A Window You Feel Every Day
Everyday Comfort, Handled More Intelligently
Fresh air should feel easy, controlled, and fully in tune with how you live. Alu Energy aluminum windows offer four functional handle positions instead of the usual open-or-closed limitation, giving you a more refined way to ventilate, secure, and enjoy your space every day.
Handle up: Tilt mode
Air flows in gently from the top while the window remains secure. It helps reduce the chance of rain entering, avoids the exposure of a fully open sash, and protects the window from sudden drafts.
Handle at 45°: Micro-ventilation
The window appears closed, yet a subtle opening allows light airflow into the room. A discreet way to refresh the home without opening it to the outside.
Handle horizontal: Turn mode
The sash opens inward for full ventilation, easy cleaning, and comfortable everyday use.
Handle down: Fully locked
The sash seals tightly against the frame for a quieter, more protected, and more comfortable interior.
Why it stands out:
This is more than ventilation — it is intelligent daily comfort built directly into the Alu Energy window system.

Architectural Aluminum, Engineered for Serious Thermal Comfort
Alu Energy is designed for homeowners and architects who want the strength and clean architectural presence of aluminum without giving up real thermal comfort. The result is a window system that helps keep interiors warmer in winter, cooler in summer, and more consistently comfortable all year long.
Advanced thermal break with two insulating components
The frame is built with an advanced thermal break system featuring two insulating components, including a two-component central seal. This significantly reduces thermal bridging and elevates comfort far beyond what many people expect from aluminum.
EPS thermal insulation inserts in the outer frame
The outer frame is enhanced with EPS thermal insulation inserts, further reducing heat transfer and helping create a more stable indoor environment close to the glass.
Low-E insulated glass with argon fill
Available with energy-efficient double- or triple-pane insulated glass units made with Low-E glass and argon gas fill, helping reduce heat transfer, improve thermal efficiency, and support a more consistent indoor climate.
What you get:
The presence and durability of aluminum, paired with the kind of year-round thermal comfort expected from a premium modern window system.
A Tighter Seal, a More Solid Close, and Greater Peace of Mind
A premium window should do more than close — it should feel reassuring every time it does. Alu Energy aluminum windows are engineered to seal more tightly than many standard systems, creating a noticeably quieter, calmer, and more secure interior.
Advanced perimeter sealing with multi-point locking
When the handle is turned into the locked position, multiple locking points engage around the sash and draw it evenly toward the frame across the full perimeter. That even compression helps create a tighter all-around seal.
Reduced drafts, softer outside noise, and a more solid feel
The compression reduces drafts, softens outside noise, and gives the window a distinctly more solid, premium feel in daily use — a noticeable difference from standard systems.
Stronger multi-point security barrier
Because the sash is secured at multiple points rather than just one, it is more resistant to being forced away from the frame. Combined with tempered or otherwise specified safety glazing, it helps create a stronger and more confidence-inspiring barrier for the home.
What you feel every day:
A quieter room, a tighter close, and more confidence each time the window is locked.
Designed Around Your Architecture, Down to the Details
A premium window should not only perform beautifully — it should feel fully resolved within the architecture of the home. Alu Energy offers broad design customization, allowing you to shape the overall look with the same level of intention as the rest of the project.
Full RAL color range and woodgrain finishes
Choose from the full RAL color range, as well as woodgrain finishes for a warmer, more natural expression.
Grids with dual inside/outside color options
Grids are available in a range of styles and patterns, with the option to specify different colors for the interior and exterior sides — adding architectural character while preserving design consistency.
Modern handles in any RAL color
Modern handle designs are available in any RAL color, allowing even the smallest visible details to align with the design language of the space.
Concealed hinges for a cleaner, more minimal look
For a cleaner and more architectural appearance, concealed hinges are available to reduce visible hardware and support a more minimal presentation.
The result:
An Alu Energy window system you can tailor with precision — from expressive architectural detailing to a cleaner, more minimal look.
