recent years, vinyl has become the siding market leader. It's made from
polyvinyl chloride (PVC), the same stuff that serves so ably in plumbing
drain lines. Certainly its primary appeal is that it doesn't have to be
painted. If properly installed, the upkeep is minimal. But, its popularity
continues to grow because of new product offerings and features such as
wood-like textures, shingle- and shake-style panels, more appealing trim
components and deeper colors. According to the Vinyl Siding Institute, shipments
have more than tripled since 1986.
Vinyl's biggest selling point remains its low maintenance. It usually can be washed clean with a garden hose. Material and installation costs are relatively low too.
