Double-hung window from the Stilo 50 series in bronze-anodized finish
10 July, 2026
When we think about replacing the windows in our home, we tend to focus only on aesthetics. However, windows are the main point where energy escapes from our home. Choosing high-quality aluminum window frames isn’t an expense—it’s an investment that you’ll see reflected in your electricity and gas bills.
What should you keep in mind when choosing your windows?
- Thermal Break (TB): Aluminum is a conductive metal, so high-quality modern windows incorporate an insulating material (usually polyamide) between the inner and outer surfaces of the profile. This prevents outside cold or heat from being transferred indoors.
- The type of glazing: A good aluminum profile should be paired with double- or triple-pane glass containing an air space or argon gas.
- The type of opening: Casement or tilt-and-turn windows generally provide a tighter seal than traditional sliding windows.
Key Benefit: Replacing your old windows with aluminum windows featuring RPT can reduce energy consumption for heating and cooling by up to 30%.
