When it comes to exterior trim for homes and buildings, the choice of material is crucial. The trim not only defines the aesthetic appeal of your property but also plays a vital role in protecting structural elements from the elements. For decades, wood was the go-to choice for exterior trim, prized for its natural beauty and versatility. However, with advancements in building materials, aluminum and PVC (polyvinyl chloride) have emerged as strong contenders, each offering unique benefits and drawbacks.
This comprehensive guide delves into the key differences between PVC, wood, and aluminum exterior trim. We will examine their durability, maintenance needs, cost, environmental impact, and overall performance. By the end, you'll have a clear understanding of which material is best suited for your project, whether you're renovating an older home or building new.
Exterior trim is more than just a decorative feature. It serves several essential functions:
- Weather Protection: Trim seals joints and edges, preventing water infiltration and subsequent rot or mold.

While still used, especially for restoration work, wood trim is increasingly being replaced by more durable, low-maintenance alternatives. Homeowners seeking the classic look of wood often turn to engineered wood or composite trims, which offer improved resistance to the elements but still require some upkeep.
PVC trim has gained popularity due to its resistance to moisture, insects, and decay. Key benefits include:
- Waterproof: PVC does not absorb water, making it immune to rot, swelling, or warping.
- Insect-Proof: Unlike wood, PVC is not a food source for insects.
- Low Maintenance: PVC trim comes pre-finished, often in a crisp white, and does not require painting. If painting is desired, it must be done with specific paints suitable for plastics.
- Lightweight and Easy to Install: PVC is lighter than wood, reducing installation labor and costs.
- Fire Resistance: PVC does not support combustion, reducing fire risk.
Despite its strengths, PVC trim has some notable limitations:
- Thermal Expansion: PVC expands and contracts with temperature changes, which can cause joints to open or paint to crack, especially if dark colors are used.
- Aesthetic Limitations: While manufacturers have improved the appearance of PVC trim, some homeowners feel it lacks the authentic look and feel of wood.
- Impact Vulnerability: PVC can be dented or gouged by falling debris or hail, and repairs can be challenging.
