EMSEAL’s inventions have profoundly changed the way buildings are waterproofed and fire rated. The benefits extend to architects and engineers, general contractors, subcontractors, distributors and sales reps and ultimately to property owners.
Architects and engineers can specify with the confidence borne of validation by extensive UL 2079 testing in walls and floors and benefit from being able to simplify design by eliminating under-slab fire barriers. Under-slab fire barriers often become interrupted by columns, intersecting walls and other obstructions. This interrupts continuity in the fire barrier. Installed entirely from easily accessible floor and wall locations, the Emshield products ensure continuity and proper fire compartmentation. Because the Emshield products perform multiple tasks with a single product, opportunities for LEED credit are possible through reduction of materials, improved insulation values minimizing thermal breaks, and acoustic environmental control. The Emshield products can be installed alone or beneath any cover plate or expansion joint cover at the designers’ preference.
For general contractors, construction managers, and subcontractors the Emshield products improve productivity, remove the need for below-slab access, remove coordination concerns with electrical, mechanical, plumbing and HVAC trades, and can consequently shorten project completion schedules.
For EMSEAL distributors and sales representatives, EMSEAL’s product line knits together their roof membrane, air barrier, deck coating and below-grade waterproofing product offerings allowing them to provide, to architects and contractors alike, fully integrated building envelope waterproofing and fire proofing solutions.
The property owner benefits from a safer, lower maintenance, high performance building. The durability of EMSEAL ensures that lowest total cost of ownership expansion joints and can dramatically reduce costly occupancy and revenue disruption and tenant complaints.
Emseal continues to innovate and anticipates further grants of US Patents in both its fire-rated, non-fire-rated, factory-fabricated transition, roof and below grade expansion joints and other technologies.
