Blog Entry: 1. Thermal Expansion 4x8 pvc foam board is made from a honeycomb, cellular structure of polyvinyl chloride. The honeycomb makeup of the product means that it’s completely impervious to moisture, even when cut. Unfortunately, this can lead to issues all its own, such as thermal expansion. When the PVC gets hot, such as when it sits directly in the sun, the trim will actually expand or grow. If will then shrink again once it cools. This won’t damage the trim, but it can cause issues with its bonding to other surfaces. It may also cause the paint on its surface to peel and crack. For that reason, you cannot paint PVC trim in a dark color; the cracks become very obvious over time. 2. Not an Eco Friendly Material PVC trim is made from a type of plastic. This plastic is difficult to produce and gives off harmful VOCs both during its manufacturing and after its installation, for up to 5 years. And while it is technically possible to recycle it, most recycling plants will not receive it, so if you decide to replace it at any point in time, it is likely to go into a landfill. 3. Yellowing Nail Holes To avoid the problem of peeling paint, many homeowners choose to leave their PVC trim in its natural white state. When the trim is nailed or screwed into place, the nail holes are usually covered over with some type of vinyl spackle. This gives the boards a smooth appearance. Unfortunately, that vinyl spackle is likely to turn yellow over time. And because the PVC trim itself remains white, the yellow stands out very clearly, detracting from the appearance of the trim. 4. Easily Dented and Gouged Many people believe plastics like PVC to be a durable material, but in fact the trim can be easily dented, gouged, or damaged by falling debris. If a tree limb on your property were to come loose in a storm and hit your trim, or if you were to experience a hail storm on your property, you would find that the trim would sustain a lot of damage. Most of this damage can be fixed either by heating the boards or filling them with a putty, but this is a lot of maintenance and work – the very thing most homeowners wanted to avoid in the first place by opting for the PVC.
