A Window You Feel Every Day

A Triple Window with Smart European Ventilation on Both Sides

A triple window should give you a wide, open view and easy fresh air. Slim Aero does both. The large fixed center panel works like a picture frame for the view outside, while the two side panels open with European Tilt & Turn operation, so you can ventilate the room from both sides at once and create a natural cross-breeze. Each side panel has one handle with four positions:

Handle up: Tilt mode
The panel 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 panel 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 panel swings fully inward for maximum airflow. It also gives you easy access to clean the outside of the side panels and the fixed center glass, even on upper floors.
Handle down: Fully locked
The panel is pulled tightly against the frame and sealed for a quiet, secure, draft-free interior.

Why it stands out:

A triple tilt and turn window that combines an uninterrupted center view with flexible, secure ventilation on both sides.

An Ultra-Slim Triple Window in Three Designs

The wider the window, the more the frame matters. A typical triple window has heavy frames and wide mullions that break the view into three boxes. Slim Aero needs remarkably little frame: the visible profile starts at just about 1.3 inches, so the three panels read as one wide, light opening with more glass and less frame. The same ultra-slim triple window is available in three designs:

Cubic
Completely flat surfaces and crisp, clean lines. A pure, minimal frame that lets the wide glass take center stage in 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. You get 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
In every design, the hinges are hidden inside the profile and the drainage is concealed, so no plastic caps or visible hardware interrupt the clean lines across the whole width of the window.

The result:

A wide triple window with ultra-slim sightlines, in the style that fits your home, from strictly modern to timeless steel-look and industrial.

Big Glass, Real Energy Efficiency

A triple window brings in a lot of glass, and with the wrong window that means a lot of lost heat. Slim Aero is built so the wide opening stays comfortable all year.

Thermally broken frames
Every frame and sash has 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 slim profiles stay comfortable to the touch, without cold spots or condensation.

Energy-efficient double or triple glass
All three panels can be fitted with double- or triple-pane insulated glass with a Low-E coating and argon gas fill. The coating lets daylight through while reflecting heat, keeping warmth inside in winter and the summer sun's heat outside. Warm-edge spacers keep the edges of the glass free from cold lines and condensation.

What you get:

A bright, wide window that keeps the room cool in summer, warm in winter and comfortable right up to the glass, with lower heating and cooling bills.

A True Compression Seal on Every Opening Panel

Most windows in American homes, like double-hung units and sliders, seal with brush or sliding weatherstripping. The sash slides past it, small gaps remain, and over time the seal wears down. Both operable panels of the Slim Aero triple window close with a true compression seal instead.

How it works
When you turn the handle down, multiple locking points pull the panel firmly and evenly against the frame, compressing durable EPDM gaskets all the way around its perimeter. The result is a continuous, practically airtight barrier. Nothing slides against the seal, so it keeps sealing like new for years. The fixed center panel is sealed permanently into the frame.

No drafts, no noise
Drafts, dust and wind-driven rain stay outside, and traffic and street noise are dramatically reduced, even across a wide opening. With acoustic glazing, a busy street turns into a calm background.
Security
Each opening panel is secured at multiple points rather than one, making the window much harder to force.

What you feel every day:

A quiet, draft-free room and the solid, reassuring close of a true European compression-sealed window.

A Triple Window Designed Around Your Architecture

A triple window is often the centerpiece of a living room, kitchen or bedroom wall. Slim Aero lets you shape every detail of it.

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 rhythm across the wide 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 to match 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 ultra-slim triple window tailored with precision, from one clean, wide sheet of glass to a graphic grid pattern across all three panels.
