Aluminium spacer bar

Introduction to Aluminium Spacer Bars

Aluminium spacer bars are integral components in the fabrication of insulated glass units, commonly found in modern window and door systems. These bars are designed to separate two panes of glass, creating a space that is filled with air or inert gas to enhance thermal efficiency. The role of aluminium spacer bars is crucial in maintaining the integrity and performance of double-glazed units.

Types and Applications

The versatility of aluminium spacer bars is reflected in their various types, including standard, bendable, and warm-edge spacers. Each type serves a specific function, from providing structural support to improving the thermal performance of the glazing unit. These spacers are not only used in residential and commercial windows but also in specialty applications such as refrigeration, automotive, and aerospace industries where insulation is paramount.

Features and Materials

Aluminium spacer bars are characterized by their durability and conductive properties. Made predominantly from aluminum alloys, such as the 6000 and 7000 series, these spacers are treated with surface finishes like polishing or mill finishing to enhance their resistance to environmental factors. The material's innate strength allows for operations like cutting, decoiling, and punching, facilitating customization for specific glazing requirements.

Advantages of Aluminium Spacer Bars

The use of aluminium spacer bars for double glazing is associated with several advantages. Their lightweight nature contributes to ease of handling and installation, while their strength ensures longevity and resistance to deformation. Aluminium's excellent thermal properties aid in reducing heat transfer, thus contributing to the energy efficiency of the insulated glass units.

Selection Considerations

When selecting aluminum spacer bars, considerations such as compatibility with the glass type, the desired thermal performance, and the specific application are essential. The choice between extruded or cold-drawn bars will also impact the overall functionality of the spacer, with each manufacturing process offering distinct benefits in terms of precision and strength.

Environmental Impact and Sustainability

Sustainability is a growing concern in construction materials, and aluminium spacer bars contribute positively in this regard. Aluminium is a recyclable material, and its use in spacer bars ensures that the components can be repurposed at the end of their life cycle, reducing the environmental footprint of the insulated glass units they support.
