Commercial Aluminium Secondary Glazing

Improve both the thermal and acoustic performance of existing windows in commercial buildings

Add extra performance from your existing commercial windows with aluminium secondary glazing

Commercial aluminum secondary glazing is a window enhancement system designed for commercial buildings. It involves adding an additional layer of glass or acrylic panels on the interior side of existing windows or doors, and these panels are framed with aluminum.

Our range of aluminium secondary windows are designed for double-glazing existing primary windows. Easily fitted and operated, the system allows for cleaning and maintaining both the existing primary and applied secondary window. When installed, the system provides all the thermal and acoustic advantages of double-glazing.

Secondary glazing is a fully independent window system installed to the room side of existing windows. The original windows remain in position and in their unaltered form.

Our commercial secondary glazing is available as open-able, removable or fixed units. The open-able panels can be either side hung casements or horizontal or vertical sliding sashes. These allow access to the external window for cleaning and the opening of both the secondary glazing and external windows for ventilation. Fixed forms of secondary glazing are designed to be removed in warmer months when the thermal benefits are not required.

Benefits of Commercial Aluminium Secondary Glazing

The primary purpose of commercial aluminium secondary glazing is to improve various aspects of a building's performance, including thermal efficiency, noise reduction, security, and more. Here are some key features and benefits of commercial aluminum secondary glazing:

  1. Thermal Efficiency:

    • The additional layer of glass creates a thermal barrier, reducing heat transfer between the interior and exterior of the building. This helps improve energy efficiency by minimizing heat loss in cold weather and heat gain in warm weather.
  2. Noise Reduction:

    • Secondary glazing acts as a sound barrier, helping to reduce external noise levels. This is particularly important for commercial buildings located in busy urban areas or near high-traffic zones.
  3. Security Enhancement:

    • The aluminum frames used in secondary glazing provide an additional layer of security, making it more challenging for intruders to break into the building through windows or doors.
  4. Condensation Control:

    • The extra layer of glazing can reduce condensation on windows, which is beneficial for maintaining a comfortable and healthy indoor environment. Condensation can lead to issues such as mold growth and damage to window sills.
  5. UV Protection:

    • The secondary glazing system can offer protection against harmful UV rays. This helps prevent the fading and deterioration of interior furnishings, such as furniture, carpets, and artwork, caused by prolonged exposure to sunlight.
  6. Customization Options:

    • Aluminum frames are versatile and can be customized to fit various window sizes and shapes. Different types of glass or acrylic panels can be chosen based on specific needs, such as safety glass, acoustic glass, or laminated glass.
  7. Compliance with Building Regulations:

    • Installing commercial aluminum secondary glazing can help buildings meet or exceed local building regulations related to energy efficiency, noise control, and security.
  8. Ease of Installation:

    • Compared to replacing entire windows, secondary glazing is often a more cost-effective and less disruptive solution. The installation process is typically quicker and involves less construction work.
