25V

Primary seal in masonry where black reveal or shadow-line effect is desired

An above-grade, wall expansion joint, 25V is a long-term, economical, high-performance seal for expansion and control joints in concrete, brick, stone, etc. where a black reveal or shadow-line effect is desired or where installed in concealed conditions.

25V is comprised of permanently-elastic, high-density, open-cell polyurethane foam, impregnated with a water-based, acrylic-stabilized, asphaltic emulsion.

Supplied precompressed to less than the nominal joint gap, after being released from its packaging, 25V expands to seal the joint gap under its own internal backpressure.

Used extensively for sealing vertical abutment joints between buildings, brick and CMU control joints, joints in tilt-up panels, etc.
Anti-vibration and acoustic seal

Composition

Permanently elastic, high-density, open-cell polyurethane foam, impregnated with a water-based, acrylic-stabilized, asphaltic emulsion.

Design Considerations

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.

Maintenance

As with any construction product, the useful life of the material can be maximized with routine inspection and repair if required.
Occasional 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.
