Membrane Interface for Building Apertures

摘要

An expanding seal for preventing water and air intrusion in gaps formed between aperture-engaged components of a wall which are surrounded by stucco or the like is provided. The device is configured to prevent moisture ingress between formed gaps created as stucco surfaces expand and contract over time which can exacerbate gaps. A first side of the body of the device engages the fixture while the opposing side is adapted for an embedded engagement with cured stucco whereby intrusion into gaps is prevented by elastic expansion and contraction of the seal.

主权项

1. A sealing apparatus for gaps between fixtures mounted in surrounding cementitious material, comprising:
an elongated body formed of substantially elastic material; said body having a first side configured for an adhesive engagement with a fixture positioned in a wall to be surrounded by stucco; said body having a second side edge, opposite said first side edge; means for anchoring said second side edge, into a layer of said stucco subsequently applied to said wall surrounding said fixture; said anchoring of said body on said second side edge and said adhesive engagement along said first side edge, and a stretching of said body therebetween, defining an elastic seal over said gap which maintains said seal even during gap enlargements caused by differing expansion rates of said stucco and said fixture during temperature differentials.
