A: Yes you can use DriStud FRU38, FRU36 and RU24 as wall underlays.
DriStud FRU38, FRU36 and RU24 satisfy the requirements for E2 External Moisture and this is supported by the CodeMark certificates. Because the requirements for roof underlay exceed the requirements for wall underlay for compliance with E2 External Moisture in all respects it follows that all the DriStud roof underlays also comply with the requirements of E2 External Moisture when used as wall underlay.
