Do you ever sit near your window on a cold evening and feel a chill creeping in? You might think it is just the weather. But the truth is, your windows could be the problem. Old or single-glazed windows let warmth escape from your home far more than most people realise. The good news? There is a simple, effective solution — and homeowners across the south coast are already benefiting from it.
How Heat Escapes Through Your Windows
Glass is a poor insulator. When cold air sits outside your window, it pulls the warmth from inside your home through the glass. This process is called heat transfer, and it happens constantly during the colder months.
There are three main ways your windows lose heat:
Conduction — Heat passes directly through the glass from the warm side (inside) to the cold side (outside). Single-glazed windows do almost nothing to slow this down.
Draughts — Old window frames crack, warp, and lose their seal over time. This lets cold air sneak straight into your home around the edges.
Condensation — If you notice water droplets forming on the inside of your glass, that is a sign your windows are struggling to hold heat. It also leads to damp and mould over time, which is bad for your home and your health.
If your heating is always running but your rooms still feel cold, your windows may be to blame.

What Makes Double Glazing Different?
Double glazing works by using two panes of glass instead of one, with a small gap between them. That gap — usually filled with argon gas — acts as a barrier. It slows down heat transfer significantly, keeping warmth inside where it belongs.
Here is why it makes such a big difference:
- Better insulation — The two-pane design traps heat inside your home, so your boiler does not have to work as hard.
- No more draughts — Modern double-glazed frames are sealed tightly, blocking cold air from creeping in around the edges.
- Less condensation — Because the inner pane stays warmer, you get far less moisture build-up on your glass.
- Lower energy bills — When less heat escapes, you spend less money keeping your home warm. Many households notice a real difference on their energy bills.
- Quieter home — As a bonus, double glazing also reduces outside noise, which is great if you live near a busy road.
Is It Worth It for Homes in Eastbourne?
Absolutely. Eastbourne might enjoy plenty of sunshine, but winters on the East Sussex coast can be cold and breezy. Homes in the area — especially older terraces and period properties — often have ageing windows that do very little to keep the cold out.
