Homeowners today face a vast array of choices when it comes to exterior upgrades, with siding being one of the most important decisions. With so many options available, selecting the right material can feel overwhelming. Two popular choices are composite siding and cellular PVC. Both materials will undoubtedly boost curb appeal, provide protection from the elements, and provide long-lasting durability. Composite siding is standing out to builders and owners for its superior performance and low maintenance, making it a smart choice for those looking to balance aesthetics with long-term practicality.
However, even within that single category, not all composites are created equally.
Organic vs. Inorganic Composites
By definition, “composite” means “made up of various parts or elements.” Therefore, it is a broad category that encompasses a number of different materials. For the most part, composite siding materials can be broken into two categories: organic and inorganic.
Organic composites and inorganic composites differ mainly in their material composition and performance characteristics. Organic composites typically contain natural materials such as wood fibers, rice hulls, or other plant-based components, which can help reduce issues such as expansion and contraction. However, they are more susceptible to moisture absorption and other potential problems such as rot and mold. Because of this, organic composites must be sealed at end cuts upon installation. Organic composites are also often more difficult to recycle because of the complexities introduced by the natural fillers that are incorporated in the manufacturing process, such as wood flour or other biodegradable waste (food content, paper, cardboard, and more). Once installed, these organic materials can be subject to moisture absorption and degradation, making them less durable in certain applications and reducing their overall lifespan.
Alternatively, inorganic composites (including those with a mineral core and an acrylic cap such as Everlast siding) are designed for better stability and impact resistance. Inorganic composites are also much more resistant to moisture, rotting, warping, corrosion, and insect damage, ensuring that a building exterior remains sturdy and free of degradation for decades. Everlast siding is less susceptible to water and moisture intrusion, which can be attributed to its proprietary blend of inorganic minerals, polymeric resins, acrylic cap, and colorants, designed to be highly water-resistant.
Composite’s Cousin: Cellular PVC
Cellular PVC siding materials are similar to composites, but they lack the organic or inorganic component and they expand and contract more. While cellular PVC products can offer performance benefits, the biggest disadvantage is that they often need to be painted or coated, which leads to more maintenance over time due to fading and wear in the sun.
Despite the need for maintenance, cellular PVC does possess advantages in terms of durability and resistance to moisture. In essence, cellular PVC is a “synthetic wood” material (but it lacks the structural capabilities of real wood) that is made using PVC resin and a foaming agent that make it lighter and less brittle than rigid PVC. Its closed-cell composition means that the cells (or air pockets) within the panels are not interconnected. Because of this, the product does not absorb air or water, meaning it will not rot, warp, or be susceptible to insect damage. Its nonorganic nature also helps prevent mold or mildew growth, making it a good option for homeowners in humid climates.
However, homeowners should be mindful that although cellular PVC is resistant to many of the elements, prolonged exposure to sunlight can cause fading, necessitating periodic repainting. Cellular PVC expands and contracts considerably more, which can cause appearance issues or damage to the siding. This highlights the importance of proper installation because these added maintenance costs can become a burden for owners.
What Sets Inorganic Composites Apart?
When homeowners weigh their options between composite siding and cellular PVC, it is essential to consider not just the initial look but also long-term performance, durability, and maintenance. While both materials offer significant benefits, inorganic composites such as Everlast siding offer a distinct advantage and reign supreme when comparing all three materials.
Inorganic composites provide low maintenance, superior resistance to environmental factors, and exceptional long-term performance. These qualities make inorganic composites a smart investment for homeowners who want to enjoy a beautiful, durable exterior without the hassle of frequent upkeep.
