Aluminum Windows

More Light.
More Architecture.

Aluminum supports large glass areas with slim profiles. When properly designed, it becomes a durable window system that balances thermal performance, daylight, comfort, and security.

Simply Explained
01 Thermally Broken 02 Made to Measure 03 For Large Glass Areas
How Aluminum Windows Work

More Than a Frame.
One Coordinated System.

Aluminum is lightweight, strong, and corrosion resistant. Because metal conducts heat well, a morn high-performance window depends on a thermally broken frame and the precise interaction of glazing, edge spacers, seals, and installation.

01

Strength Creates Better Views

Its high strength supports larger sizes and slimmer sightlines, leaving more area for daylight and views.

02

The Thermal Break Slows Heat Flow

Insulating struts separate the interior and exterior aluminum shells. Additional insulation zones improve frame performance.

03

Glazing Is Selected for the Site

Thermal performance, solar control, sound reduction, and security can be combined. Climate, orientation, and use determine the glazing configuration.

04

Airtightness Comes from the Details

Multiplicityple seal levels, suitable hardware, and a properly executed wall connection protect against drafts, wind-driven rain, and moisture.

Opening Types

Which opening suits you?

Select an opening type. In the turn-tilt window, you can switch between "Open completely" and "tilt position".

Rotary sashes

Opening laterally in the room - comfortable to clean.

Tilting blades

Topped — safe fission ventilation in rain.

Handle below · closed
Rotary tip

Handle on the right: fully open. Handle above: comfortable tipping.

Window opening to the outside

The sash opens to the outside — the interior remains completely free.

Sculp windows

Two sashes without a fixed bridge — after opening, the center remains free.

2 Floor window with center post

Both sashes can be opened; the fixed central post remains.

Further variants: fixed glazing · swing vans · vertical sliding window.

How It Works

Five Layers.
One Combined Performance.

One strong rating alone does not make a good window. Lasting comfort comes from matching the frame, glazing, seals, hardware, and installation.

01

Frame & Structural Design

The aluminum frame carries the glazing weight and wind loads. System depth, chambers, and reinforcements are selected for the unit size and installation conditions.

02

Thermal Break

Insulating struts interrupt the direct path of heat between outdoors and indoors. Insulation inserts further improve critical areas.

03

Insulated Glass & Edge Spacer

Double or triple glazing, low-e coatings, gas fills, and warm-edge spacers determine thermal performance, solar heat gain, and daylight.

04

Seals & Drainage

Continuous seal levels manage water and limit unwanted air leakage.

05

Hardware & Wall Connection

Hardware transfers loads and locks the sash. The wall connection should be airtight on the interior, insulated through the center, and weather protected on the exterior.

Understanding Performance

Numbers That Actually
Explain Something.

Always compare the complete tested window in the planned size and glazing configuration. Glass-only or frame-only values do not describe total product performance.

Uw

Overall Thermal Transmittance

Uw rates the complete window, including frame, glazing, and edge spacer. In the European system, a lower value means better insulation.

Do not confuse it with Ug or Uf.
U

U-Factor in the U.S.

The NFRC U-Factor also describes heat flow through the entire product, but in U.S. units. A lower value is better here as well.

Compare only ratings based on the same standard and units.
SHGC

Solar Heat Gain

SHGC indicates how much solar heat enters through the window. A lower value reduces summer heat gain; a higher value can take advantage of winter sun in cold climates.

Climate, orientation, and shading determine the right value.
VT

Visible Daylight

Visible Transmittance describes the amount of visible light. Higher values provide more daylight but should be balanced with glare and solar control.

More glass does not automatically mean more comfort.
AL

Air Leakage

A lower air-leakage rating indicates a tighter unit. Opening type, seals, hardware adjustment, and installation all affect the result.

Check the tested size and configuration.
CR

Condensation Resistance

The NFRC Condensation Resistance Index indicates resistance to condensation. A higher rating is better.

Indoor humidity and outdoor temperature still matter.
Key Takeaway

The right window is not a checklist of maximum ratings. It is the right balance of thermal performance, solar gain, daylight, ventilation, acoustics, and budget for the specific site.

Built for Everyday Life

Strong by Nature.
Effortless in Use.

Aluminum is dimensionally stable, corrosion resistant, and easy to maintain. A suitable finish, regular cleaning, and maintenance of seals and hardware are also essential for a long service life.

Slim, Large-Scale Designs

High load capacity supports panoramic units, heavy glazing, and clean architectural sightlines.

Weather-Resistant Finishes

Powder coating or anodizing protects and defines the frame. Exposure, color, and location determine the right specification.

A Circular Material

Aluminum can be recycled repeatedly. Design for disassembly, clean material separation, and recycled content improve its environmental profile.

Plan Comfort from the Home

Accessible operation, concealed hardware, opening restrictors, sensors, and forced-entry resistance can be combined for the intended use.

Finishes

Color Shapes the Design.
Pretreatment Provides Protection.

RAL powder coatings offer a wide range of colors and textures, while anodizing emphasizes the metallic character. Coastal and industrial environments call for enhanced pretreatment matched to the corrosion exposure.

Four Steps to the Right System

Home with the Requirements.
Then Choose the Window.

Good planning does not start with a frame series. It starts with the site, architecture, and use — which determine the system, glazing, opening type, and installation details.

  1. 01

    Understand the Site

    Document climate, wind, building height, coastal exposure, orientation, and shading.

  2. 02

    Define How It Will Be Used

    Clarify views, ventilation, operating height, accessibility, cleaning, and security.

  3. 03

    Set Performance Targets

    Define whole-window U-value, SHGC/g-value, daylight, acoustics, air leakage, and water resistance for the project.

  4. 04

    Coordinate the Details

    Coordinate unit sizes, glazing weights, anchoring, sealing, drainage, and maintenance access.
