Low E Options
Triple Glazed System (1 3/8” Overall)
Consists of three panes of glass and two 1/2” sealed air spaces. While it uses the same sealing and glazing materials and techniques as in Double Glazed System, the addition of one extra pane of glass and 1/2” air space dramatically improves the performance of your windows by reducing heat loss, conserving energy and increasing noise resistance.
SOLAR GAIN LOW E GLASS
The best glass for most applications in a northern climate. It has a very high retention rate of the heat in your home in winter and prevents heat gain in summer. Since as much as 95% of your energy expense for heating and cooling combined goes for heating, this glass is more cost effective than other glass without a high SHGC.
SOLAR SHIELD LOW E GLASS
Is chosen for uses where cooling costs outweigh heating costs in your energy usage, or where summer discomfort from heat build-up should be an important concern. This is the best glass for most applications in a southern climate. It has a very high reflection rate of the radiant outside heat to prevent heat gain in summer and in winter it still retains radiant heat once you turn on your furnace!
Argon Gas filled units reduce your window’s conduction and convention of heat. Argon works well with Low E glass to maximize your new window’s energy efficiency and performance.
Krypton Gas filling works where Argon can’t! It is ideal for smaller air spaces created in triple glazing and can be combined with Argon in intermediate size spaces.
Foam-Insulating Windows Close the Gap on Energy Costs
Best of all, Foam-insulating windows provide an additional benefit to the already impressive advantages of warm edge and gas filling upgrades. The frame makes up about 15% of a window. Foam can provide up to a 10% reduction in heat loss through the window frame.
