European windows, engineered in Germany. Built in the USA.

The difference is in the engineering.
European windows are built and installed as one airtight, multi-chamber unit — not a pane swapped into an old frame. Here’s how they compare across what matters most.
Sleek & modern
- Clean lines, large uninterrupted glass panels
- Concealed hinges & multi-point locking hardware
- 14+ wood-grain & solid color foil finishes
Traditional look
- Divided lites & decorative grilles
- Visible frames, smaller glass area
- Single-function open mechanism
Built to hold temperature
- Double, triple & quad glazing up to 2"
- Low-E coatings, argon fill, warm-edge spacers
- U-value down to 0.13 — vs 0.37 economy
Generally less efficient
- Typically double glazing only
- Fewer insulating chambers in the frame
- Economy U-values around 0.30–0.37
Sealed as a complete unit
- Whole window replaced for a tighter seal
- Triple compression seals stop air & water
- Installed by trained European-window specialists
Pane-by-pane replacement
- Individual panes swapped into old frames
- Looser seal, more air infiltration over time
- Quicker swap, lower long-term performance
Open it your way.
Locked
All ten locking points engage around the full perimeter — an airtight, secure seal against sound, air and water.

Tilt-&-Slide Patio Doors
For spaces that can’t fit an inswing door. The sash tilts for ventilation or slides parallel to the fixed unit with the touch of a finger — sealed by the same compression technology.
The numbers economy windows can’t touch.
Independently rated against NAFS, ASTM and ENERGY STAR® standards. Lower U-value means better insulation.
