The AW113 series is one of ALPES’ flagship tilt and turn windows, combining the convenience of inward tilting for gentle ventilation with full side-hung opening for easy cleaning and emergency escape. Yet a window is only as good as the glass it carries. Glazing covers the vast majority of the window’s visible surface, and it determines most of the thermal, acoustic, and safety performance you actually feel in a building. In this guide, we walk through every glass option available for the AW113 series so you can specify the right configuration for your project with confidence.
Before looking at specific options, it helps to understand what glass actually does in a window system. The right glazing does four jobs at once:
Because the AW113 series is built around a thermally broken aluminum frame, pairing it with the right glass lets you unlock the full potential of the system rather than leaving performance on the table.
Single tempered glass is the most economical starting point. The glass is heat-treated so that when it breaks, it crumbles into small, blunt granules rather than sharp shards, which makes it far safer than ordinary annealed glass. It is a practical choice for interior partitions, mild climates, or projects where budget is the primary concern. Common thicknesses range from 5mm to 8mm.
Insulated glass, also called an insulating glass unit (IGU), pairs two panes of glass separated by a spacer and a sealed air or gas cavity. This trapped layer of air dramatically slows heat transfer compared with a single pane. Typical configurations such as 5+12A+5mm or 6+16A+6mm are the standard for modern residential and commercial projects, and they noticeably improve both thermal comfort and condensation resistance. For the AW113 series, the deep glazing pocket of the frame comfortably accommodates these thicker units while keeping the slim sightline you expect from a premium window.
Laminated glass bonds two layers of glass together with a tough PVB interlayer. If the glass is struck, the fragments stay glued to the interlayer instead of flying, which makes it an excellent choice for high-rise buildings, homes with children, and locations exposed to strong wind-borne debris. The interlayer also absorbs sound, so laminated glass delivers noticeably better acoustic performance than standard float glass of the same thickness. Common configurations include 5+0.38PVB+5mm or 6+0.76PVB+6mm.
For the highest level of thermal and acoustic performance, triple glazing adds a third pane and a second sealed cavity, typically configured as 5+9A+5mm+9A+5mm. Triple-glazed units are the go-to choice for passive-house projects and cold climates, where every fraction of a U-value counts. Combined with the AW113 series’ thermally broken frame, triple glazing lets you reach very low heat-loss levels while keeping the interior surface warm and free of drafts.
Low-emissivity (Low-E) glass carries an ultra-thin metallic coating that reflects heat while letting visible light pass through. In summer it reflects outdoor heat away, and in winter it traps indoor warmth, which can cut heating and cooling costs significantly. Low-E coatings are typically combined with an insulated unit and an inert gas fill such as argon to maximize performance. For sunny regions, Low-E glass is one of the smartest upgrades you can make to an AW113 window.
Beyond performance, glass also shapes the look and feel of a space. Tinted glass reduces glare and solar heat gain while adding a subtle color to the facade, and frosted or patterned glass provides privacy for bathrooms and street-facing rooms without sacrificing natural light. ALPES offers a range of tint and style options, and custom glass types are available on request, so the AW113 series can be tailored to match any architectural vision.
There is no single “best” glass — the right choice depends on where the project is located and what you need the window to do:
Whatever glass you choose, the AW113 series is engineered to get the most out of it. The frame is extruded from 6060-T66 aluminum with profile thicknesses from 1.8mm to 2.5mm, meeting and exceeding new national standards. PA66GF25 thermal break strips and a multi-chamber design keep the frame itself from becoming a thermal bridge, while a dual-matrix eight-layer sealing system locks out wind, rain, and noise. The hardware is supplied by trusted German and European brands including ROTO, Winkhaus, CMECH, and Wehag, with 360° locking point distribution for full-perimeter security. Every unit is tested for corrosion resistance and structural strength, so the window performs as well in year ten as it does on day one.
ALPES is a professional tilt and turn window manufacturer based in Foshan, Guangdong, China, with a 100,000 m² production base and two manufacturing centers. Because we produce in-house, we can customize everything — glass configuration, frame color, hardware, and dimensions — and offer competitive direct-from-factory pricing without compromising on quality. Our aluminium tilt and turn windows have been installed in luxury residential and commercial projects across the Middle East, Australia, and beyond.
