Get Ready for Winter: How Your Windows Make All the Difference
With winter approaching, it’s important to consider how well your windows are keeping the heat in. Old or inefficient windows can allow warmth to escape, leading to draughts, rising energy bills, and a home that’s harder and more expensive to heat.
At Custom Glaze, we specialise in installing high-quality, energy-efficient ‘A+’ rated windows designed to lock in warmth and keep the cold out. Whether you’re replacing single glazing or upgrading older units, our windows help create a warmer, drier, and more efficient home, just in time for the colder weather.

Why Windows Matter More in Winter
During winter, your windows are one of the first places where warmth can escape. If you’re noticing chilly spots near your windows, fogged-up glass, or even visible condensation, your windows might be letting that heat out of your home.
Modern, high-quality windows help to:
– Retain heat more effectively
– Reduce condensation
– Minimise draughts
– Lower energy bills
Homes with single-glazed or older double-glazed windows should consider upgrading before the cold weather sets in. Taking action now will help prevent heat loss and reduce energy costs as temperatures drop.
Prevent Condensation Before It Starts
Condensation occurs when warm, moist air from inside your home meets the colder surface of your windows, at which point it cools rapidly and turns into water droplets. This is particularly common in winter when there is a greater difference between indoor and outdoor temperatures.
It can also be a sign of poor insulation and ventilation, leading to bigger problems like damp, mould, and damage to your window frames.
Tips to reduce window condensation:
- Control indoor humidity with extractor fans or a dehumidifier
- Open trickle vents to allow air flow, even when windows are closed
- Improve air circulation by moving furniture away from windows
- Upgrade to modern double glazing with built-in ventilation systems.
At Custom Glaze, all our windows come with advanced weather seals and energy-efficient glazing, helping to keep winter condensation away.

Insulate and Seal Your Windows
Properly insulated windows can make a huge difference to your comfort in winter. Especially when even small gaps can let in draughts, causing you to use more heating than is necessary.
How to improve window insulation:
- Check for gaps or cracks around the window frame and seal with caulking
- Replace worn-out or missing weatherstripping
- Use thermal curtains or blinds for extra insulation
- Consider installing secondary glazing if replacing isn’t an option.
For a long-term solution, modern double or triple-glazed units with multi-chambered frames provide far better insulation compared to older models.

Time to Upgrade?
If your windows are constantly fogged up, draughty, or difficult to open and close, it’s likely time for a replacement. Upgrading your windows before winter means:
- Warmer indoor temperatures
- Lower heating bills
- Less condensation
- Improved home security
- Higher property value.
At Custom Glaze, our uPVC and aluminium windows are designed to meet the latest building regulations, including integrated ventilation for better air quality without losing warmth.
