COLORSEAL

COLORSEAL is a precompressed hybrid--primary plus secondary seal with --with 50%  movement capability (+25%, -25% of nominal material size).

COLORSEAL is ideally suited to curtainwall and metal cladding systems, as well as concrete, brick, stone, precast, etc.

COLORSEAL combines a factory-applied and cured silicone bellows with a microsphere-modified acrylic-impregnated expanding foam sealant backing.

The bellows holds the key to COLORSEAL's unique performance.  Alternatives comprised of a pre-cured block of silicone over a un-impregnated foam backing must still be caulked to the substrate with large applications of liquid sealant.

COLORSEAL features non-invasive anchoring which means you are not drilling and screwing into sensitive substrates. This eliminates the risk of spalls and enables installation into inside corners that are impossible to seal with screw-anchored strip-seals.

The expanding foam backing is a microsphere-fortified, acrylic-impregnated cellular foam.  The impregnated foam contains no wax or asphalt compounds.

Puncturing of silicone facing does not affect sealant system performance.

Back pressure maintains the seal and ensures that the silicone bellows is never under tension from the effects of joint movement.

COLORSEAL has an R-value of approximately 1.8 per inch of depth which imparts thermal insulation at structural joint-gaps where thermal loss through strip-seals is often significant (click here for more on r-values).

Unlike imitations that use closed-cell foam backings and that must be forced into compression in the field, COLORSEAL is supplied pre-compressed to smaller than the joint size.  This means that neither the bellows nor the corner bead, nor the foam backing are in tension either during the full extent of movement capability nor as a result of compression set typical in closed-cell foams.
 

This means that neither the bellows nor the corner bead are in tension during joint opening movement.

COLORSEAL has a mounting adhesive on one face.  After removal from its packaging, the material is inserted into the joint and adhered to one side. It then expands to fill the joint.

Standard sizes from 1/2" (12mm) to 8" (200mm).
Sizes up to 3/4" (20 mm) have single convex facing.
Sizes from 1" (25 mm) and bigger have multiple bellows coating.

Double-Sided also available--SEISMIC COLORSEAL-DS (Double sided) for shallow-substrate, or where sealing of the inside and outside expansion joint in a single step is desired.

*Sound Attenuation is also a feature of COLORSEAL. With a 2 1/2" standard depth product installed in one side of a STC 72 wall, COLORSEAL had a STC 56 rating and in an OITC 61 wall it had a 53 OITC rating. When installed from both sides of a STC 72 wall it received the maximum of STC 72 equaling the sound suppression of the wall and in an OITC 61 wall it received a OITC 60 rating.

Custom Colors:
If you're having a custom color formulated for your project which is not in the Dow-790 or Pecora 890NST palette of standard colors please contact EMSEAL to have us produce a matching color from another manufacturer or from silicone material shipped to us from that project.  Contact Us.

COLORSEAL is manufactured in straight-run sticks which can be joined in the field to EMSEAL’s patent-pending "Universal-90" transitions.

Universal-90 Upturn Transition

Universal-90 Flipped-Over as Downturn Transition

These factory-fabricated single-piece 90-degree units have a 12-inch long leg and a 6-inch vertical piece on each side of the elbow. The Universal-90 transition pieces are symmetrically coated on both faces.  This allows them to be installed as an inside corner or as an outside corner.

In addition to guaranteeing watertightness, EMSEAL’s "Universal-90's" allow for much faster and secure installation by eliminating field cutting or notching and bending, at angles.
