Emseal Seismic ColorSeal-DS: Curtainwall Expansion Joint

Emseal Seismic ColorSeal-DS is a curtainwall expansion joint, Emseal Seismic ColorSeal-DS is a multi-faced, silicone-coated, precompressed, primary seal in structural, high-movement, joints in virtually any substrate. It is ideal for  curtainwall and other shallow substrates where sealing or finishing of both sides of the structure is desired. A hydrophobic-acrylic-impregnated foam sealant, factory pre-coated with high-grade silicone, the product is watertight, odorless, clean handling, UV stable, non-staining, low temperature flexible, and high-temperature stable.

Seismic Colorseal-DS is a unique, highly innovative, customized variation of EMSEAL’s acclaimed Seismic Colorseal material. It ensures watertightness in vertical and horizontal structural, seismic, and abutment joints in walls of precast concrete, brick, curtain-wall, stone, and virtually any other substrate.

Seismic Colorseal-DS provides considerable sound attenuation as a joint filler in interior demising walls,  partitions or in sound studios, performance halls, broadcast booths, etc.  A concrete wall with an expansion joint through it can be restored to the virtually the same sound transmission coefficient as the solid wall without a joint.

  • Size switching accommodates joint gap variations

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.

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