What are the main differences between European and American windows?
European windows use tilt-and-turn operation, superior insulation, and sleek, modern designs. American windows typically feature double-hung or casement styles, with varying energy performance.

What is a tilt-and-turn window?
Tilt-and-turn windows open in two ways:
  1) Tilt inward for secure, ventilated airflow
  2) Swing fully open (inward) like a door for easy cleaning and maximum fresh air

Are European windows more secure than American ones?
Yes! They have multi-point locking systems that make them far more difficult to break into than standard American windows.

Why are European windows considered more energy-efficient?
The superior insulation of triple-pane glass, airtight seals, and thermally broken frames, dramatically reducing heat loss, making them ideal for energy-conscious homeowners.

Are European windows quieter than American windows?
Yes. Thicker glass, multi-layer seals, and precision engineering provide exceptional soundproofing, perfect for homes in busy or urban areas.

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).

• R-value measures thermal resistance (higher is better).

• Windows are typically rated by U-value rather than R-value, since they are designed to minimize heat loss, not just insulate.

Do European windows have a lower U-value than American windows?
Yes. European windows often have U-values as low as 0.10–0.15 (W/m²K) due to triple glazing, insulated frames, and airtight seals.
American Energy Star-rated windows usually range from 0.20–0.30 (W/m²K), meaning they allow more heat transfer.

Are European windows suitable for extreme climates?
Yes. Their airtight seals and triple glazing make them perfect for cold winters, hot summers, and humid climates.

Can European windows help homes qualify for tax credits or energy efficiency incentives?
Often, yes. Many European windows exceed Energy Star and Passive House standards, making them eligible for federal, state, or utility rebates in the U.S.

How long does it take to get European windows in the U.S.?
Lead times are typically 2.5 to 3 months

Are European windows harder to install?
No, but they do typically install from the inside if you’re not using our nail flange version.

Do tilt-and-turn windows meet fire egress requirements for bedrooms?
Yes, because they open fully like a door, they often exceed egress requirements.

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