    Thermally Efficient Windows Guide:

     

    Here’s an overview of thermally efficient windows, covering styles, costs, colours, and materials:

    Window Styles

    The most energy efficient window styles include:

    • Fixed windows: These non-opening windows provide the tightest seal and are generally the most energy efficient option.
    • Casement windows: These side-hinged windows that open outward create a tight seal when closed.
    • Tilt and turn windows: Similar to casement windows, these provide good energy efficiency with a tight seal.

    Sliding windows and sash windows tend to be less energy efficient due to their moving parts, though modern versions have improved significantly.

    Materials

    The most common energy efficient window frame materials are:

    • uPVC: Offers excellent insulation, is low maintenance, and tends to be more affordable.
    • Aluminium: Provides good insulation when designed with thermal breaks, is durable, and requires little maintenance.
    • Fibreglass: Very stable with superior thermal performance, fibreglass frames can be filled with insulation.
    • Wood: Naturally insulating but requires more maintenance unless clad with aluminium or vinyl.
    • Composite: Made from wood products and polymers, these offer good insulation and moisture resistance.

    Glazing Technology

    Energy efficient windows utilise several glazing technologies:

    • Double or triple glazing: Multiple panes of glass with gas-filled spaces between for better insulation.
    • Low-E glass: Special coatings that reflect heat back into the home while allowing light to pass through.
    • Argon or krypton gas fills: These inert gases between panes further reduce heat transfer.
    • Warm edge spacers: Used to separate glass panes, these reduce heat conduction compared to traditional aluminium spacers.

    Colours and Finishes

    Energy efficient windows are available in a wide range of colours and finishes:

    • uPVC windows typically come in white, but can also be found in woodgrain effects and various colours.
    • Aluminium windows offer a broader range of colour options through powder coating.
    • Wood frames can be painted or stained in virtually any colour.
    • Fibreglass and composite frames can mimic the look of wood or be painted in various colours.

    Costs

    Energy efficient windows generally cost more upfront but can lead to significant energy savings:

    • Double glazed windows with energy efficient features typically cost 10-15% more than standard windows.
    • Triple glazed windows are more expensive than double glazed, but offer superior insulation.
    • Costs vary widely based on frame material, size, and specific energy efficient features.
    • While more expensive initially, energy efficient windows can reduce heating and cooling costs by 30-50% over time.

    Energy Ratings

    In the UK, windows are rated on the Window Energy Rating (WER) scale from A++ to E, with A++ being the most energy efficient. When selecting windows, look for:

    • A high WER rating (A+ or above for best performance)
    • Low U-values (measure of heat loss) – the lower the better
    • Appropriate solar gain (g-value) for your specific needs and climate

    By considering these factors, you can choose thermally efficient windows that best suit your home’s needs and your budget while maximising energy savings.
