Master 3-part specification for rubberized asphalt, flexible, self-adhering flashings for use in various exterior assemblies to provide an air and water seal.
They are useful in providing continuity between dissimilar materials such as weather barriers and window assemblies and under wall copings.
Some flexible flashing materials, particularly rubberized asphalt, are not compatible with certain weather barriers and need to be carefully coordinated.
The advantage of rubberized asphalt flashings is their ability to self-seal around fastener penetrations and at seams as temperatures rise.
Rubberized asphalt flashings used under sheet metal are subjected to extremely high temperatures and can reach flowable consistency. A high-temperature version is available from many manufacturers.
