Emseal Seismic Colorseal: High Movement Wall Joints

Emseal Seismic Colorseal: High Movement Wall Joints

Emseal Seismic Colorseal is a wall expansion joint, Emseal Seismic Colorseal (Colorseal*) is a silicone-coated, precompressed primary seal for high-movement wall joints. Seismic Colorseal ensures watertightness in vertical-plane structural, seismic, and abutment joints in virtually any substrate. Questions? Contact Us.

Continuity of seal and continuity of thermal insulation throughout changes in plane and direction are hallmarks of Seismic Colorseal. The product’s ability to maintain watertightness when installed at inside corners, and while handling curves and direction changes further sets it apart from rubber-and-rail strip seals. Seismic Colorseal is positively secured without invasive anchors while color-switching makes the product aesthetically versatile.

Seismic Colorseal was developed to restore the function of the building envelope where it is breached by the location of a movement joint. As a result, the performance tests required to certify curtainwall and other building envelope systems are the basis of performance of Seismic Colorseal as well. Seismic Colorseal has been tested to, and exceeds, the requirements of performance tests including: for Water Penetration: ASTM E-331; Wind Loading: ASTM E330; Air permeability: ASTM E283-04; Sound blocking: ASTM E90-09; R-Value: ASTM C518-04; Low-Emitting Material : CDPH/EHLB/Standard Method Version 1.2, 2017; as well as in-house Temperature Stability, Bleeding, Staining & Recovery testing to ensure performance under conditions modeling real life.

Watertight—the low tension silicone bellows is installed just back from the wall surface. This ensures watertightness is achieved at the face of the wall preventing water getting trapped against the substrates or within the joint cavity.

Non-Invasive Anchoring—there are no hard metal-to-substrate connections in the system. This includes embedded pins, anchors, screws, bolts or tracks, trays or rails that often damage sensitive substrates and act as a thermal bridge. Non-invasive anchoring means the system is locked to the joint faces by means of the 1) backpressure of the foam, 2) the injected silicone corner bead at the joint face to foam and silicone bellows interface.

Continuity of Seal—as in all EMSEAL expansion joint systems, continuity of seal through changes in plane and direction is an essential performance differentiator. Details for watertight, transitions using factory-fabricated Universal and Custom transitions pieces are available from EMSEAL. Seismic Colorseal Roof Closures are also available to ensure continuity of seal from wall joints to our RoofJoint roof expansion joint system.

Aesthetics & Versatility—26 standard colors, uniform bellows appearance, ability to handle variations in joint size are among other system features.
