ASTM E2925-14 - 1.6.2014
 
1. Scope

1.1 This specification is applicable to manufactured polymeric materials used to provide a rainscreen function, a means for the drainage of liquid moisture and the ventilation of vapor moisture that enters an above-grade exterior wall assembly. Rainscreen materials that comply with this specification are intended to be used behind exterior cladding products and intended to cover one hundred percent (100 %) of the wall area that is designed to provide a rainscreen function to resist water infiltration.

1.2 This specification addresses the following types of rainscreen materials:

1.2.1 Type A—entangled mesh materials.

1.2.2 Type B—formed/textured sheet material.

1.2.3 Type C—formed battens.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
