Considering replacement windows?

Energy efficiency & cost savings

The installation of double glazing, also known as double-pane windows, is a significant upgrade for both new and existing homes due to its substantial impact on energy efficiency and cost savings. Energy Efficiency and Heat Loss Reduction:

  • Double-glazed windows are known for reducing heat gain and loss through windows, which account for 25%–30% of residential heating and cooling energy use.
  • They incorporate two glass panes with a space filled with gas, like krypton or argon, which forms a thermal barrier, significantly reducing heat transfer compared to single-pane windows.

Cost Savings:

  • Upgrading to double-pane windows can lead to an average energy savings of up to 12% per year. This reduction in energy usage directly translates to lower utility bills.
  • In the context of rising energy costs, anticipated to increase by as much as 23% double glazing can help offset these higher expenses.

Additional Benefits: Beyond energy efficiency, double glazing works well for any home offers several other advantages:

  • Noise Reduction: The air gap between the glass panes acts as a sound buffer, significantly reducing outside noise.
  • Improved Comfort: These windows prevent drafts and temperature fluctuations, ensuring more consistent indoor temperatures. Double glazing can be utilised in winter months for these very reasons.
  • Durability: Double-glazed windows tend to have a longer lifespan, often lasting significantly longer than single-pane windows before needing replacement.
  • Increased Resale Value: Energy-efficient updates like double-glazing are attractive to home buyers, potentially increasing a home’s value by up to 8%.

Selection Tips for Double Glazing: When selecting double-glazed windows, it’s important to consider several factors:

  • Frame Types: Different materials offer varying levels of insulation and durability.
  • Glazing Type: Select appropriate glazing based on your climate, opting for gas-filled windows with low-e coatings in colder climates to reduce heat loss.
  • U-Factor: This measures the window’s thermal resistance. A lower U-factor is better in colder climates.
  • Solar Heat Gain Coefficient (SHGC): A lower SHGC is preferable in warmer climates to reduce heat gain.

Investment and Incentives:

  • The average cost of double-pane windows ranges from £300 to £5,500, depending on various factors like size, material, and features.
  • Upgrading to double glazing can qualify for renewable energy tax credits of up to £500 per window, providing further financial incentives.

In conclusion, double glazing is not only an efficient way to enhance the energy performance of a building but also a financially savvy investment. With benefits ranging from reduced energy bills to improved comfort and increased property value, it’s a highly recommended upgrade, especially in the context of escalating energy costs.

Investing in double glazing windows in the summer months helps regulate heat, as well as protect interiors from strong UV rays.

Reducing energy bills

One of the most compelling reasons to choose double glazing is the potential for energy savings. By providing better insulation, double-glazed windows reduce the need for heating in winter and air conditioning in summer, leading to lower energy bills.

Deep Dive into Thermal Insulation

How does double-glazing prevent heat loss?

Double glazing prevents heat loss through its insulated glass units, which consist of two panes of glass separated by a spacer and sealed to prevent air and moisture ingress.

The Role of Inert Gases

The space between the two panes of glass is filled with an inert gas, usually argon, which acts as an insulator, further preventing heat transfer.
