It supersedes the first edition, published in 1988 under the title Asphalt-Coated Glass-Base Sheet. It is one of a series of CSA Standards on bituminous roofing materials.<\/p>\n<p><\/p>\n<p>This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.<\/p>\n<p><\/p>\n<p><strong>Scope<\/strong><\/p>\n<p><\/p>\n<p>1.1<\/p>\n<p>This Standard covers three types of asphalt-coated glass-base sheets (asphalt-impregnated and -coated glass-roll roofing) surfaced with insoluble inorganic mineral matter:<\/p>\n<p><\/p>\n<p>(a) Type I: a lightweight base sheet intended primarily for use as an underlayment for shingles.<\/p>\n<p><\/p>\n<p>(b) Type II: a standard-weight roofing base sheet intended for use as the first ply in a roofing membrane over insulation.<\/p>\n<p><\/p>\n<p>(c) Type III: a venting base sheet surfaced with fine mineral matter on top and mineral granules on the bottom. This type is used in built-up roofing systems as a first ply to relieve pressure through lateral vapour movement.<\/p>\n<p><\/p>\n<p>Type III felt can be unperforated or, if used for spot mopping, contain perforations of a size specified in Table 1.<\/p>\n<p><\/p>\n<p>1.2<\/p>\n<p>In CSA Standards, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the standard.<\/p>\n<p><\/p>\n<p>Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.<\/p>\n<p><\/p>\n<p>Notes to tables and figures are considered part of the table or figure and may be written as requirements. Legends to equations and figures are considered requirements.<\/p>\n<p><\/p>\n<p>1.3<\/p>\n<p>The values given in SI (metric) units are the standard.
