WEATHERSEALS: JAMB SEALS

The following drawings show seals used at the top and sides of hinged windows or doors. For new work, it is always best to choose a weatherseal designed to seal to the face of the door. Flipperseals such as WS12, WS14, or WS15 are recommended for most applications because they offer the widest sealing range with minimal closing resistance. Tubeseals such as WS10 or WS11 can give excellent seals but require close tolerances and should not be used with warp-prone woods or sloppy hardware.

The preferred solution for retrofitting is to cut a groove with our WS98 Corner Grooving Machine and insert WS32 - WS36 tubeseals. Good alternatives are WS02 - WS06 which are caulked in place, or WS12 or WS14installed in a stop applied to the jamb.

The curved arrow in the following drawings shows the direction of motion of the window or door as it swings open.

WS12 in Rabbetted Jamb
WS12 IN RABBETED JAMB

Cut a 1/8" x 1/4" (3mm x 6mm) groove
in the center of any width rabbet.

WS14 IN RABBETED JAMB

Cut a 1/8" x 1/4" (3mm x 6mm) groove
in the center of a 1/2" (13mm) rabbet.

WS15 IN RABBETED JAMB

Cut a 1/8" x 1/4" (3mm x 6mm) groove
in the corner of a 1/2" (13mm) rabbet.

WS04 in rabbeted jamb

WS02, WS03, WS04, WS05, OR WS06 IN RABBETED JAMB

Measure the largest of gaps A and B to choose the proper
size and adhere with silicone caulk in the corner of rabbet.

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"

WS34 in rabbeted jamb

WS32, WS33, WS34, WS35, OR WS36 IN RABBETED JAMB

Measure the largest of gaps A and B to choose the proper size
and insert into a 45° groove cut with WS98 corner-grooving machine.

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"

WS 11 in rabbeted jamb
WS11 IN RABBETED JAMB

Cut a 1/8" x 1/4" (3mm x 6mm) groove
in the center of any width rabbet.

WS39 IN RABBETED JAMB

Cut a 1/8" x 3/8" (3mm x 10 mm) groove at a
5° angle in the corner of a 1/2" (13mm) rabbet
(the angle is optional, but it gives the best fit).

WS14 IN WS40 IN RABBETED JAMB

To prevent damage to grooves in jambs of doors receiving heavy
use, cut a 3/16" x 5/16" (5mm x 8mm) groove in the center
of a 1/2" (13mm) rabbet and then glue in a WS40 channel.

WS16 IN RABBETED JAMB

Cut a 1/8" x 1/4" (3mm x 6mm) groove in the corner of the
rabbeted jamb (not recommended for jambs thinner than 1-1/4").

WS24 in European sash

WS24 IN EUROPEAN SASH

Cut a 5mm" x 8mm" (3/16" x 5/16") groove in the corner of the
rabbeted jamb. Note that the shoulder on which the seal rests
must be 12mm wide. WS24 is installed with a special miter
tool that does not cut completely through the seal at the corner,
thereby maintaining a continuouse perimeter seal. This
drawing also shows WS10 installed in the jamb as a secondary
seal, GG61 as the exterior glazing gasket, GG23 as the interior
glazing gasket, and a eurogroove provided for hardware installation.

WS10 IN STOP MOLDING

Cut a 1/8" x 1/4" (3mm x 6mm) groove in the center
of any molding that is at least 3/8" thick. Caulk
between the stop and jamb to stop air leakage.

WS12 IN STOP MOLDING

Cut a 1/8" x 1/4" (3mm x 6mm) groove in the
center of any molding that is at least 3/8" thick.
Caulk between the stop and jamb to stop air leakage.

WS14 IN STOP MOLDING

(3mm x 6mm) groove in the center of any 1/2" (13mm)
molding. Note that one lip of WS14 stops air flowing behind
the stop and another protects the edge of the stop.

WS15 IN STOP MOLDING

Cut a 1/8" x 1/4" (3mm x 6mm) rabbet in the side
of any 1/2" (13mm) molding. Note that the foot of
WS15 stops air flowing behind the stop.

WS20 in WS50 on jamb
WS20 IN WS50 ON RABBETED JAMB

Attach WS50 channel to the jamb with screws driven in
with a WS94 setting tool. The channel must be mounted
within 3/16" (5mm) of the door or window.

WS12 in WS40 on jamb
WS12 IN WS42 ON RABBETED JAMB

Snap WS42 channel onto delrin clips
screwed into the jamb. Drill pilot holes for
the clips 5/8" (16mm) from the door or window.
