About This Item
ASTM C1397 is the ASTM standard for the application of Class PB Exterior Insulation and Finish Systems (EIFS) and EIFS with drainage. It provides a technical reference for how these exterior wall systems are installed and applied, helping support consistency in construction and product use. As a standards document, it is relevant to projects where EIFS performance, detailing, and installation quality all matter to long-term serviceability and compliance.
Purpose of ASTM C1397
The purpose of ASTM C1397 is to guide the application of Class PB EIFS and EIFS with drainage in a way that supports proper installation practices. The standard helps define a common technical framework for applying these exterior insulation and finish systems, which may be used to improve uniformity across projects. For manufacturers, contractors, specifiers, and inspectors, ASTM C1397 serves as a practical reference for aligning application work with recognized industry expectations.
Common use cases of ASTM C1397
This standard is commonly used when specifying, installing, or reviewing exterior wall systems that include Class PB EIFS or EIFS with drainage. It is especially useful on building envelope projects where the application method affects finish quality, drainage detailing, and overall system performance. ASTM C1397 may also be used during procurement, field inspection, and quality control to help confirm that the chosen EIFS installation approach follows a recognized ASTM standard.
Why ASTM C1397 matters
ASTM C1397 matters because consistent application practices can reduce installation risk and help support expected system performance. When EIFS and EIFS with drainage are installed according to a recognized standard, project teams have a clearer basis for compliance, evaluation, and communication. Using ASTM C1397 can also help support quality control and reduce misunderstandings between design, procurement, and field installation teams.
