Power*e Glass Specifications

Standard Power*e™ double paned insulated sealed window manufactured by Radiant

Glass Industries LLC incorporating Pilkington Tek-15 tempered low-e safety glass

(inside glass pane) and any tempered glass (outside glass pane). Typical maximum

glass size is 35 ft2. Overall unit thickness can be specified from ⅝ inches (15.875 mm)

to 11/16 inches (26.9875 mm). The Power*e™ Glass unit uses an Edgetech™ True warm

edge super spacer technology and is sealed using D-2000 reactive hot melt butyl

sealant. All electrical heating components are sealed within the unit except for

electric and control wires that extend from one corner of each sealed unit.

The maximum glass surface temperature is 115ºF. The typical warm-up to sensible

emittance time is 8 to 10 minutes. Power*e™ Glass windows are extremely efficient:

• combining radiant heat and building heat loss stoppage through the glass

• pulsing the electric current to maintain the preset surface glass temperature

• enabling lower ambient air temperatures without comfort loss.

Actual power output and consumption varies with variables such as glass surface

temperature, inside and outside temperature differences, room configuration and

other heating sources.

Power*e™ Glass units can be used as windows, glass walls and panels, and glass

divider walls for cubicle conditioning in the core of the building. Power*e™ Glass

units can be adjusted to any target temperature up to 115ºF and can be installed in

parallel or series for on-demand zoned heating. Exterior Power*e™ Glass windows

stop 100% of other building heat loss through the heated glass.

Power*e™ Glass windows incorporate a number of safety features including tempered

glass, automatic glass temperature monitoring and automatic power cutoff for

excessive operating temperatures or glass breakage. The Power*e™ Glass unit is

certified by Intertek ETL - SEMKO Testing Services to Safety Standard for Sheathed

Heating Elements, UL 1030 7th Edition.

Frames for Power*e™ Glass units are required (supplied by installer) and may be any

metal, wood, vinyl or other industry standard framing. Typical frames will cover or

hide all internal electrical heating components.

Power*e™ Glass windows are designed to be controlled by industry standard climate

controls. 120 volt AC to 50 volt DC power supplies or inverters sized to the Power*e™

Glass windows are required. The maximum voltage input is 50 volts DC, and the

maximum current input is 15 amps. Typically a Power*e™ Glass window operates at

50 volts, 4 amps, 200 watts and 40% duty cycle. Power*e™ Glass windows are designed

to use Class 2 wiring (AWG).

Power*e™ Glass windows shall be installed by qualified glazing contractors and

electricians according to all applicable codes.
