Watertight, insulated, non-invasive, attractive--moving.
Skywalks at Hilton Hotel, Logan International Airport
sealed with SEISMIC
COLORSEAL by EMSEAL.
(New
construction 1998)
 |
Skybridges pose unique expansion joint sealing challenges.
The skybridge connector between the hotel and central parking at the Hilton at Boston's Logan International Airport is no exception. The material must look good, thermally insulate, handle substrate changes, maintain continuity of seal through plane and direction changes, and must do all of this while moving through extreme seasonal temperature cycles.

 |
Aesthetics: The appearance of the seal
making the intersection between the curtainwall and the masonry is critical to the
architect and owner. Selection of Gray from the standard 25-COLORS makes the seal appear an integral part of the skywalk curtainwall system
|

SEISMIC
COLORSEAL by EMSEAL uniquely handles all of the challenges posed by this application.
Non-invasive anchoring ensures that the metal framing of the skylight and other substrates is not violated. High wind resistance--Curtainwall systems are required to be tested to meet the ASTM performance tests E-293, E-331, and E-330. Sealants generally are not. To us it makes sense that the expansion joint sealant that will connect the curtainwall to the building should be independently certified to meet the same criteria. Consequently, we have tested SEISMIC COLORSEAL to meet or substantially exceed these same standards.
|
|
 |
Multiple changes in plane and direction are readily handled through field mitering and splicing. Using joining silicone supplied from the same batch used to manufacture the coating ensures continuity of seal throughout the expansion joint run. | |
 |
Thermal Insulation: Because skywalks
are suspended, expansion joints are particularly susceptible to allowing thermal loss.
SEISMIC COLORSEAL has an R-value of 2.15 per inch of depth giving this application
an R-rating of more than 8.5 at the joints.
SEISMIC
COLORSEAL is one of the hugely versatile COLORSEAL
family of cutting edge composite sealing technologies available from EMSEAL |
