From: National Research Council Canada
This document provides a summary of the minimum requirements imposed by the Canadian Construction Materials Centre (CCMC) for all evaluations based on the below criteria document. Additional requirements may be imposed by the CCMC when necessary for a particular evaluation, and are detailed in the individual evaluation.
Criteria document
| Number | CAN/CGSB-41.24-95 |
| Title | Rigid Vinyl Siding, Soffits and Fascia |
| Document | Standard |
| Publisher | Canadian General Standards Board |
Scope
These evaluations apply to vinyl siding as a flexible material used for exterior wall cladding of buildings. This standard applies to extruded sections produced from rigid compound of polyvinyl chloride intended as siding, soffits and fascia. Its wide range of characteristics includes good durability, light weight and minimal maintenance. It is available in a variety of profiles, colours and surface textures.

Installation requirements
The CCMC requires that evaluation holders provide instructions for the installation of the product(s) that:
- do not contravene the National Building Code of Canada, or any provincial or territorial building codes; and
- meet the requirements of CCMC minimum documentation requirements.
Manufacturing requirements
The CCMC requires that evaluation holders, at a minimum, demonstrate that the associated production process:
- is operated under a documented quality system; and
- meets the minimum requirements of the CCMC minimum documentation requirements.
Labelling requirements
The CCMC requires that evaluation holders ensure that product labels:
- reference the associated CCMC number or mark; and
- meet the requirements of CCMC minimum documentation requirements.
The vinyl siding is identified on the packaging with the following information:
- manufacturer’s name or logo;
- product’s tradename(s);
- colour of siding; and
- quantity (expressed in terms of effective coverage).
