COLORSEAL is a
secondary seal ideally suited to curtainwall and metal cladding
systems, as well as concrete, brick, stone, precast, EIFS, etc.
Microsphere-modified-acrylic-impregnated foam sealant,
factory pre-coated with high-grade silicone. Watertight,
handling, UV stable, non-staining, low temperature
flexible, high-temperature stable.
COLORSEAL combines a factory-applied and cured silicone
bellows with a microsphere-modified acrylic-impregnated expanding foam
COLORSEAL features EMSEAL’s microsphere-modified acrylic
impregnation infused into a cellular foam base material and is coated with a
high-grade silicone coating that has been tested for durability under
continuous UV, water, and air pressure differential exposures typically
experienced by modern structures.
Continuity of seal and continuity of
thermal insulation throughout changes in plane and direction are
hallmarks of COLORSEAL.
Unique among options for large joint-gap sealing, COLORSEAL and
COLORSEAL can be positively secured at inside corners without
In addition the products' ability to maintain
handling curves and direction changes further sets
it apart from rubber-and-rail strip seals.
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.
Puncturing of silicone facing does not affect sealant
pressure maintains the seal and ensures that the silicone bellows is
never under tension from the effects of joint movement.
This means that neither the bellows nor the corner bead are in tension
during joint opening movement.
COLORSEAL an aesthetically versatile option for joints from
up to 8" (200mm).
R-value--An R-value of approximately 1.8 per inch of depth 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
compression set typical in closed-cell foams.
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.
with 100% movement
for high-movement and large joint sealing is also available.
COLORSEAL-DS (Double sided) is available for shallow-substrates, or where sealing
both the inside and outside expansion joint in a single step is desired.
(Pick Resistant)--Now also available for detention and security
applications with pick-resistant polyurethane bellows. Colors available
are Tru-White and Limestone. More information

2.5 psi backpressure from the foam.
Transitions and Terminations:
(US Patent 9,200,437 Patent Pending)
U-90's are factory-made transition pieces that ensure continuity-of-seal where expansion joints change plane or direction.
Custom-90's (patent pending), coated on just the weather-facing faces, are also available when field conditions and measurements are known up front.
COLORSEAL is manufactured in straight-run sticks which can be joined in the field to EMSEAL’s patented and patent-pending "Universal-90" transitions.
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. Universal-90 transition are symmetrically coated on both faces allowing 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.

Flipped-Over as Downturn Transition
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. The combination of the
active backpressure and the pressure-sensitive nature of the acrylic
impregnation ensures the attachment of the foam to the other substrate.
The injection and tooling
of a corner bead of silicone between the cured bellows and substrate
completes the installation.
