Aluminium Curtain Wall Systems | Altegra

Curtain Wall Systems

High performance aluminium curtain wall solutions for new and refurbished buildings.

Designed with enhanced thermal and structural performance to meet current building regulations.

Altegra's curtain wall systems have been developed and tested to suit most environments, including low, medium and high rise applications. Commercial and retail applications, transport terminals, health service buildings and educational establishments are just a few of the markets in which Altegra Window & Door Systems has a well earned reputation for service, quality, delivery and technical support.

The systems comprise six suites, with sightlines between 50mm and 52mm* and various mullion and transom depths, including components which can be constructed using stick build and ladder frame methods. The systems are zone drained and pressure equalised, and the SF52 system can also be mullion drained.

As with all Altegra products, our curtain wall systems are manufactured to exacting standards, enabling economy to be combined with strength, achieving many years of aesthetic, low-maintenance performance.

Aluminium curtain walling is a popular building envelope system used in modern architecture. It consists of a lightweight, non-corrosive aluminium frame, which is designed to support glass or other infill panels.

Here are some of the features and benefits of our aluminium curtain walling systems:


  1. Lightweight: Aluminium is a lightweight material, which makes it ideal for use in curtain walling systems. This makes it easier to install and reduces the load on the building's structure.

  2. Durable: Aluminium is a durable material that is resistant to corrosion, rust, and weathering. This makes it ideal for use in buildings that are located in harsh or humid environments.

  3. Versatile: Aluminium curtain walling can be designed in a range of shapes and sizes, and can be customized to meet specific architectural requirements. It can also be finished in a variety of colours and textures.

  4. Energy-efficient: Aluminium curtain walling can be designed to be energy-efficient, with the use of double or triple glazing and thermal breaks to improve insulation and reduce heat loss.


  1. Aesthetics: Aluminium curtain walling provides a sleek, modern look to buildings, and can be used to create dramatic, visually striking facades.

  2. Natural light: Aluminium curtain walling allows natural light to enter the building, which can improve the overall atmosphere and reduce the need for artificial lighting.

  3. Thermal performance: Aluminium curtain walling can improve the thermal performance of a building, reducing energy costs and improving comfort for occupants.

  4. Sound insulation: Aluminium curtain walling can be designed to provide excellent sound insulation, reducing noise pollution from outside the building.

  5. Low maintenance: Aluminium is a low-maintenance material that requires minimal upkeep, making it a cost-effective choice for building owners.
