Triple-Glazed Windows
Triple-glazed windows are becoming increasingly popular due to their significant performance and energy-saving improvements. Our Energy Star-certified triple-glazed windows have an additional third pane included for insulation, compared to double-glazed windows with two panes and additional space between each section of glass.
This third window pane helps keep heat from escaping and reduces condensation. These windows can improve energy ratings by as much as 20 to 30% when comparing SHGC or U-value factors.
Low-Emissivity (Low-E) Glass from Germany
In this day and age, energy efficiency is on everyone’s mind. It’s no longer just about the environment — it’s about keeping energy bills low and ensuring homes and buildings boast greater thermal efficiency. Dalmen Windows are on the leading edge of this initiative, and our products are proudly using Saint-Gobain’s SGG Planitherm® LUX Glass glazing.
Produced in Germany, these new Low-E coated glasses are dedicated to triple-glazed units for better comfort, no matter the window size. Planitherm® LUX offers exceptional thermal insulation while maximizing passive solar gains:
Thermal Insulation: Ug = 0.7 W/m²K | Solar Gain: g = 62%
