Why Your Windows Are the Biggest Factor in Winter Energy Efficiency
When winter hits the UK, most homeowners turn up the thermostat, close the curtains, and hope their heating system keeps up. But the real issue is often not the boiler — it’s the windows.
Across St Helens and the North West, thousands of homes lose a significant amount of heat through old, inefficient, or poorly installed windows. This leads to higher heating bills, colder rooms, and more energy use than necessary.
At DaveStyle Windows, Doors & Conservatories, we’ve spent more than 20 years helping homeowners transform their homes with modern, A-rated glazing that keeps the heat in and the cold out. Here’s why your windows are the single biggest factor in your home’s winter energy efficiency.
1. Windows Are the Main Source of Heat Loss in UK Homes
According to UK energy studies, up to 40% of heat loss can occur through windows alone — especially if they are:
- Old aluminium frames
- Single-glazed
- Early double glazing
- Damaged or misted
- Poorly sealed around the edges
When warm air escapes, your heating system works harder, for longer, costing you more every month.
Modern windows significantly reduce this problem through advanced insulation and airtight seals.
2. Modern Windows Use Low-E Glass to Retain Warmth
One of the biggest scientific improvements in window design is Low-Emissivity glass.
What Low-E glass does:
- Reflects heat into your home
- Reduces heat transfer
- Helps maintain stable temperatures
- Keeps your rooms warmer for longer
This invisible coating is a game-changer for winter warmth and is included in all DaveStyle A-Rated window installations.
3. Draughts Are Silent £££ Killers — And Windows Are the Main Culprit
Draughts are one of the most overlooked sources of heat loss in UK homes.
If you feel cold air around your windows in winter, you're losing money.
Common causes include:
- Shrinking old seals
- Gaps in poor installations
- Warped frames
- Worn glazing beads
DaveStyle windows use:
- High-performance seals
- Multi-point locking
- Precision installation techniques
This eliminates draughts and helps homeowners across St Helens enjoy a warmer, more comfortable winter.
4. Double & Triple Glazing Technology Reduces Heat Transfer
Modern double and triple-glazed windows use argon gas-filled units, which act as a thermal barrier between panes.
Why argon gas matters:
- It slows down heat movement
- Reduces cold transfer through the glass
- Keeps the inner pane warmer
- Helps retain more indoor heat
Combined with warm-edge spacer bars, this technology dramatically improves winter energy efficiency.
5. Insulated UPVC Frames Stop Heat Escaping Through the Edges
Heat doesn’t just escape through the glass — it also escapes through the frame.
Modern UPVC frames installed by DaveStyle are engineered with:
- Multi-chamber insulation
- Reinforced thermal barriers
- Energy-efficient internal design
These chambers trap air inside the frame, which reduces heat loss and helps stabilise indoor temperatures.
Older wooden or aluminium frames simply can’t compete.
6. Improving Windows Improves Your Entire Home’s Energy Rating
Your EPC (Energy Performance Certificate) rating is heavily influenced by:
- Heat loss
- Insulation
- Glazing performance
- Draught-proofing
Upgrading to A-rated windows has a direct positive impact on your EPC score, which means:
✔ Lower energy bills
✔ Higher property value
✔ Better comfort
✔ Reduced carbon footprint
This is one of the reasons so many St Helens homeowners are turning to DaveStyle before winter arrives.
7. New Windows Save Money Every Winter — Year After Year
Once installed, modern windows begin delivering savings immediately by:
- Reducing heating usage
- Helping rooms heat up faster
- Retaining warmth longer
- Reducing reliance on electric heaters
- Lowering boiler workload
Over time, the savings add up — and with rising UK energy prices, the investment becomes even more valuable.
