WEATHERSEALS: CENTER SEALS

The following drawings show seals at the meeting point of two hinged doors. The curved arrow show the direction of the door or window as it opens. For best results, choose a surface seal that will be in the same plane as the jamb seals, rather than an edge seal that is offset from the jamb seals and can allow air entry at the top and bottom.

WS12 in T astragal
WS12 IN T-ASTRAGAL

Cut a 1/8" x 1/4" (3mm x 6mm) groove into a
T-astragal. The astragal must be thick enough
to resist splitting under the impact of closing
and must be rabbeted to allow the proper gap.
WS10, WS11, WS14, or WS15 could be used
in a similar manner with appropriate gaps.

WS34 in T-astragal
WS32,33,34,35,36 IN T-ASTRAGAL

Cut a 45° groove cut with a WS98 grooving
machine. Measure the largest of gaps A and B
to select the proper size seal:

Weatherseal	Gap Range
WS32	0 - 1/8"
WS33	1/16" - 3/16"
WS34	1/8" - 1/4"
WS35	3/16" - 5/16"
WS36	1/4" - 3/8"

WS04 on T-astragal
WS02, WS03, WS04, WS05, OR WS06 ON T-ASTRAGAL

Adhere the tubeseal in the corner of the astragal with
a fillet of silicone caulk. Measure the largest of gaps
A and B to select the proper size seal:

Weatherseal	Gap Range
WS02	0 - 1/8"
WS03	1/16" - 3/16"
WS04	1/8" - 1/4"
WS05	1-4" - 5/16"
WS06	5/16" - 3/8"

WS16 IN SURFACE ASTRAGAL

Cut a 1/8" x 1/4" (3mm x 6mm) groove into the
corner of a rabbeted molding and mount it to the
surface of one of the windows or doors.

WS16 IN RABBETED OVERLAP

Cut a 1/8" x 1/4" (3mm x 6mm) groove into the
corner of the rabbet on one of the windows or
doors. This approach will not work with most
standard door hardware systems because the
locking mechanism must be installed into a
square edge.

WS20 IN WS50 ON ASTRAGAL

Attach a WS50 channel to any 3/8" – 1/2"
(10mm – 13mm) thick wood molding using
screw-nails (included) and a WS94 setting tool
(order separately). Screw the molding to one
of the windows or doors and insert the WS20.

WS17 in WS40 adjustable
ADJUSTABLE VERSION OF WS17 IN WS40

Cut a 3/16" x 5/8" (5mm x 16mm) groove in the
edge of one door or window. WS92 screws in the
base of the groove are used to adjust the seal by
limiting the depth of penetration of the channel.
WS62 or WS78 brushes can be used instead of
WS17. This technique can be used for two-way
swinging doors without jambs: use the same
seal on all four sides of each door.
