Watertight Expansion Joints and Construction Sealants by EMSEAL

EMSEAL Expansion Joint Patents Confirmed Through Reexamination, New Patents Awarded, Others Pending

In its ongoing recognition of the company's innovations in the building product arena, the United States Patent and Trademark Office awarded US Patent 9,739,050. This patent covers EMSEAL's RoofJoint and RoofJoint Closure assembly--a first of its kind system designed to specifically address the transition from roof expansion joints to wall expansion joints.

Something New From EMSEAL Update January 2, 2018: On December 26, 2017 the United States Patent and Trademark Office, in its ongoing recognition of the company’s innovations, awarded US Patent 9,850,662 that further covers EMSEAL’s RoofJoint and BG System extrusions.

Update August 22, 2017: In its ongoing recognition of the company’s innovations, the United States Patent and Trademark Office awarded US Patent 9,739,050. This patent covers EMSEAL’s RoofJoint and RoofJoint Closure assembly–a first of its kind system designed to specifically address the transition from roof expansion joints to wall expansion joints.

Update June 27, 2017: Three more patents issued to EMSEAL in the past two weeks. Two of these cover our fire-rated, seismic, watertight joint systems in the SJS-FR product line. Patents 9,689,157 and 9,689,158 were awarded on June 27th and 9,677,266 for a movement-compensating cover plate anchor issued on June 13th.

Update June 6, 2017: The USPTO granted another patent extending further protection and recognition to EMSEAL’s fire rated all-in-one Emshield systems. EMSEAL’s 9,670,666 patent can be viewed on the USPTO site.

These new patents add further recognition of EMSEAL’s innovation in fire-rated and building expansion joint systems and reaffirms EMSEAL’s rights to exclusively manufacture and license the technology.

Additionally, despite efforts of others to challenge EMSEAL’s innovations in expansion joint technology, EMSEAL is proud that the United States Patent and Trademark Office has confirmed our previously patented innovations and continues to award new patent protection for our breakthrough fire and water resistant expansion joint systems. EMSEAL is doubly proud to have had its seismic expansion joint system patent reexamined and reconfirmed twice and to have our roof and below-grade expansion joint technology additionally recognized through patent awards.

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.
