Enhanced Thermal Efficiency

ecoslience windows and doors are designed to deliver outstanding energy efficiency, consistently outperforming standard alternatives. While the average double glazed window in the UK has a U-value of around 1.4 W/m²K, ecoslience can achieve impressive U-values as low as 0.66 W/m²K. This means ecoslience products can be up to twice as efficient as typical industry standards, helping to retain more heat inside your home and create a consistently comfortable living environment. With ecoslience, you’ll rely less on central heating and air conditioning, leading to noticeably lower energy bills. Over time, this can add up to savings of up to £15,000 across 35 years. Reduced energy use also means lower emissions, making ecoslience a smart choice for both your finances and the environment.
