What are French Windows?
French windows are a stylish and practical type of window design that originated in France and have become popular in homes across the UK. Unlike conventional single-pane windows, French windows consist of two matching panels, each set with large panes of glass, which are hinged on either side and open outward from the centre. This design allows both sashes to swing fully open, creating a wide and inviting opening that connects your interior living space directly with your garden or patio.
French windows are prized for their ability to let in abundant natural light, offer excellent ventilation, and provide unbroken views of the outdoors. They combine elegant aesthetics with versatile function, making them a fantastic choice for both traditional and modern homes.
How Can French Windows Help Your Home Be More Energy Efficient?
French windows, when double glazed, play a significant role in boosting your home's energy efficiency. The two panes of glass are separated by a gap filled with insulating gas such as argon, which acts as a barrier to reduce heat transfer. This design means less warmth escapes during the winter, helping to keep your home cosy and cutting down on heating costs. In summer, double glazed French windows help block out external heat, maintaining a cooler indoor environment.
Additionally, many modern French windows feature warm edge spacer bars and advanced weather seals. These components reduce cold spots around the edges of the glass, prevent draughts, and limit condensation inside your windows. With energy efficient French windows, your home stays comfortable throughout the year and you benefit from lower energy bills and a reduced carbon footprint, all while enjoying plenty of natural light.
