Get a Grip
By offering enhanced durability and a lighter-weight single aluminum base shoe molding, Wagner’s PanelGrip 2 design can reduce shipping, labor and inventory costs without sacrificing quality, according to the company. The system, which includes a durable locking mechanism, accommodates tempered, laminated glass as required by the 2015 International Building Code.
According to Wagner, PanelGrip 2 doesn’t require fillers or other glass preparation and provides a broad glass grip range. The non-weld installation can be performed on one side of the glass by a single person using a standard Allen wrench.
A full line of fittings and accessories in a range of options allows for customization, and the extruded aluminum shoe qualifies for LEED credits as a green building material.
A Gray Area
Designed to maximize light transmittance and clarity, PPG Industries’ ultra-neutral, warm-light-gray Optigray glass can work with Solarban-coated solar control low-E glasses to enhance solar control performance.
In a standard 1-inch insulating glass unit, Solarban 60 Optigray glass has visible light transmittance (VLT) of 50 percent and a solar heat gain coefficient (SHGC) of 0.30, which yields a light-to-solar-gain (LSG) ratio of 1.67, according to the company.
With Solarban 70XL glass in the same configuration, Optigray glass generates an LSG ratio of 1.99 based on VLT of 47 percent and a SHGC of 0.24.
As part of PPG’s wide range of tinted float glasses, Optigray glass features an appearance that is lighter and more subtle than that of the Solargray and Graylite II glasses.
Visually Attractive Laminated Glass
A number of new developments in laminated glass are now available from Hornos Pujol, based in Barcelona, Spain. These include its Evalam Visual interlayer material as well as the Automatic EVA Plant “Fast Curing” laminating line.
According to the company, the Evalam Visual decorative interlayer offers better transparency values than PVB with 0.38-mm of thickness. In addition, Pujol says the interlayer’s adhesion is three times higher than PVB. It provides 100 percent UV filtering to 380nm wave, as well as acoustic values that are higher than those of standard PVB, according to the company.
In addition, the company offers the Automatic EVA Plant “Fast Curing” laminating line. This consists of an automatic production line and high-speed convection oven to laminate EVA. According to the company, “Fast Curing” was developed to automate the manufacturing of EVA laminated glass, reducing manufacturing cost and increasing quality.
The company explains that the traditional autoclave laminating process requires significant energy expenditures, while this line requires less energy consumption and lower production costs. In addition, the company says the line does not require controlled humidity and climate conditions to store and process PVB, a nipper roll oven, or significant energy investments, among other benefits.
Channeling the Inner Pro
Technical Glass Products’ (TGP) new high-performance channel glass coating, TGP ProColor, doesn’t require tempering and is bonded to the glass with high adhesion strength to resist chipping and fading.
The coating is available in a wide array of opaque and metallic colors. It can be applied to standard and low-iron Pilkington Profilit channel glass options in all available textures. For added protection and opacity, it is also available with an optional flood coating.
Doors that Stack Up
Aluminum bi-fold accordion doors, which can be used in indoor/outdoor living spaces, are available from PRL. The system is thermally broken for increased energy efficiency, and can incorporate different finishes, such as a wood veneer inside and a weather-resistant finish outside.
The doors offer air/water protection with optional hurricane impact performance and sound control ratings when constructed with laminated glass. One advantage of the doors, according to the company, is they can be stacked, creating a completely unobstructed view.
Vetrotech’s New View
Keralite Select from Vetrotech Saint-Gobain is a fire-rated glass technology designed to preserve color viewing while ensuring occupant safety. According to the company, the ceramic glass combines patent-pending surface polishing technology with advanced composition creating a sharp, accurate color-viewing product.
The glass has a color-rendering index of 97.1 (out of 100), the highest R96a value for glass ceramics, and the lowest haze value at 0.5 percent, according to the company. It adds that the surface doesn’t have an “orange peel effect,” compared to similar products and has no cloudy appearance.
According to the company, the glass has a high visible light transmission, which can help contribute toward LEED credits. The glass also has low UV transmission. It is available in thicknesses of 3⁄16- and 5⁄16-inches, and in 20-, 45-, 60-, 90- and 180-minute fire-ratings. It is also available in large sizes and in patterned, opaque and optional colors and tints.
Large, in Charge
Safti-First’s SuperLite III-XL 60-120-minute fire resistive multilaminate is available in butt-glazed assemblies with a maximum single panel size of 6,975 square-inches, giving architects clear views and transparency. The product has the largest fixed-frame glass panel in the industry at 5,978 square inches, according to the company.
Listed and labeled by Underwriters Laboratories, SuperLite III-XL meets ASTM E-119 and ANSI/UL 263 up to two hours with hose stream. It also meets the federal maximum impact safety standard.
The Clean Scene
Ritec International has developed the ClearShield Eco-System, which it says is used for producing its multi-functional, green performance ClearShield Eco-Glass.
According to the company, the Eco-System is applied to any glass--new or old, exterior or interior, in a factory or on-site--resulting in its Eco-Glass, a high-quality glass based on “non-stick,” easy-clean surface protection.
In addition, Ritec says the easy-to-clean surface offers a number of eco-friendly benefits, such as anti-microbial properties, among several others.
In the Balance
The Window Sash Balance Display for customers’ counter areas, from Strybuc Industries, includes an assortment of 31 different series of channel, tube and constant force window balance samples.
When a display is purchased, customers receive a digital flyer to promote the availability of window balances. The display spins 360-degrees and can be a sales tool for identifying balances.
