Fencing & Decking

Stabilizers. Stabilizers improve PVC’s heat stability, which strengthens the material both during the manufacturing process and in the long term. In the past, lead and tin have been used to stabilize PVC, but many manufacturers are shifting to non-toxic stabilizers such as calcium and zinc. You can avoid health risks by selecting a conscientious manufacturer. Take the time to ask your contractor which stabilizer is used in the vinyl fencing you’re considering.

Titanium dioxide. Look for higher levels of titanium dioxide in the top layer of vinyl. A long-lasting vinyl fence will have 10-12 parts per 100 of titanium dioxide in the top layer. This protects it against UV damage and helps maintain the color.

Precipitated calcium carbonates. These improve PVC’s impact strength. Without this or similar compounds, a swift golf ball or baseball may pierce vinyl fencing. PCCs are thought to be safe for the environment and humans, which makes sense since most seashells are composed of calcium carbonate.
