ATMOSPHERIC CARBON STORAGE IN CONSTRUCTION MATERIALS - PART 2.

Building materials, on the other hand, are designed to last for decades, some for centuries. PVC (polyvinyl chloride) pipes working underground to carry away waste water could feasibly last 1000 years or more, while those above ground might be expected to last 50 -100 years, possibly more. (Yes, I know, there have been premature plastic pipe failures.) Foam insulation should last the life of the building, which should be 100 years. PVC and plastic/wood composite decking material, which by the way is often made of recycled plastic, should last 50 years. Other materials made all or in part of plastic like windows, doors or plumbing fixtures might lose functionality or aesthetic appeal and be replaced long before the plastic material they are made of fails or decays.
