ASTM E3069-2019 实心砌体墙保温性与潮湿性评定及修复指南 Standard Guide for Evaluation and Rehabilitation of Mass Masonry Walls for Changes to Thermal and Moisture Properties of the Wall

1.1 This guide addresses the evaluation of existing mass masonry walls for the potential addition of interior insulation and continuous air barrier or vapor retarder or other changes to the thermal and moisture management properties of the wall.

1.2 This guide describes methods for evaluating moisture accumulation related problems specific to mass masonry walls. This guide does not apply to walls that include provisions to manage bulk water through internal drainage, flashings, or other measures other than the moisture storage capacity of the wall.

1.3 This guide describes analysis, design, and specification of materials with the required thermal, air, and vapor resistance to improve the energy performance of an existing mass masonry wall, but that would not create problematic conditions to the masonry units or within the masonry wall or interior of the building.

1.4 This guide applies to walls of masonry construction meeting the requirements of a “mass masonry wall” as defined herein. This guide does not apply to masonry walls that, by design, are intended to manage water as a barrier wall system or drainage wall system.

1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
