Cold windows, drafts, and frosty air even when heating is on are familiar to many. But there is a simple way to make rooms cozier — and it doesn’t require any renovations.
How Curtains Help Retain Heat
Even modern windows allow cold air to pass through, and microcracks increase heat loss. Closed curtains, blinds, or films create an additional barrier that reduces the flow of cold air and helps save on heating.
Advantages of Closed Curtains:
- Heat Retention: Thick fabrics and panels create an insulating layer, reducing the load on radiators.
- Fewer Drafts: Closed curtains minimize the entry of cold air through gaps.
- Reduced Costs: Properly selected thermal curtains can decrease heating bills by 10–20%.
- Protection Against Condensation and Mold: Curtains and insulating films help maintain a stable temperature, preventing moisture on the glass.
Best Ways to Insulate Windows
- Thermal Curtains: Retain warm air between the window and the fabric. Close them at night or on cold days.
- Roller and Cellular Shades: Create air pockets that further insulate the room.
- Plastic Window Film: An airtight layer of air, easily attached by yourself with double-sided tape and a hairdryer.
- Bubble Wrap: A budget-friendly and quick option for retaining heat on the glass.
Mistakes to Avoid
- Closing curtains during sunny weather.
- Completely ignoring windows and gaps.
- Covering radiators with curtains — this blocks the flow of heat into the room.
- Using curtains that are too short or narrow.
Closed curtains in winter are not just a decorative element, but a real way to retain warmth and coziness. For maximum effect, combine them with sealing gaps and proper air circulation.
