The FIRST Passive House Certified Aluminum Windows in the United States, now NFRC Certified!
Redefining the aluminum window experience. The A7 Aluminum Window is often the Series of choice for Passive House projects. Triple pane glass in a thermally broken, fully insulated aluminum frame. The A7, Aluminum Windows with triple-pane glass deliver exceptional comfort and quality across an array of styles and sizes.
An all-aluminum frame with continuous insulation provides excellent durability and quality. Our hardware ensures smooth operation and impeccable style. The A7 delivers an exceptional performance with one of the sleekest profiles available.
The newly designed aluminum frames have changed our thoughts about aluminum windows. Historically, the cold aluminum frames created an increased risk of condensation as well as decreased levels of comfort for the occupants. We are pleased those are problems of the past with the Glo Aluminum Windows Series. The larger thermal break, triple glazing, and durable framing of the A7 achieve a greater level of energy performance and aesthetically clean aluminum frames.
Available in fixed windows, tilt and turn windows, french windows, tilt-only windows, inward opening awning windows, and curtain wall windows. Operable window sizes up to 32 s.f. and fixed windows up to 80 s.f.

Nail Flange
The single-track system consists of thermally separated aluminium profiles and can be installed flush in the floor/ceiling area as well as laterally in the reveals. The sliding sash runs on the outside, eliminating the annoying, visible guideway rail on the inside.
Operation
A button with integrated LED in the window frame controls the sliding window operation. Opening and closing is done manually or fully automatically by means of a drive integrated in the profile.
Sizes & Weights
Big is best – and this is also true for air-lux sliding windows. The air seal allows the system to absorb more building tolerances than conventional sealing systems. This in turn allows for sash sizes of up to 8 × 3.1 m (width x height) or 3.1 × 6 m .
Surfaces and materials
Whether a special wood, architectural bronze or stone, we design door panels in every material and surface finish. The core is always our high quality, thermally insulated aluminium profile clad with the required material.
Safety
The highly resistant air-lux basic construction can be upgraded with additional mechanical components and special glass to the tested resistance class RC3. All safety measures remain invisible and change neither the profile nor the face widths.
Instructions
Bullet-resistant glass and alarm glass can also be used up to an element thickness of 60 mm. Electronic components for monitoring the closing position and locking of the sliding windows make it possible to control and monitor the sliding windows through the building management technology.
