Air-vapor barrier continuity device

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT FIGS.
1, 2 and 3 of the drawings illustrate a preferred embodiment of the invention.
FIG.
1 shows a front view of an air-vapour barrier continuity device 5 and FIGS.
2 and 3 show the plan and side views, respectively.
FIGS.
2 and 3 do not indicate a specific length of the continuity device; it may be manufactured in a variety of lengths as desired, for example, 10 foot sections which may then be cut to the appropriate length for any specific application.
As illustrated, a flexible first generally rectangular longitudinal planar member 10 angularly connects at a first back longitudinal edge 50 thereof to a second generally rectangular longitudinal planar member 20 at an angle greater than 90.
degree.
.
The greater-than-90.
degree.
angular connection provides a close-fitting biased contact of the first member to the wall stud when the continuity device 5 is installed.
The connection of the first member 10 to the second member 20 is along a longitudinal line 40 of the second member 20, the longitudinal line 40 being coincident with the second back longitudinal edge of the second member 20 in the illustrated embodiment.
The preferred air-vapour barrier continuity device is integrally formed as a flexible generally rectangular longitudinal polymeric (e.
g.
polyethylene) sheet bent along a longitudinal line thereof such that one side forms the first member 10 and the other side forms the second member 20.
The angle of the bend is greater than 90.
degree.
and is preferably 100.
degree.
as shown in FIG.
3.
The method of manufacture of the illustrated continuity device 5 is according to standard profile extrusion methods of making such polymeric piece items.
The continuity device 5 is installed during the construction (or reconstruction) of a wall before the air-vapour barrier sheet 80 and interior wall cladding 70 are installed (but after the exterior wall 170, the door or window 150, the wall studs 110, the rough sill 115 and/or the insulation 180 have been installed)
