Hal-Tex 30 Minute Building Paper is a heavy kraft paper which has been saturated with asphalt. This grade D building paper sheds water and restricts moisture from penetrating. However, it will allow the passage of water vapor, thus permitting wood to "breathe". This product is guaranteed to exceed 30 minutes of water resistance when tested per U.S. standard UUB-790a. Hal-Tex 30 Minute Building Paper can be used on outside walls of wood frame buildings, under the external finish, as a secondary protective barrier against entry of wind and moisture. It can be applied beneath wood siding, stucco, brick, aluminum, vinyl, or any other type of siding. It can also be applied under roofing shingles to prevent wind-blown moisture from reaching wood roof decking.
