Impact-resistant products

CINTEC America Anchors Down
CINTEC America, based in Glen Burnie, Md., has unveiled its Blast Window Retention Anchor Systems. The product offers a customized solution for each application and masonry substrate to provide high resistance to explosions.

The anchor system consists of a steel bar enclosed in a mesh fabric sleeve. At the jobsite, the system is inserted into the masonry and then connected to the frames. A specially-developed, non-polymer, cementitious grout is then injected into the sleeve under low pressure. The grout fuses with the mesh, expands band shapes itself around the steel to fit the space. 

The company uses dry or low-volume wet diamond drilling techniques to reduce or eliminate water damage associated with conventional concrete wet drilling.

Numerous Blast Window Retention Anchor Systems are available, and each system is designed to meet the conditions under which it must perform, according to the company.

Products Demonstrate Green Test Results

GlassKote USA, located in Bridgeport, Conn., has announced its glass color coatings have test results demonstrating green (environmental) properties. The company says its products do not have any isocyanates, which are often found in color treatments and are proven to cause chronic illness.

“To our knowledge, GlassKote is the only isocyanate-free, two-part glass coating available in North America,” said Warren Belkin, principal of GlassKote USA. “We are committed to bringing safety and security to companies that are involved in the architectural glass industry, homeowners and businesses that live with these materials.”

The company says it has received test data from independent, certified testing labs in which the GlassKote product was tested to have pull-off adhesion strength of more than 2100 pounds per square inch. It has approvals for structural silicone applications as well. 

DL Labs of Brooklyn, N.Y., conducted ASTM testing for GlassKote USA. The following tests were performed: chemical resistance, ASTM D 1308; adhesion, ASTM D 3359; pull off adhesion strength, ASTM D 4541; pencil hardness, ASTM D 3363; humidity resistance ASTM 4585; blistering after humidity test, ASTM D 714; adhesion after humidity test, ASTM D 3359; and MEK solvent rubs ASTM D 4572/D 3732.

The structural sealant/weatherseal testing was done by Dow Corning. 

Unique Fabrication
The new Taffeta line of glass products is the latest from UltraGlas® of Chatsworth, Calif. The company says that Taffeta offers both unique aesthetic qualities and durability.

According to the company, Taffeta field tiles feature a cross-linear structure embossed on the top surface that creates the effect of taffeta fabric. The tiles are lead free and can be ordered in a variety of standard and custom sizes and thicknesses.

A Brilliant Alternative
A number of new OKACOLOR products are available from SCHOTT North America Inc. of Elmsford, N.Y., as alternatives to body tinted or ceramic frit float glass. According to information from SCHOTT, OKACOLOR offers improved color consistency, depth and brilliance compared to similar products. Production is also said to be less time-consuming than that of coated glass or ceramic frit. SCHOTT says the process allows architects freedom to design colorful graphic exteriors while still meeting structural requirements. 

OKACOLOR technology allows for the complete reproduction of black and white and multi-colored images, as well as solid-color coatings, on heat-strengthened and tempered float glass. The OKACOLOR coatings used implement inorganic pigments instead of infusing colors into the glass, according to the company, and the use of digital origination allows for the reproduction of images over the surface of multiple lites of glass. 

Applications of OKACOLOR glass include monolithic single glazing, laminated glazing and insulating glass on annealed float, tempered and cast glass substrates.

Walking on Sunshine
GlassWalk™ from IBP of Fort Worth, Texas, is a structural glass flooring system that utilizes laminated glass lites from the 12 by 12 inches and individual pieces up to 40 by 45 inches. The concept comes from the company’s 6-inch glass paver floor system, which IBP says is a pre-engineered system that increases the visual appeal of the floor and light transmission, while reducing lead times for product fabrication in both residential and commercial applications.

The GlassWalk system can be installed on-site much like the standard IBP Grid Floor System, which utilizes an aluminum grid framework. The laminated glass is available in more than 30 different ceramic frit patterns that ensure a non-slip walking surface that meets the most stringent codes, according to the company. An open weave frit pattern can be applied to the top surface for slip resistance without an obscurity layer below. 

Special order laminated glass can be made with company logos, directional signage or custom patterns screened on the interior glass surface. Custom radius corners, curves or special sizes or shaped laminated glass can be created, as well.
