Glass and glazing companies have a major presence at the Construct show this year where they’re reaching architects, spec writers and other industry professionals. Pre-fabrication and solutions for retrofit projects were some of the common themes on the show floor. Construct, sponsored by Construction Specifications Institute, is an architecture, engineering and construction (AEC) educational and expo event being held at the Gaylord National Resort & Convention Center in National Harbor, Md.

Many companies offered new products that mimic the appearance or size of historical glazing systems for retrofit applications. Graham Architectural Products showcased its SR6700 Steel Replica Window, which uses aluminum but looks the same as steel with the same sightlines. Graham metro D.C. business development manager Tom Haines said this product is often used in warehouse to condominium conversions in which the customer doesn’t want to pay for more expensive steel windows to replace the older ones, adding that the aluminum window is more thermally efficient.

Graham Architectural Products’ GT6 window system is suitable for many historic renovation projects due to its varying depth options.

Vacuum insulating glass (VIG) is another solution for retrofit applications. Pilkington Spacia is a VIG product that is 6.2 mm thick. Michael Johnson, regional sales and marketing manager for architectural glass in North America, said that not only is the product energy efficient, but it can be used to reglaze existing systems. For newer construction, the product can be combined in hybrid systems to create even more energy efficiency.

“As codes become stricter, we can’t replace every building. We’re going to have to find a solution and we think this is a good solution,” added Jeanette Weisz, marketing communications specialist.

ChildGard security glazing can be used for new construction or for existing buildings such as schools, transaction windows or places of worship.

Consolidated Glass Holdings (CGH) is another company in tune with the retrofit market. ChildGard was on display at the CGH booth, made by Global Security Glazing and Dlubak, CGH companies. The security glazing product has been tested to ASTM standards to prevent entry for up to six minutes and 40 seconds. Vice president of security sales Ben Baum said he has seen an increase in demand growing within school systems, driven by architects, communities and school security groups. The product can be used in new construction and in retrofits. Unfortunately, Baum explained that in retrofit situations many schools turn to films, which are not bullet resistant. Baum said that CGH is working to educate the market about the advantages of security glass over film products.

On the metal side, PPG is seeing a trend toward polysiloxanes in refinishing due to the concern of harmful isocyanate-based finishes, according to engineering sales project manager Bob Herr.

YKK AP America’s new YWW 60 TU is a thermally broken window wall system with a unitized/pre-glazed option.

YKK AP America focused on its new YWW 60 TU, a thermally broken window wall system, which has a unitized/pre-glazed option. Derick Clutchey, general manager for the Northeast region, said that as the labor market continues to shrink there’s been a shift toward quicker installation requiring less labor. This trend is driving much of YKK’s product development, according to Clutchey.

Pre-fabrication is also a driver for Tubelite, which highlighted its four-sided cassette system. The product allows the glass to be glazed in shop within the carrier frame and then installed onsite, preventing glaziers from having to do four-sided structural glazing completely in the field. Product manager Tom Mifflin said the system integrates with all the company’s 400 series curtainwall products. He explained that the labor shortage has created demand for flexible products.

The show runs through Friday, October 11. Stay tuned to for our continuing coverage.
