Each Twinsert model is created by bridging any two of EMSEAL’s standard interior joint systems.
The bridging element is usually made of custom-configured aluminum.
The bridging element can become part of the finished, visible and trafficked surface of the joint or, like a “pan” joint, it can be recessed to support any floor material—tile, terrazzo, stone, etc.—being used elsewhere on the floor.
In contrast to “pan” joints, however, the bridging element can be configured to handle heavy loads that often lead to cracking of infill materials in lighter-duty systems (see Twinsert in action at Washington DC Convention Center).
Theoretically, Twinsert can be configured to handle ANY joint size. As long as a bridging material suitable to the loads expected can be secured to the selected standard joint system, this bridging material can be made to span joints as large as 24″.
The movement capability of any Twinsert configuration is equal to 2-times that of the standard model from which it is configured.
Floor-to-Wall versions of Twinsert can be configured in accordance with the floor-to-wall options available with the standard joint system selected as the flanking system–consult the product page for the specific system.
As with loading capacity and floor-to-wall options, leg heights are driven from those available in the standard joint system selected as the flanking system.
This option also allows for using DIFFERENT leg heights on either side of the bridging element. You might choose this option if there is a floor height differential across the joint.
FS 110 Twinsert with Aluminum Traffic Plate
In this example, twin FS 110/45, heavy-duty, aircraft-aluminum joints have been connected with a 1/2″ (12mm) aluminum bridging plate.
The width of the plate has been custom made to allow the bridging of an 8-inch wide expansion joint gap.
The thickness of the plate was calculated to handle forklift and vehicle loads required by the client–the Washington DC Convention Center (click herefor a project profile and to see the installed Twinsert).
In this particular application, the Twinsert was installed into a recess (blockout) on each side of the joint gap and installed proud of the surrounding concrete by the thickness of the adjacent carpet. As a result, the Twinsert system sits flush with the finished walking and traffic surface.
