Continuity of seal and continuity of thermal insulation throughout changes in plane and direction are hallmarks of COLORSEAL
Primary seal in most any substrate.
For vertical-plane joint-gaps from 12mm to 200mm.
Total 50% movement capability (±25% of nominal supplied size).
Twelve standard colours
Non-invasive anchoring, primary and secondary seal in one step, thermally insulating, acoustic dampening.
COLORSEAL is ideally suited to curtainwall and metal cladding systems, as well as concrete, brick, stone, etc.
COLORSEAL combines a factory-applied and cured silicone bellows with a microsphere-modified acrylic-impregnated expanding foam sealant backing.
Why silicone? Polyurethane sealant options have been proved to suffer dramatic modulus and other physical properties changes at low temperature and over time. The silicone used on COLORSEAL remains pliant, UV stable and watertight over time and temperature gradient.
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.
Unique among options for large joint-gap sealing, COLORSEAL and SEISMIC COLORSEAL can be positively secured at inside corners without invasive anchors. In addition the products' ability to maintain watertightness while handling curves and direction changes further sets it apart from rubber-and-rail strip seals
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 acrylic-impregnated cellular foam combined in some sizes with laminations of closed-cell foam. The impregnated foam contains no wax or asphalt compounds.
Puncturing of silicone facing does not affect sealant system performance.
Back pressure maintains seal and ensures that silicone bellows is never under tension from the effects of joint movement.
COLORSEAL has an R-value of approximately 3.28 per inch of depth which imparts thermal insulation at structural joint-gaps where thermal loss through strip-seals is often significant.
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.
See SEISMIC COLORSEAL, for high-movement and large joint sealing.
Standard sizes from 12mm to 200mm.
Sizes up to 20 mm have single convex facing.
Sizes from 25 mm and bigger have multiple bellows coating
100% free of wax or asphalt compounds (Why does this matter?)
