5. Caulking and Weatherstripping
Sealing spaces around windows with caulk and using weatherstripping can considerably minimize drafts and avoid air leak. This is a low-priced method that can yield excellent outcomes.
6. Cellular Shades
These window treatments feature a honeycomb style that traps air, offering insulation. They come in numerous styles and colors, offering both functionality and visual appeal.
7. Thermal Curtains
Heavy, insulated drapes can also assist decrease heat loss. While not as reliable as other techniques, they can be a feasible choice for those searching for a momentary solution.
