Responses to Substitution Requests:

Vapor Barrier Substitution Request

The Government rejects this substitution request as it is not one of the listed manufacturers. It does have water resistance rating (below), which would make it a weather barrier, but it does not have the

ICC ratings as required by spec:

ICC-ES AC38 - Acceptance Criteria for Water-Resistive Barriers; 2016.

ICC-ES AC212 - Acceptance Criteria for Water-Resistive Coatings Used as Water-Resistive Barriers over Exterior Sheathing; 2015.

Resinous Flooring Substitution Request

The Government rejects the flooring substitution request as the information provided did not contain any information needed to be consistent with the performance specification
