European windows,
engineered in Germany.
Built in the USA.
Tilt-and-turn windows and doors on genuine REHAU® ARTEVO™ profiles with RAU-FIPRO® reinforcement — delivering U-values down to 0.14, near-silent rooms, and a 100-year frame guarantee.

Passive House grade
+50% beyond standard
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 0.14 — 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
One window, engineered for everything.
Open it your way.
Locked
All ten locking points engage around the full perimeter — an airtight, secure seal against sound, air and water.

Two ways to bring European performance home.
Global 70™
Steel-reinforced uPVC tilt & turn — the perfect balance for any home.

Global 80™
Premium REHAU ARTEVO™ with RAU-FIPRO® reinforcement — our strongest, most efficient frame.

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.

Engineered to keep intruders out.
A break-in attempt usually starts at a window or door. European tilt-and-turn units answer with locking and reinforcement builder-grade windows don’t have — and can be specified to certified European burglar-resistance standards.
around the sash
Turn the handle once and up to ten hardened cams rotate into steel keepers around the entire perimeter — there is no single weak point to force.
Certified burglar resistance
Configurable to the European EN 1627 RC1–RC3 resistance classes. RC2 — the level police and insurers recommend for homes — resists a burglar working with screwdrivers, pliers and wedges.
Multi-point perimeter locking
Up to 10 steel locking points engage with one turn of the handle — distributing force around the whole sash instead of one weak spot.
Steel-reinforced frames
Galvanized steel reinforcement runs through the profile chambers, so the frame resists the spreading and flexing burglars rely on.
Laminated security glass
Optional P4A laminated panes (EN 356) bond glass to a tough interlayer — they crack but hold together, defeating smash-and-reach entry.
Lockable key handles
Key-operated handles block the most common attack — drilling to turn the handle from outside — and add child-safety on upper floors.
Mushroom-cam & steel keepers
Hardened cams hook behind steel strike plates, so even a crowbar can’t lever the sash free — leaf and frame lock together as one.
Concealed, tamper-proof hinges
Hinges and hardware are hidden inside the closed frame — nothing exposed outside for an intruder to unscrew or attack.
RC ratings, laminated glazing and lockable handles are available configurations — ask your specialist which package fits your home and local code.
