Chalco Aluminium Casement Windows: The Ideal Choice for Energy Efficiency and Sustainability

An aluminum casement window is a traditional window type where the window frame is made of aluminum and opens outward or inward with a side hinge design. It is one of the most widely used window types. This design allows the window to open completely, offering excellent ventilation. The high strength and durability of aluminum allow for thinner frames and larger glass areas, providing maximum visibility.

As a leading aluminum processing manufacturer, Chalco can design and produce aluminum casement windows that meet the requirements of standards such as EN 13115, EN 13126, EN ISO 12567, EN 12210, and more. With the full industry chain advantage from raw material sourcing to production and assembly, Chalco offers high production efficiency, fast delivery, and prices 20% lower than other professional door and window companies of the same quality.

Safety features of Chalco aluminum casement windows

1. High-Strength Aluminum Window Frames

Chalco uses high-strength aluminum alloy frames with reinforced designs to provide superior impact resistance. These frames effectively prevent forced entry and vandalism while offering excellent corrosion and weather resistance for long-lasting durability and high security.

2. Safety Glass

Aluminum casement windows are equipped with laminated or tempered safety glass. Even if the glass breaks, the shards stay in place, significantly enhancing shatter resistance and preventing break-ins. This provides extra anti-theft protection.

3. Multi-Point Locking System

Chalco’s aluminum casement windows are equipped with a high-security multi-point locking system, which locks the window at several points. Simply turn the key to lock all points, providing superior resistance to forced entry.

4. Standard Key Locking Handles

To further enhance security, windows come with standard key locking handles, preventing unauthorized opening and tampering, thus improving anti-theft performance.

Energy-saving design of Chalco aluminum casement windows

Low U-value Enhances Insulation

Chalco's aluminum casement windows feature a double-glazed design, achieving a U-value as low as 1.4 W/m²K. A lower U-value means better insulation, effectively reducing heat loss and improving overall energy efficiency.

For higher thermal insulation, triple-glazed versions can achieve a U-value as low as 1.0 W/m²K. In cold regions, such low U-values significantly reduce energy costs and save on heating during long winters.

Efficient Sealing Design

Our casement window frames feature three sealing strips: exterior, interior, and an insulation strip in the middle. This design effectively prevents air leakage and heat dissipation. The combined action of these strips reduces heat transfer through the window frame, enhancing thermal insulation performance.

Polyamide Insulation Materials

The aluminum window frames use polyamide insulation strips, effectively blocking heat transfer and enhancing the thermal performance of the frame, making it comparable to other materials used in energy-efficient windows.

Chalco Aluminum casement windows finishing options

Anodizing

Anodizing is an electrochemical process that forms a hard oxide layer on the surface of aluminum. This layer offers exceptional corrosion resistance and abrasion resistance. Additionally, the oxide layer can be colored as per requirements, with common colors including silver, rose gold, black, white, and bronze.

Application Scenario: Ideal for high-end residential and commercial buildings, especially in outdoor environments, providing long-term durability.

Powder Coating

Powder coating involves evenly spraying powder coating material onto the surface of the aluminum window, followed by high-temperature curing to form a dense, durable coating. This process offers a wide range of color choices, with classic colors such as black, white, and grey, and over 200 other RAL colors to meet different customer needs.

Application Scenario: Widely used in commercial buildings, residential windows, and architectural projects requiring personalized colors.

Wood Grain Transfer Printing

Wood grain transfer printing uses heat transfer technology to imprint wood grain patterns onto the aluminum surface, simulating the appearance of natural wood. This finish combines the aesthetic appeal of wood with the durability and easy maintenance of aluminum.

Application Scenario: Suitable for architectural projects that require the look of wood but want to avoid the maintenance and lifespan issues associated with real wood, such as in villas and luxury residences.

Glass options for Chalco aluminum casement windows

The glass used in aluminum windows is a key component that affects performance, appearance, and safety. Different types of glass not only impact the thermal insulation and soundproofing effects of the window, but also its strength, safety, and visual appeal.

Flat glass

Flat glass is the most common type of glass, with uniform thickness, typically manufactured using the float glass process. It includes various types of glass with different properties and applications, such as clear glass, tempered glass, colored glass, patterned glass, and more. Depending on thermal and acoustic needs, the glass can be configured as double-glazed or triple-glazed.

Single-Glazed Glass

Single-glazed glass loses the most heat and is prone to condensation and dampness.

Double-Glazed Glass

Double-glazed glass reduces heat loss to a quarter of that of single-glazed glass.

Triple-Glazed Glass

Triple-glazed glass reduces heat loss by an additional 35% compared to double-glazed glass, offering superior energy efficiency and economy.

Low-E glass (coated glass)

Low-E glass (also known as low emissivity glass) is coated with a thin layer of metal oxide that effectively reflects heat while allowing visible light to pass through. This type of glass has outstanding thermal insulation and energy-saving properties, increasing the energy efficiency of the window and extending its lifespan. It is ideal for windows requiring high energy efficiency, as well as UV and infrared control, making it especially suitable for modern green buildings.

Insulated glass

Insulated glass consists of two or more panes of glass with a dry gas (such as air or argon) in between. The panes are sealed with adhesive around the edges to enhance thermal insulation and soundproofing. This makes it an ideal choice for improving energy efficiency and comfort in both residential and commercial buildings.

However, compared to ordinary glass, insulated glass is more costly to produce and may require special design considerations in extreme climates to avoid condensation or breakage between the glass panes.
