Towards development of a performance standard for assessing the effectiveness of wall-window interface details to manage rainwater intrusion

摘要

This paper presents a proposed laboratory test protocol for assessing the effectiveness of wall-window interface details with regard to management of rainwater, and provides a rationale for a performance-based approach to the evaluation method. An overview of the test approach is provided and details of the test apparatus and test specimen are given, including information on implementation of the test method. Examples of testing performed according to the proposed protocol are provided. Finally additional tests for evaluating the performance of installation details are suggested. The additional tests are for field evaluation of installation details, and for laboratory evaluation of installation details with regard to the risk of condensation along window frames.
