Beschreibung
Zusammenfassung:	According to an aspect of the present invention there is provided a cavity barrier (1) for installation in a cavity (8), between first and second opposed walls (4, 6) of a building construction (2), so as to surround an opening (7) that extends through the first and second walls (4, 6) for a conduit (9) of the building construction (2). The cavity barrier (1) includes a unitary body portion comprising: a first surface (16) for location against the first wall (4) and an opposing second surface (18) for location against the second wall (6), a hole extending through a depth of the body portion, from the first surface (14) to the second surface (16), for receiving the conduit (9), an interior surface defined between the first and second opposed surfaces (14, 16) by the through-hole; an opposing exterior surface extending between the first and second opposed surfaces (14, 16); and a thickness extending around the through-hole, from the interior surface to the exterior surface, wherein a minimum thickness of the body portion is greater than or equal to 0.65 times the depth of the body portion.
