Unelko Corporation, developers of the world-famous Invisible Shield Glass Coatings, is pleased to announce they have made significant advances in the Glass and Building Maintenance category, helping to protect thousands of homes, offices and glass buildings worldwide with their high-performance glass coating.    

As homeowners and commercial building owners know quite well, it can be very expensive to have their residences or commercial building’s glass cleaned every month or quarter—only to need to get it cleaned again shortly thereafter. 

In addition, many window cleaning companies have resorted to using razor blades, abrasive pads and brushes to remove stains, which further scratches and degrades the glass, and dramatically reduces its clarity and appearance. 

Thanks to Invisible Shield PRO 15 from Unelko, frequent cleanings that can damage glass are now a thing of the past. 

The Advanced Glass Protection system, which is exceptionally easy to apply, has been found to keep glass in a clean, protected and “like new” condition and appearance for 15 years or longer. 

“Invisible Shield represents a breakthrough in glass and surface coating technology. It chemically seals the pores of glass, porcelain, and ceramics to prevent water, soil, stains and minerals, scratching, etching and other degradation from permanently damaging the surface,” said Howard Ohlhausen, Inventor and Founder of Unelko Corporation.

“It represents the only long-term solution for improved, ‘like new’ appearance and extended life of glass and tile.”

Invisible Shield PRO 15 also increases the scratch resistance of glass by more than 93%, and protects glass against permanent stains, scratches, etching, pitting and other degradation. This eliminates the need for expensive, labor and time-consuming glass restoration. 

In addition, Invisible Shield PRO 15 helps to prevent the need for follow-up cleanings. Residential glass, hotels, and landmark buildings will stay cleaner longer, and in excellent condition and appearance once protected with Invisible Shield. 

Some of the companies and/or types of buildings and glass that have benefited from Unelko’s Invisible Shield Glass Protection include: Marriott, Hyatt, Hilton, Blue Green Vacations, MGM hotels, Major Hospitals, Stadiums, Airports, Autos/Buses, Cruise Lines, Theme parks like Disney and Sea World, Aquariums, the Smithsonian Institute, Louvre Museum, Vanderbilt Home, Solar Farms, Retail Glass Fronts and Buildings including Apple stores and high-rise buildings.

Speaking of high-rise buildings, Anita Vigil, Director of Operations at Skydeck Chicago in Willis Tower in Chicago, noted that the harsh weather conditions, including winds that blow up to 100 miles per hour, can be tough on the Tower’s glass.

“More than average dirt, grime, debris and pollution is thrown at our windows. The Invisible Shield protected glass stays so much cleaner and has saved our team more than 35% in labor savings, requiring much less extensive re-cleaning,” she said.

As Mark Evitt, Managing Director of APQ Australia noted, Unelko’s Invisible Shield glass coatings are “cutting edge.”

“Their products’ protective benefits, repellency, durability, performance, and scratch resistance properties exceed all other coatings, and has helped us earn the trust of some of the most prominent names in the glass industry,” Evitt said.

Peter Justo, Owner of the nationally recognized commercial cleaning company Enviromaster in Princeton, New Jersey, said that the Invisible Shield products are “phenomenal.”

“We use the product somewhere on glass almost every day. In today’s business climate, you need products that help us function efficiently and deliver quality performance to our customers. The Invisible Shield Coating fulfills those needs,” Justo said.

As Lee Sparaco, Glassologist and Owner of Allied Glass in New York City noted, Invisible Shield has been “time tested” on glass and tile, and has exceeded expectations. 

“Invisible Shield has preserved the integrity of many of my glass and tile projects, which are exposed to the harshest conditions and elements for more than two decades,” Sparaco said.

Piotr Plaza, Owner of Krysztal, has tested many types of protective coatings for glass. Invisible Shield PRO 15 Glass Coating has been found to offer the best performance, is the easiest to apply and is the most competitively priced product.

“If you want to be the best, you must work with those who are the best and we believe Unelko is a leader in Advanced Surface Coatings and After Care Products,” Plaza said.
