Colorseal®/Seismic Colorseal-DS

Multi-faced, silicone-coated, precompressed, primary seal seals both sides of substrate

A curtainwall expansion joint, 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.

  • interior partitions
  • sound barrier

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 & Versatility26 standard colors, uniform bellows appearance, ability to handle variations in joint size are among other system features.

  • Produced by infusing a cellular foam base material with a hydrophobic, hydrophobic-acrylic impregnation, and coating the surfaces with a high-performance silicone to suit the application.
  • The external silicone facing is factory applied to the foam at a width greater than maximum joint extension and is cured before final compression.
  • Silicone application and curing takes place in a temperature and humidity-controlled factory environment. This ensures, in contrast to field applied liquid sealant and backer rod installations (‘caulk-and-backer rod‘), that no movement takes place during curing that can cause deformation or stresses in the sealant material.
  • The material is precompressed to less than the joint size for easy insertion.
  • When compressed, a bellows is created in the coating. As joint movement occurs the bellows simply folds and unfolds free of tension on the bond line, and virtually free of tensile stresses in the silicone material.
  • The material is supplied in 6.56 LF (2m) shrink-wrapped lengths (sticks). After removal from the shrink-wrap and hard board restraining packaging, it expands gradually.
  • The foam provides a resilient backing to the silicone coating, making the system capable of resisting air pressure differentials caused by building climate controls as well as by wind, hurricane and tornado events.
  • Substrates must be clean, parallel, plumb, have sufficient clear depth to receive the material specified, and be capable of resisting approx. 2.5 psi backpressure from the foam.

Universal-90’s
(US Patent 9,200,437; Patent Pending)

  • Universal-90’s (or U-90’s) are factory-made 90-degree transition pieces that ensure continuity-of-seal where expansion joints change plane.
  • Use of U-90’s eliminates the field work needed to make plane changes making overall installation fast and efficient.
  • Watertightness through the plane change is guaranteed–leaving nothing to chance in field-fabricating inside and outside transitions.
  • U-90 transitions are symmetrically coated on both faces allowing them to be installed as an inside corner or as an outside corner.
  • Straight-run sticks are joined in the field to the U-90’s.
  • U-90’s have a 12-inch (305mm) long leg and a 6-inch (152mm) vertical piece on each side of the elbow.

Custom-90’s
(Patent Pending)

  • Custom-90’s, are factory-fabricated inside and outside 90-degree transition pieces coated on just the weather-facing faces.
  • Custom-90’s are available when field conditions and measurements are known up front.
  • Custom-90’s are widely used in applications where numerous inside and outside 90-degree transitions are required. Consult EMSEAL.
  • As with any construction product, the useful life of the material can be maximized with routine inspection and repair if required.
  • Clearing of surface debris and inspection will reveal any damage to the product or adjacent substrates that might affect building performance.
  • EMSEAL precompressed sealants are easily repaired–requiring only damaged sections to be removed and reinstalled–not the entire length of the joint as is typical of extruded-seal systems.
  • Available for shipment internationally.
  • Prices are available from local distributors or representatives and/or directly from the manufacturer.
  • The product range is continually being updated, and accordingly EMSEAL® reserves the right to modify or withdraw any product without prior notice.
