Just compare the deck on the left built with Delta's vinyl planking material with the traditional wooden deck on the right. The Delta installation will look the same year after year with only a fraction of the care and maintenance of the wooden deck. Just hose it off or sweep it because our UV inhibitors and impact modifiers keep our decking from ever needing sealing, staining or painting. The non-porous surface cleans easily and will not stain. The UV inhibitors and light colors keep our decks cool to the touch in the summer sun and weather-resistant all year long. The decking material is guaranteed for twenty years and the fencing material is guaranteed for life-against cracking, breaking, abnormal weathering and discoloration. It's 100% recyclable and an environmentally friendly alternative to chemically treated wood.
