What is vinyl siding primarily made of?

Vinyl siding is primarily made of PVC (Rigid Polyvinyl-chloride), which is a type of plastic known for its durability, low maintenance, and resistance to various environmental factors, such as moisture and sunlight. PVC is favored in the manufacturing of vinyl siding because it can withstand significant weathering without cracking or fading, making it a popular choice for homeowners looking for long-lasting exterior solutions. Additionally, vinyl siding comes in a variety of colors and styles, but it retains its color and appearance due to the properties of PVC, which helps resist discoloration over time. This material also offers energy efficiency benefits as it can help insulate the home when paired with proper installation techniques.
