摘要：An end cap for an I - joist, to limit air leakage where the joist is mortared into a wall, has a face 15 from which two protrusions 11 extend and define a space 9 therebetween which receives the web of the I - joist. Surfaces 15, 17 may be present which overlie the ends of the flanges of the joist. In other embodiments, surfaces 15, 17 are absent (Fig 5) , the space 9 diverges toward surface 15 and members 11 are chamfered at their outer edges (Fig 7), flanges to overlie the wall are added to members 11 (Fig 11), members 11 are replaced by J-section plates (Fig 14), the body is U- shaped (Fig 16), the body is a plate with projecting "clips" to contact the flanges of the beam (Fig 17) or is formed as two separate blocks (Fig 20).
