Windows

Types of energy efficient windows

Energy efficient windows are key to making your house more comfortable and reducing your energy bill. These types of windows use new glazing and framing materials. While double glazing is the most common type of energy efficient window, other types can cater to different needs, architectural styles, and budgets:

  • Double glazed windows: The most common, these use two layers of glass separated by a sealed air or gas-filled space. The insulating layer reduces heat transfer, improving energy efficiency.
  • Triple glazed windows: Similar to double glazed windows, they include an extra layer of glass, providing even greater insulation and energy efficiency.
  • Low-E coating: Low-emissivity (Low-E) coatings are thin, transparent layers applied to window glass. They reflect infrared light while allowing visible light to pass through, helping control heat transfer.
  • Secondary glazing: Where it doesn’t make sense to replace existing windows with one of the above options, secondary glazing involves an extra pane of glass or clear acrylic being retrofitted to existing single-glazed windows. This is often a cheaper alternative.

Significant benefits can be obtained by installing energy efficient windows

  • More comfort: Energy efficient windows reduce draughts, cold spots, and heat radiation, creating a more comfortable indoor environment.
  • Save on bills: By minimising heat transfer, energy efficient windows reduce the need for heating and cooling, leading to lower energy bills.
  • UV protection: Some energy efficient windows have UV-blocking properties that protect your furnishings and interior from fading due to sun exposure.
  • Quieter: The insulation provided by energy efficient windows helps reduce external noise, creating a quieter indoor space – great if you have noisy neighbours or traffic noise.
  • Environmental impact: Using less energy to heat and cool your home contributes to lower carbon emissions and a reduced environmental footprint.
  • Home aesthetics: Energy efficient windows are available in various styles, allowing you to maintain or enhance your home's visual appeal.

How to choose and install the right windows

Transitioning to efficient windows involves several steps:

  • Assess: First, consider your climate, orientation, budget, and aesthetics. Evaluate your existing windows to determine the areas that require upgrading.
  • Window selection: Choose the appropriate type of energy efficient windows for different areas of your home. Consider factors like insulation value (R-value), how well the window insulates (U-factor) and the amount of heat from direct sunlight that passes through the window (solar heat gain coefficient). A chat with window professionals can help you make informed decisions.
  • Installation: Proper installation is crucial for optimal performance. Skilled professionals ensure a seamless installation that maximises energy efficiency.
  • Maintenance: Regular cleaning and maintenance of your energy efficient windows ensure their longevity and continued performance.
