What is the difference between WPC and PVC door frames?

In the world of construction and interior design, choosing the right door frame is crucial. It's not just about aesthetics; it's about durability and functionality. In recent years, WPC (Wood Plastic Composite) and PVC (Polyvinyl Chloride) have become popular choices due to their unique advantages. This article will take a deep dive into the differences between WPC and PVC door frames to help you make an informed decision.

WPC Door Frames: The Innovation of Wood Plastic Composites

WPC, also known as a Wood Plastic Composite Door Frame, is a new type of eco-friendly composite material made by mixing wood fibers and thermoplastic plastics (usually PVC) in a certain proportion and then extruding them at high temperatures. This unique combination gives WPC door frames the best of both wood and plastic.

Key Advantages:

  • Excellent Durability: WPC door frames have the solidity of wood but overcome its weaknesses, such as being prone to moisture, rot, and insect damage. Their exceptional waterproof and moisture-proof properties make them ideal for humid environments like bathrooms and kitchens.

  • High Strength and Stability: Thanks to the reinforcing effect of wood fibers, WPC door frames have excellent impact resistance and structural stability, so they are less likely to deform or crack.

  • Eco-Friendliness: WPC materials often use recycled plastics and wood scraps, reducing the reliance on natural timber and making them a sustainable choice.

  • Workability: WPC door frames can be cut, drilled, and painted just like wood, making them easy to install and highly versatile.

PVC Door Frames: A Traditional Application of Polyvinyl Chloride

PVC (Polyvinyl Chloride) is a widely used synthetic resin. PVC door frames are made by mixing PVC resin with various additives (like stabilizers, lubricants, and colorants) and then extruding or injection molding the mixture. Unlike WPC, it is a pure plastic product.

Key Advantages:

  • Superior Waterproofing: PVC is a non-absorbent material, so PVC door frames are completely waterproof, making them a perfect choice for wet environments.

  • Cost-Effective: The production cost of PVC door frames is generally lower than that of WPC, making them a more budget-friendly option.

  • Lightweight: PVC material is lighter, which makes transportation and installation easier.

  • Easy to Maintain: The smooth surface of PVC door frames resists dust and is very easy to clean.

How to Choose?

  • If you're looking for higher strength, better texture, and superior stability, and have a flexible budget, then a WPC Door Frame is an excellent choice. Its wood-plastic door frame characteristics give it a clear edge in appearance and feel, making it especially suitable for spaces like master bedrooms and living rooms where a higher-quality finish is desired.

  • If you have a strict budget and your primary need is water resistance, for a bathroom, balcony, or storage room, a PVC door frame is a more practical option due to its affordability and complete waterproof properties.


In conclusion, both WPC and PVC door frames have their own merits. WPC, with its superior overall performance and eco-friendly nature, represents a future trend in door frame materials. PVC, on the other hand, remains an indispensable choice in certain applications due to its excellent cost-effectiveness and waterproofing. By considering your specific needs and budget, you can use this analysis to find the perfect door frame material for your project.
