The fire resistant, CE-marked, Emseal Colorseal system is used to seal joints in external facades and parapet walls, with up to 100% (+/-50%) joint movement capability and high insulation values.
Application
Typically, the Emseal Colorseal system is used to provide a watertight sealed movement joints in external facades and parapet walls for example, where it is especially suitable for wide and/or high movement joint sealing applications i.e. for joints from 12mm up to 200mm, with a joint movement capability up to 100% (+/- 50%). This means it is suitable for use as both single and double-sided joint sealing, in both primary and/or secondary joint sealing solutions, according to the structural design and exposure requirements.
The Emseal Colorseal system does not require any invasive and potentially damaging mechanical fixings, and provides highly durable watertight sealed joints for many different exposed situations on building facades and other structures.
Description
Emseal Colorseal-VHE is a fire resistant, 2 hour CE-marked, ETA-certified, double-sided silicone-faced movement joint which provides a watertight seal with 100% movement capability, plus high thermal insulation, UV stability, and colour coordination for both vertical and horizontal substrates. It performs these functions without invasive metal anchoring or complex field fabricated assemblies. In contrast to liquid-applied sealants, Emseal Colorseal-VHE-CE is free of tensile stresses at the substrate bond line. Colorseal-VHE provides a cost effective, long term watertight seal.
Colorseal-VHE combines a factory applied, low modulus silicone with an open cell polyurethane foam infused with a water-based, fire-retardant, acrylic dispersion. The coloured silicone facing is factory adhered to the infused foam on two sides at a width greater than the maximum anticipated joint extension, and is then cured.
When compressed, the silicone facing forms a bellows profile capable of accommodating +/-50% (total 100%) movement from the product’s nominal size. The bellows fold, and unfold during movement virtually free of tensile stresses.
Colorseal-VHE is supplied pre-compressed to slightly less than its nominal size for ease of installation. To install sticks, clean he substrate walls. Apply the supplied epoxy adhesive to the substrates. After removing packing materials insert the Colorseal-VHE into the joint. After the Colorseal-VHE has expanded to fill the joint space and is bonded to the substrates, a field-applied silicone corner bead ensures a watertight seal at the substrate interface.
Features and benefits:
- +/-50% Movement capability.
- Watertight seal.
- UV resistance.
- Traffic-grade silicone surface.
- Eliminates tensile stresses at bond line.
- Very fast and simple installation.
- No invasive anchoring.
- No complex field-fabricated assemblies.
- Available in industry-standard colours.
- Supplied pre-compressed to less than nominal joint size.
- Coated on two sides (for use in double-sided applications with opposing exposed surfaces).

Emseal Colorseal seals joints between precast façade panels at the Broadway Redevelopment In London
Emseal Colorseal VHS was used on Dixons Hotel at Tower Bridge in London, to seal the large, high potential movement capability, structural façade movement joints that also have variable widths, between the historic original building and its new extension
Emseal Colorseal celebrates 3 decades of successfully sealing wide expansion joints between the original building and its 10-story extension added back in 1992 at the Guggenheim Museum in NYC
