This material creates a barrier that minimizes the flow of heat and cold through the profile, leading to improved energy efficiency.

Thermally broken frames also mitigate condensation issues on the interior surfaces of the frames, which can damage the structure and cause mould growth if left unchecked. By reducing condensation, these frames also help maintain a healthy indoor environment.

Insulated Panels

Another way to improve the thermal performance of aluminium profiles is by incorporating insulated panels. These panels consist of a layer of insulation material, such as foam or mineral wool, sandwiched between two layers of aluminium. When used in the construction of doors or window frames, insulated panels can significantly enhance a building’s energy efficiency.

Insulated panels can be customized in terms of thickness, insulation type, and the aluminium gauge, providing varied degrees of insulation, weight, and cost according to a project’s requirements. Insulated panels not only provide thermal insulation but also offer acoustic insulation and increased structural strength.

Optimal Weatherstripping

To further improve the thermal performance of aluminium profiles, properly sealing gaps and areas where air infiltration can occur is essential. This is achieved through the use of weatherstripping materials, such as gaskets, seals, and brushes, which are installed around the perimeter of doors or windows.

By creating an air-tight seal, weatherstripping prevents drafts, reduces heat loss, and ensures the optimal performance of insulation materials. Carefully selected weatherstripping materials can significantly impact and enhance the thermal performance of aluminium profiles in doors and windows.

Glazing Options for Energy Efficiency

Glazing plays a critical role in a building’s energy efficiency, and selecting the appropriate glazing material can have significant performance benefits. Various glazing options can enhance energy efficiency, including:

Low-emissivity (Low-E) glass features a thin, transparent coating that minimizes the amount of infrared and ultraviolet light entering the building while allowing visible light to pass through. This coating helps reduce heat transfer through the glass, leading to better insulation and reduced energy consumption for heating or cooling. Additionally, Low-E glass can help protect the interior from fading due to harmful UV rays.

Double or Triple Glazing

Double or triple glazing involves using two or three panes of glass separated by gas-filled spaces, which provide improved insulation compared to single-pane glazing. This increased insulation reduces heat transfer, lessens noise pollution, and increases security. Triple-glazed windows offer even greater insulation and durability, although they are more expensive and may not be necessary in all climates.

Gas Filling

In double or triple-glazed windows, the space between the glass panes is filled with an inert gas, such as argon or krypton. These gases have low thermal conductivity, meaning they reduce heat transfer better than traditional air-filled spaces, thus improving insulation properties.

Tinted or Reflective Coatings

Tinted or reflective coatings can be applied to glazing materials to control solar heat gain and reduce glare without blocking significant amounts of natural light. Tinted coatings absorb solar energy, which then reduces the transmitted light and heat, while reflective coatings reflect solar energy away from the window. Both methods can help increase energy efficiency and enhance occupant comfort.
