This list surveys many of the primary categories of building materials where PVC is commonly used and is organized by the CSI numbering system commonly used in commercial building specifications. While there are products for all building types represented here, the emphasis is on  materials suitable for commercial/institutional buildings. It is intended to provide a representative sampling of products and materials that do not contain PVC and are commercially available for a variety of applications. It is not intended to be comprehensive. In a rapidly changing market, the completeness and accuracy of this information cannot be guaranteed.

Inclusion on this list does not imply endorsement of any product or manufacturer, nor any warranty of the appropriateness of listed products for a particular application.

This list surveys many of the primary categories of building materials where PVC is commonly used and is organized by the CSI numbering system commonly used in commercial building specifications. While there are products for all building types represented here, the emphasis is on  materials suitable for commercial/institutional buildings. It is intended to provide a representative sampling of products and materials that do not contain PVC and are commercially available for a variety of applications. It is not intended to be comprehensive. In a rapidly changing market, the completeness and accuracy of this information cannot be guaranteed.

Inclusion on this list does not imply endorsement of any product or manufacturer, nor any warranty of the appropriateness of listed products for a particular application.
