EIFS Termination At Soffit / Fascia Intersection
An overview of the EIFS Termination At Soffit / Fascia Intersection
In this post we are going to take a look at the EIFS Termination At Soffit / Fascia Intersection. This is a pretty simple process but in the field we come across a lot of soffit failure because this was done wrong. The wall in many cases has a moisture drainage system but when it comes down the wall and meets the soffit there is no where for the water to go but into the soffit. If this simple procedure is followed the moisture can escape and there will be no damage. The bottom corner where the fascia and the soffit meets is treated with a moisture barrier. The corner is wrapped with grid tape and Backstop NT Textured is applied over the tape. It should be noted her that the substrate would already have the moisture barrier applied to it (for more info on applying the moisture barrier take a look at the post ….) The bottom edge of the fascia where it meets the soffit is where a drainage strip will be adhered to the substrate, and when installing the foam it will be notched out for the drainage strip. The foam applied on the fascia will come down past the substrate of the soffit the thickness of the foam on the soffit. The fascia will be back wrapped before the foam is applied. The soffit side will have the foam applied about 3/4″ away from the foam that came down on the fascia creating an expansion joint for the moisture to escape. The soffit foam will be back wrapped as well. The most important part about this process is to take time when pulling the back wrap on the drainage strip side as it is very easy to fill the drainage strip with excess EIFS cement material and render the drainage strip useless.
