Sustainability Information

CertainTeed respects the environment through the responsible development of sustainable vinyl and polymer siding products and systems.

CedarBoards™ offers:

  • 60% recycled content
  • Participation in LEED and NAHB
  • Benefits such as:
  • Resource Efficiency — Our vinyl and polymer products are typically made using some recycled products. CedarBoards D6" Insulated siding contains 60% recycled material. Using recycled material protects our environment by finding a use for material that would otherwise be landfilled. In addition, our manufacturing plants regrind and recycle products that do not meet our rigid manufacturing specifications. This regrind is then incorporated into the manufacturing process. In fact, one of our plants has achieved nearly 100% recycling of all plant waste.   Using materials that contain recycled materials can earn up to 2 points under LEED 2009 and 0.5 points per product for LEED H. CertainTeed vinyl siding, polymer siding and trim are typically made using some recycled content. CedarBoards D6" Insulated siding contains 60% recycled content.
  • Energy Efficiency—When they are installed properly, vinyl siding and polymer siding create an efficient building envelope that does not conduct heat or cold. Some products—like our CedarBoards Insulated Siding—can actually increase the R-value of the building envelope, which reduces energy consumption and related CO2 emissions.
  • Durability—Exterior walls, window frames, soffit, and trim that will not rot, peel, or warp can contribute to achieving points for Quality Management of Durability requirements for LEED H. Unlike wood, vinyl siding, polymer siding, and trim do not absorb water and are not subject to insect damage; they do not pit, rust, or corrode, and they never need painting. Most of our vinyl and polymer siding is warranted for the lifetime of the original owner, with the warranty transferable to a new homeowner for as much as 50 years from the date of installation. Vinyl siding, polymer siding, and PVC trim require less maintenance than wood and fiber cement.
