This was originally a cedar deck that was rotten. It is on a roof top that is shared by two duplexes. The owner wanted something that was long lasting, light weight, and maintenance free so we went with PVC decking. This decking is the most expensive that Timbertech makes, they refer to it as XLM. It is very long lasting and durable and has dark color streaks going through it to make it look more realistic. This is a deck that will last a lifetime!
