Vinyl Planks - Interior

Note that interior beadboard paneling or beadboard planks do differ from the exterior equivalent. Both variants are made from some formulation of vinyl or PVC. Aside from the obvious that exterior beadboard tends to be thicker and stronger for impact resistance.

The difference is that better quality exterior products have UV inhibitors added to resist oxidation. This is why, vinyl lawn chairs that do not have these inhibitors added tend to develop a grey surface hazy that cannot be washed off. The problem is that the chemicals used for this UV protection can be very toxic in the event of a fire. Some building codes prohibit exterior PVC for interior applications. Interior beadboard products do not require UV protection; therefore do not require these additives.
