Reduce window draughts: The Practical Fix Most Homes Miss
If your home feels chilly even when the heating is on, the issue is often not your boiler or radiators. It is the constant movement of cold air around your windows. Reduce window draughts and you usually improve comfort immediately, because you are tackling the source of that cold “pull” you feel near glass and frames. The problem is that many homeowners focus on thicker curtains or turning the thermostat up, rather than fixing the gaps and cold-bridging routes that let heat escape in the first place.
At ThermaShutter, based in Essex, we build the next generation of heat-saving shutters in Britain. Our shutters are engineered for the UK climate: cold winters, damp conditions, and real homes that need both performance and style. With insulated ThermaCore construction and a complete perimeter seal, we help reduce draughts, stabilise room temperature, and cut cold spots you can often see on thermal imaging.
Reduce window draughts: why windows feel chilly even when they are “closed”
Most people assume a closed window is airtight. In reality, even modern windows can allow small air paths around the frame, trickle vents, seals that have compressed over time, or slight installation tolerances. Older properties can be worse, but newer homes are not immune.
Two issues are normally at play:
Air leakage (draughts)
Small gaps allow cold air to move into the room and warm air to leak out. You might notice whistling in high winds, or a constant cool sensation along the sill.
Cold bridging and cold surfaces
Even without a strong draught, the area around the window can become much colder than the rest of the room. That cold surface cools the nearby air and makes the whole space feel less comfortable.
This is why quick fixes can disappoint. Heavy curtains can reduce direct airflow, but they do not seal the perimeter. Foams and tapes can help temporarily, but they often look untidy and do not address the window area as a complete system. The practical fix most homes miss is combining insulation with a proper perimeter seal and a structured barrier that closes consistently.
Reduce window draughts with a perimeter seal, not just thicker coverings
If you want a meaningful improvement, focus on the edges. Heat does not only escape through the glass; it also travels through the surrounding structure and leaks around the frame where air movement happens. That is why a perimeter seal matters.
ThermaShutter shutters are engineered as a complete thermal system. Our upgraded external frame includes a thermal neoprene draught excluder designed to:
Block cold drafts around the frame
Stop warm air leaking from the edges
Reduce cold bridging from the surrounding structure into the shutter frame
Improve overall comfort, not just “look warmer”
This matters because it changes the way the room behaves. Instead of warm air rising, cooling at the window, and circulating back into the room, you create a more stable boundary at the window line. It is the difference between a room that looks finished and a room that actually feels warmer.
Reduce window draughts in Essex homes with insulated shutters built for the UK climate
Insulation is the second half of the solution. Many shutters on the market are decorative, lightweight, or imported systems without proven UK-specific performance. They may look good, but they are not designed to act as a thermal barrier.
ThermaShutter shutters are British-made using moisture-resistant composite reinforced with insulated polymer. They are engineered to resist the issues that frustrate homeowners over time: warping, swelling, fading, and poor long-term fit. The insulated core gives a denser construction, and that density supports better thermal performance and a more premium feel.
We also design shutters to suit how people actually live:
Full height shutters for maximum warmth and full window coverage
Tier-on-tier shutters for flexible privacy and daylight control
Café style shutters for light-filled rooms with privacy at eye level
The best style depends on the room, the level of exposure, and how you use the space. Bedrooms and street-facing living rooms often benefit most from full height coverage. Kitchens and dining rooms often favour café style for brightness, while tier-on-tier is popular where privacy and daylight need to be balanced throughout the day.
What a thermal imaging survey tells you
It is one thing to claim results. It is another to show them. That is why every home can be assessed with a before-and-after thermal imaging survey, giving you visible evidence of what is happening around your windows.
Thermal imaging can highlight:
Heat leaking through glazing
Cold bridging around the frame and surrounding structure
Cold patches that correlate with draught routes
Areas where a sealed shutter system can improve stability
It also helps you prioritise. Some homes have one or two windows that cause most of the discomfort. Others have a pattern across front elevations, bay windows, or large openings where a fitted system provides the biggest improvement.
Frequently asked questions
Are shutters better than curtains for draughts?
Curtains can help, especially when fitted well, but they rarely create a consistent perimeter seal. A fitted shutter system is typically more effective for controlling airflow at the edges.
Will shutters work in kitchens and bathrooms?
Yes, as long as the materials are suitable. ThermaShutter uses moisture-resistant construction designed for damp conditions common in UK homes.
Do shutters make rooms darker?
You control this through louvres and panel styles. Tier-on-tier and café style options are popular for maintaining daylight while improving privacy.
