The decking and railing industry was valued at $4.1billion in 2014 and is expected to continue steady growth through 2017 according to a new report from Principia. Part of this growth is due to the recovering economy, but there's also been a shift in demand to more expensive materials, such as capped composite decking, which is expected to grow at a 5% compounded rate through 2017.

Even with the higher demand for more expensive materials, 51% of homeowners surveyed that had recently built or planned to build a deck didn't understand the benefits of composite decking. The report also lists that large Home Centers and Direct Purchasers are increasing their share of distribution for decking and railing products.
