Rising energy prices mean homeowners are more aware than ever of where heat is escaping from their property. And one of the biggest culprits? Inefficient windows.
Windows make up around 20% of a home’s heat loss. If yours are outdated or poorly fitted, you could be throwing away hundreds of pounds every year. At Finesse Windows, we design, manufacture and install energy-efficient windows that are built to last, but how do you know when your current windows are costing you? Here are seven warning signs to look out for.
1. Draughts You Can Feel
If you can feel a cold draught near your windows, even when they’re closed, heat is escaping. This usually happens when seals have perished, or the frame has warped over time. Draughts mean your heating system has to work harder, and that means bigger bills.
2. Condensation Between the Panes
Modern double glazing is sealed to keep moisture out. If you see condensation inside the unit, it’s a sign the seal has failed. That means the insulating gas has escaped and your windows are no longer performing as energy-efficient units should.
3. Cold Spots and Rooms That Won’t Stay Warm
Do you find some rooms are always colder than others, no matter how high you turn up the thermostat? Old or single-glazed windows allow significant heat loss through the glass and frames. Upgrading to modern upvc windows from Finesse Windows (add Homepage link) with advanced insulating glass can transform comfort levels and reduce wasted heat.
4. Rising Energy Bills With No Clear Reason
If your heating usage hasn’t changed but your bills keep climbing, it could be down to hidden energy loss. Windows that look fine on the surface may still be underperforming if they don’t meet current A-rated energy standards
5. Difficulty Opening or Closing Windows
Windows that have swollen, warped or dropped can create tiny gaps around the frame. These gaps allow warm air out and cold air in. At Finesse, our frames are steel-reinforced and designed to maintain shape over decades. If yours are difficult to operate, they’re likely costing you energy as well as convenience.
6. Noise From Outside
This isn’t just about peace and quiet, it’s also about insulation. If you can clearly hear traffic or neighbours through your windows, chances are they’re not holding in heat either. Our Shield glass and acoustic options improve both warmth and sound insulation.
5. Windows Over 20 Years Old
Even if your older double glazing seems fine, technology has moved on. Modern Finesse windows include multi-point locks, warm-edge spacers, low-E coatings and argon-filled glass as standard. Older windows simply can’t compete on energy performance.
