EIFS Window Header Specification

An overview of the EIFS Window Header Specification

In this post we will take a look at the EIFS Window Header Specification.┬áTo properly address the window header when using EIFS a weep track needs to be installed at the head of the window. Note: the window rough opening first needs to be treated with the moisture barrier (refer to the post … for further details on applying the liquid moisture barrier to a rough opening). A metal window flashing is installed over the window head. The metal flashing is attached to the substrate and down over the window. The metal flashing should go up the substrate about 4″ and down over the window about a 1/2″. The EIFS approved weep track with drip edge is installed over the metal flashing. The weep track is installed about 3/4″ above the bottom inside corner of the metal flashing. This leaves a nice 3/4″ caulk joint between the metal flashing and the weep track. A rod of closed cell backer rod is placed in the 3/4″ joint between the metal and the track, and a bead of EIFS approved caulk (for more info on approved EIFS sealants, see the post EIFS Caulking and Sealants) is applied over the backer rod. The key with the caulk is not to allow it to cover the holes in the weep track.EIFS Window Header Specifications
