One of the problems of kitchen cabinetry today is the corrosion and decay of metal, wood, and MDF cabinets due to the moisture in the kitchen. Since PVC foam boards are waterproof, they are very popular choices in making kitchen cabinetry, especially for the sink cabinet.
In addition, the antibacterial property of PVC foam boards prevents fungal and bacterial growth in the humid environment under the sink.Since wood and MDF are not resistant to insect infestation and certain types of insects even feed on them, using PVC products can be a good way to keep insects away.
