Windows play a significant role in a property’s energy efficiency. Upgrading your windows can lead to better insulation, reduced heat loss, and consequently, an improved Energy Performance Certificate (EPC) score. Here’s how window upgrades can help enhance your EPC rating and what options to consider.
Why Windows Affect EPC Scores
Windows are often a major source of heat loss in homes, especially if they are old, single-glazed, or poorly sealed. Energy-efficient windows reduce drafts, prevent heat escape, and improve overall comfort — all factors considered in your EPC assessment.
Window Upgrade Options to Boost EPC Ratings
1. Double Glazing
Installing double-glazed windows with two panes of glass separated by a spacer filled with air or inert gas significantly reduces heat loss compared to single glazing.
2. Triple Glazing
Triple glazing adds a third pane, further improving insulation and noise reduction, ideal for colder climates or noisy urban areas.
3. Low-E Glass
Low-emissivity (Low-E) glass has a special coating that reflects heat back into the room, improving thermal performance without compromising natural light.
4. Window Frames
Energy-efficient frames made from uPVC, timber, or composite materials with good sealing can prevent drafts and thermal bridging.
5. Proper Installation and Sealing
Even the best windows lose efficiency if poorly installed. Ensure professional fitting and weatherproof sealing to avoid leaks.
Additional Benefits of Window Upgrades
Reduced energy bills due to less heating demand
Increased property comfort and noise reduction
Enhanced property value and curb appeal
