“View dynamic glass reduces overall  
HVAC energy consumption by limiting  
unwanted heat gain in the summer,but  
allowing beneficial passive heat gain in  
winter by using a tiny electrical voltage  
to the electrochromic nano-coatings to  
darken the tint which deflects solar ra-  
diation,” says Klawhun.

dows. In those instances,  
there is another way to receive the desired benefits of dynamic glass.  
According to iGlass Technology Inc. CMO Maxim Khabur, the company’s poly-  
mer film is a cost-effective alternative compared to dynamic glass that can  
be used to retrofit windows.  
It is designed as a retrofit product, [for] upgrading existing windows, not  
replacing them. As a polymer multilayer film, it can be cut and bent to fit any  
window curvature and shape,” says Khabur. “Our Wisp technology uses low  
voltage for operation, which eliminate all electrical works. “There is no wiring  
or cabling involved.”  
According to Khabur, the sandwich film has an electrochromic polymer  
composition between the two transparent flexible electrodes. Wisp isn’t in-  
dium tin oxide-based, meaning it is less fragile and can be installed on the  
glass directly.  
Existing windows can be upgraded from the inside of a building without  
removing the windows. A power and control bar is snapped to the bottom  
of each window, with a solar panel facing outside. It blocks approximately 3  
percent of the window size.  
Privacy Glass, Please  
Healthcare is Innovative Glass Corp.’s  
fastest growing sector. Patient privacy  
laws play a role, but the company’s LC  
Privacy Glass also provides crucial  
health benefits.  
“Our privacy glass assists in infec-  
tion control. Hospitals that use privacy  
glass don’t need to put up curtains  
or blinds, which acquire bacteria,”  
says Anthony Branscum, vice presi-  
dent of architectural sales at Innova-  
tive Glass. “The privacy glass is more  
easily cleaned, which puts patients  
and hospital staff at less risk while  
allowing hospitals to move patients  
faster.”  
Privacy glass also adds an extra ele-  
ment of safety to a building’s interior.  
“All privacy glass is laminated, so  
by the nature of the fact that it is lam-  
inated it does provide some additional  
security and performs as a Category II  
safety glass,”says Pulp Studio CEO Ber-
