PVC Vs. Pine Trim

Maintenance

• The draw of low-maintenance building materials is the driving force behind the entire PVC building materials industry. PVC trim is touted by manufacturers as very low-maintenance and durable, requiring only an occasional hosing off to remove accumulated dirt and pollutants. Pine trim requires periodic maintenance to protect it from the elements. Regular painting or staining increases the wear life of pine, preventing water damage. Pine can be susceptible to damage from termites in areas where the insects are prevalent and will require replacement long before its PVC counterpart, even without insect attack.

Cost

• Pine falls into the softwood category, which commands a lower price than exotic hardwoods. The prevalence of pine within the United States means pine trim products are readily available and do not require expensive cross-country shipping, leading to an overall lower cost. PVC trim requires extensive manufacturing and is not as widely produced as pine trim, so the material cost for PVC over pine will always be higher. The entire life cycle cost of PVC may be lower than pine due to decreased maintenance and a longer wear cycle, as well as a lower installation cost.

Design Options

• PVC trim is available in a range of colors suitable for both interior and exterior applications. PVC trim manufacturers typically offer product lines in colors that complement other PVC building materials, such as siding. Some PVC trim products are marketed as paintable, so homeowners that may consider a change in color scheme down the road may want to consider these options for greater design flexibility. Pine trim works well with both paint and stain, so color choices are limited only by the availability of suitable coatings. Knotty pine has a rustic appearance that appeals to many homeowners. The natural grain and texture of wood cannot be reproduced through man-made building materials.

Environmental Impact

• The adhesives required for PVC trim installation are typically solvent-based due to the chemical reaction necessary for proper fusion. Solvent-based adhesives can off-gas toxic fumes, causing a negative impact on air quality. Pine trim boards are generally installed with fasteners, such as nails, that have zero impact on air quality. According to the Healthy Building Network, the manufacturing process of PVC products produces toxic by-products that pose health hazards, including endocrine disruption, impairment of reproductive systems and even brain damage. Pine, on the other hand, is both a renewable resource and produces zero carbon emissions during its life cycle as a building material.
