Aluminum Windows
Precision-engineered thermally broken aluminum windows for residential and commercial projects — slim sightlines, large glazing capacity, and verified performance.
Overview
Aluminum Windows That Perform as Well as They Look
Aluminum has long been the material of choice for architects and designers seeking maximum glazed area with the narrowest possible frame. When combined with a proper thermal break, aluminum delivers the structural rigidity and sightline slimness that modern architecture demands — without the thermal bridging of older unbroken profiles.
Our aluminum windows are based on the SMARTIA S67 system from Alumil — a 67mm thermally broken aluminum profile designed for demanding residential and commercial applications. The S67 accommodates glazing up to 58mm thick, making it compatible with high-performance triple-glazed units as well as a wide range of specialty glass types.
Polyamide thermal break inserts within the S67 profile separate the interior and exterior aluminum faces, reducing conductive heat transfer and lowering the risk of interior surface condensation. Actual condensation performance depends on indoor humidity, exterior temperature, glazing selection, framing, and installation conditions. Three-level EPDM gasket sealing provides reliable weatherproofing, with the system achieving Class 4 air permeability and watertightness classifications of E900 and E1200 under EN testing standards.
For projects with security requirements, the S67 supports RC2 burglary resistance classification (EN 1627) in appropriate hardware and glazing configurations — a meaningful specification point for ground-floor and accessible windows in residential and commercial buildings.

What Makes the Difference
Features of Our Aluminum Windows
Slim Sightlines
The 67mm frame depth and structural efficiency of aluminum deliver slender sight lines that maximize your glazed area and allow more natural light into the space.
Large Glazing Capacity
Up to 58mm glazing accommodation supports double and triple insulated glazing units with Low-E coatings, acoustic interlayers, or solar-control treatments.
Thermal Break Technology
Polyamide thermal break inserts within the aluminum profile reduce thermal bridging, improving thermal performance and reducing the risk of frame condensation.
3-Level Sealing System
Three levels of EPDM gasket sealing — at the frame, sash, and glass rebate — work together to resist air infiltration and water penetration across a range of weather conditions.
Security Options
RC2 burglary resistance (EN 1627) is achievable in appropriate S67 hardware and glazing configurations — suitable for ground-floor and accessible window positions.
Finish Options
RAL powder coat in virtually any color, anodized aluminum for a refined metallic surface, and wood-effect laminate foils for warmth without timber maintenance.
Available Types
Configuration Options
The S67 system covers the full range of casement and fixed window types within a single profile family, enabling consistent aesthetics across mixed-configuration projects.
Fixed Glazing
Non-opening fixed panels for maximum unobstructed glazed area within the same profile family as opening windows.
Single Casement
Side-hung single sash, inward or outward opening, for reliable ventilation in standard-sized openings.
Double Casement
Two-sash configuration for wider openings, typically meeting at a central mullion or with a removable option.
Tilt-and-Turn
Inward-opening dual-function sash: tilt for restricted ventilation and easy interior cleaning, turn for full casement opening.
Concealed Sash
Hidden-frame sash profile presenting a clean, nearly frameless appearance when the window is closed.
Combination Assemblies
Fixed and opening sashes combined into multi-unit assemblies for large-format window walls and façade applications.
Where They Excel
Best Applications
Modern Residences
Slim-framed aluminum windows are the defining feature of contemporary residential architecture — providing clean lines, large glazed surfaces, and a connection to the landscape.
Commercial Façades
From office buildings to hospitality projects, aluminum windows offer the durability, finish quality, and dimensional stability that commercial specifications require.
High-Performance Buildings
Projects targeting specific air, water, wind, and security classifications benefit from the S67's verified EN performance data and the ability to match glazing selection to project objectives.
