Vinyl Siding and Exterior Accessories
Vinyl siding is the second largest use of PVC. It was used on 37 percent of new residential construction in 2000. Its use in siding has grown because of its low maintenance, durability and affordability. It also performs well in life cycle analysis. A comparison of vinyl siding to alternatives in the National Institute of Standards and Technology, Building for Environmental and Economic Sustainability (BEES 3.0) program shows that PVC vinyl’s performance is comparable to that of aluminum siding and much better than brick and mortar, stucco and cedar siding.
> Energy efficiency. Vinyl siding is significantly lighter in weight than some alternative materials, such as brick or fiber cement, which saves energy and fuel in transportation. New vinyl products such as insulated siding can deliver up to four times the insulating power of ordinary siding, keeping houses warmer in winter and cooler in summer, reducing thermal conductivity, and providing better impact resistance and protection from outside noise and air infiltration.
> Resource conservation. Vinyl siding and accessories are also durable products, which is increasingly being recognized as an advantage not only from an economic perspective but also from an environmental one. The longer a product lasts, the less energy or other resources that must be used to maintain the product or manufacture replacement products and the less scrap that must be disposed of. Vinyl siding manufacturers have improved yield to make more product with less vinyl. The vinyl siding industry has reduced material use, or material intensity, by 23% per unit of siding over the last 25 years while improving product performance and styling choices.
> Ease of maintenance. No paints, stains or harsh chemical cleaners need to be used to clean or maintain vinyl siding helping to conserve additional resources and time.
