Acceptance Criteria for Polypropylene Roof Underlayments AC 207 & Acceptance Criteria for Roof Underlayments for use in severe climate areas AC48. Tested in accordance with ICC-ES AC 48 and AC 207 criteria to meet UBC, IBC and IRC requirements for Roofing Underlayments.
*ASTM E 96 - Method B (wet cup method) typically gives a more realistic result for permeance than does the Method A (dry cut/desiccant) method.
| SlopeShield is not to be used as a temporary roof covering during the construction period. SlopeShield can sustain up to 4 months of UV exposure but is not intended to be the primary liquid water hold out barrier. Temporary protection measures such as tarps must be used when rain, snow/ice or storm events exist or are anticipated. |
