A Window You Feel Every Day

Clean Modern Design, with Smart European Ventilation

Most windows in the U.S. open in just one way. Slim Aero combines a clean, flat, modern design with the everyday comfort of European Tilt & Turn operation. One handle controls four positions:

Handle up: Tilt mode
The sash tilts in slightly at the top, letting fresh air in while the window stays secure. Rain stays out, sudden drafts are avoided, and there is no fully open sash to worry about when kids or pets are around.

Handle up: Tilt mode
The sash tilts in slightly at the top, letting fresh air in while the window stays secure. Rain stays out, sudden drafts are avoided, and there is no fully open sash to worry about when kids or pets are around.
Handle at 45°: Micro-ventilation
The window looks closed, yet a subtle gap allows a gentle, constant exchange of fresh air, a discreet way to refresh the room without opening it to the outside.
Handle horizontal: Turn mode
The sash swings fully inward for maximum airflow and makes cleaning the outside of the glass easy, even on upper floors.
Handle down: Fully locked
The sash is pulled tightly against the frame and sealed for a quiet, secure, draft-free interior.

Why it stands out:

A modern, architectural window with intelligent European ventilation, security and everyday comfort built in.

Three Designs, Slim Lines and a Robust Sash

Slim Aero keeps the clean, slender look of its slim frame and pairs it with a more substantial sash. The result is a window that still looks lighter and more refined than typical American windows, while the sturdier sash adds rigidity, carries large, heavy glass with ease and gives the window a solid, premium feel every time you open and close it. It comes in three distinct designs:

Cubic
Completely flat surfaces and crisp, clean lines. A pure, minimal look for modern and contemporary architecture.

Completely flat surfaces and crisp, clean lines. A pure, minimal look for modern and contemporary architecture.
Classic (Steel Look)
The refined look of traditional steel windows, with a putty-line glazing profile and a weather bar at the base of the sash. The elegance of steel with the comfort and easy care of modern aluminum.
Ferro
Inspired by early 20th-century industrial windows, with a distinctive projecting bar at the bottom of the sash. It adds depth and character for an authentic industrial-loft feel.
Clean finishing
Whichever design you choose, the hinges are hidden inside the profile and the drainage is concealed, so no plastic caps or visible hardware interrupt the clean lines.

The result:

A clean, architectural window in the style that fits your home, with the strength and solid feel of a robust sash.

Serious Energy Efficiency, Year-Round

A window should let in light, not let your heating and cooling escape. Slim Aero is engineered for real comfort in every season.

Thermally broken frames
Aluminum is strong, but on its own it conducts heat. That's why every Slim Aero frame and sash is built with an advanced thermal break: insulating components separate the inner and outer aluminum, so outdoor heat and cold don't travel through the frame into the room. The frame stays comfortable to the touch, without cold spots or condensation.

The frame stays comfortable to the touch, without cold spots or condensation.
Energy-efficient double or triple glass
Choose double- or triple-pane insulated glass with a Low-E coating and argon gas fill. The Low-E coating lets daylight through while reflecting heat: it keeps warmth inside in winter and blocks the summer sun’s heat from entering the room. Warm-edge spacers keep the edges of the glass free from cold lines and condensation.
One complete system
Together, the insulated frame and high-performance glass work as one system, keeping the room cool in summer, warm in winter and comfortable right up to the glass.

What you get:

Year-round comfort, more stable indoor temperatures and lower heating and cooling bills, in a clean, modern window.

A True Compression Seal: No Drafts, No Noise

Most windows in American homes, like single-hung, double-hung and sliders, seal with brush or sliding weatherstripping. The sash slides past it, small gaps remain, and over time the seal wears down, letting in drafts, dust and noise. Slim Aero closes with a true compression seal instead.

How the compression seal works
When you turn the handle down, multiple locking points around the sash engage and pull it firmly and evenly against the frame. Durable EPDM gaskets are compressed all the way around the perimeter, forming a continuous, practically airtight barrier. Nothing slides against the seal, so it keeps sealing like new for years. The robust sash stays perfectly straight and keeps that pressure even along every edge.

No drafts, no leaks
The compressed gaskets keep out drafts, dust and wind-driven rain, even in stormy weather.
A quieter home
A compression seal combined with insulated glass dramatically reduces traffic, wind and street noise. With acoustic glazing, even a busy street becomes a calm background.
Security
The same locking points that create the seal also hold the sash at multiple points rather than one, and the sturdy sash makes the window even harder to force.

What you feel every day:

No drafts, a noticeably quieter room, and the solid, reassuring close of a true European compression-sealed window.

Designed Around Your Architecture, Down to the Details

Slim Aero lets you shape every visible detail of the window to match your home.

Colors, grids and handles
Choose from the full RAL color range, from matte black and deep anthracite to soft neutrals or bold accent tones, and finish the inside and outside in different colors if you like. Grids can add architectural rhythm to the glass. Slim Aero offers solid, extruded grid bars on both sides of the glass, so they look like true divided lites rather than thin decorative strips. Handles come in a range of styles and finishes, so even the smallest visible detail matches the hardware and design language of the room.

A durable factory finish
The finish is applied and baked on at the factory, so it resists scratches, fading and daily wear and keeps its look for years.

The result:

An aluminum window system you can tailor with precision, from a clean, minimal sheet of glass to a graphic grid pattern.
