.

MDF Mouldings: MDF is relatively heavy and solid, which can make installation more challenging due to its weight.

PVC Foam Mouldings: PVC foam mouldings are lightweight and easy to handle, making them easier to install.

Moisture Resistance:

MDF Mouldings: MDF is susceptible to moisture, which can cause it to swell, warp, or deteriorate over time if not adequately sealed or protected.

PVC Foam Mouldings: PVC foam mouldings are water-resistant and do not absorb moisture, making them suitable for outdoor and high-humidity applications.


MDF Mouldings: MDF is not as durable as PVC foam when exposed to environmental elements, making it better suited for indoor applications.

PVC Foam Mouldings: PVC foam mouldings are durable and can withstand outdoor conditions, such as sunlight and moisture, without significant degradation.


MDF Mouldings: MDF is generally less expensive than PVC foam, making it an economical choice for interior trim and decorative purposes.

PVC Foam Mouldings: PVC foam mouldings are often considered a premium material and may be more expensive, but they offer superior durability and versatility.
