What are the key differences between European and American windows?
Functionally, European windows use tilt-and-turn operation - With just one hand, you can tilt the sash inward for secure ventilation or swing it fully open for maximum airflow and easy cleaning. Performance-wise, European windows are made with double or triple paned glass and carry a low U-value, providing superior insulation with galvanized steel hardware built for outstanding durability. 

What is U-factor or U-value?
The U-factor determines the rate of heat transfer, indicating a window's insulation performance, and measured in Btu/h·ft²·°F. A lower U-factor signifies superior thermal insulation. Many European windows exceed Energy Star and Passive House standards,

What is the difference between U-value and R-value in windows?
U-value measures how well a window prevents heat transfer (lower is better) while R-value measures thermal resistance (higher is better). Windows are rated by U-value rather than R-value, since they are designed to minimize heat loss, not just insulate.

How are European windows installed differently?
As opposed to an American window that is fastened using an exterior nail flange, European windows are secured within the wall opening using heavy-duty steel clips and sealing tape. However, we can offer a nail flange for many of our windows should that be the builders preference. 

Can you install screens and blinds on European windows?
We have screen options for both windows and doors that are simple to install and blend seamlessly with the overall look. Pleated blinds are available in multiple colors and fabrics and mount directly onto the glazing bead to cover the glass while keeping the window frame visible and not interfering with the opening. 

Do European windows last longer than American windows?
Thanks to stronger hardware and superior seals, they can last 40+ years with proper maintenance.

What is the lead time to deliver European windows in the U.S.?
Lead time is about 8-10 weeks from confirmed order to site delivery. All units are made-to-order to millimeter precise specifications over 4-5 weeks of production time followed by 4-5 weeks ocean freight and custom clearance.
