Skywalks at Hilton Hotel, Logan International Airport sealed with SEISMIC COLORSEAL by EMSEAL.

		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 11-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.

		Multiple changes in plane and direction are readily handled through field mitering and splicing using liquid silicone supplied from the same batch used to manufacture the coating.

		Thermal Insulation: Because skywalks are suspended, expansion joints are particularly susceptible to allowing thermal loss. SEISMIC COLORSEAL has an R-rating of 3.28 per inch of depth giving this application an R-rating of more than 13 at the joints. SEISMIC COLORSEAL is one of the hugely versatile COLORSEAL family of cutting edge composite sealing technologies available from EMSEAL --More on SEISMIC COLORSEAL--
