Why polypropylene siding? To shape things up.

Cedar planks and shakes are known for their deeply grained pattern and natural beauty. But just like wood, real cedar is vulnerable to the damaging affects of water over time — swelling, rotting, degrading the finish, and insect infestations. Polypropylene siding gives you the best of both worlds:

  • Aesthetics: the highly textured, three-dimensional surface is recreated with injection molding technology — molds created from real cedar to look as natural and random as Mother Nature intended; polypropylene siding comes in a variety of styles — from hand split shakes to half rounds and everything in between — which can be used over the entire house or simply to highlight gables or window boxes; and even though the color won’t fade, many manufacturers offer a palette of “weathered” finishes for another level of authenticity.
  • Durability: polypropylene siding is known for its exceptional stability and superior impact resistance; it will never crack, warp, rot, or split because it’s impervious to moisture; and if that’s not enough, it’ll never need painting or other kinds of maintenance associated with wood or fiber cement — just a simple wash down of soapy water and a soft bristled brush.

Manufacturers can certify their polypropylene siding if it meets or exceeds the industry standard for quality, ASTM D7254, as verified by an independent, accredited quality-control agency.
