Standard Specification for Flexible, Low Permeance Vapor Retarders for Thermal Insulation
STANDARD published on 1.3.2023
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers vapor retarders for thermal insulation, specifically, flexible materials with permeance and surface burning characteristics. Vapor retarders are classified based on vapor retardance and strength properties: Types I, II, III, IV, V, and VI. The following test methods shall be performed: water vapor permeance; surface burning characteristics; tensile strength; dimensional stability; fungi resistance; thermal integrity of flexible water vapor retarders; burst strength of vapor retarders; permanence of flame retardancy; and elevated temperature and humidity resistance of vapor retarders for insulation.
