Preventing Those Winter Chills

5 Signs Of A Drafty Window

As the winter winds start to whistle through the trees, there’s nothing cozier than being snug in your home, protected from the elements. However, if you notice an unexpected chill, especially near your windows, you might be dealing with drafts. Drafty windows not only make your home less comfortable but can also significantly impact your energy bills. In this guide, we’ll unravel the mystery of drafty windows, explore how to identify them, and discuss effective ways to prevent those unwanted chills.

Signs of Drafty Windows

1. Temperature Variations:

  • One of the most apparent signs of drafty windows is feeling a noticeable drop in temperature when you’re close to them.
  • Use a handheld thermometer to compare the temperature near windows with the rest of the room.

2. Deteriorating Sealant:

  • sealant is a clear sign of aging, which can lead to drafts.
  • Reapply caulking or weather-stripping where needed to ensure a tight seal.

3. Visual Inspections:

  • On a windy day, carefully inspect your windows for any movement. Even a slight flutter of curtains or blinds can indicate air leaks.
  • Shine a flashlight around the window frame at night. If you notice light seeping through, it’s a sign of gaps that need attention.

4. Rattling Windows:

  • If your windows rattle even when closed, it suggests poor insulation. This can be a result of worn-out weather-stripping or damaged components.

5. Energy Bills Spike:

  • Keep an eye on your energy bills. A sudden increase could be due to your heating system working overtime to compensate for drafts.

5 Ways To Prevent Drafts

1. Seal Gaps and Cracks:

  • Use weather-stripping to seal gaps around windows. This flexible material comes in various forms, including adhesive-backed foam and V-strip.
  • For larger gaps or cracks, consider using caulk. Silicone or acrylic caulk is effective and easy to apply.

2. Install Window Film:

  • Window film adds an extra layer of insulation. It’s a cost-effective solution that can be applied directly to the glass surface.
  • Choose insulating window films designed to reduce drafts and heat loss.

3. Upgrade Window Treatments:

  • Heavy curtains or cellular shades provide an additional barrier against drafts. Ensure they reach the windowsill or floor for maximum effectiveness.
  • Layering window treatments, like using blinds with curtains, can enhance insulation.

4. Consider Draft Stoppers:

  • Draft stoppers, also known as draft snakes, are fabric tubes placed at the bottom of doors and windows to block cold air.
  • You can purchase these or easily make your own using fabric and filling material.

5. Invest in Energy-Efficient Windows:

  • If your windows are outdated, upgrading to energy-efficient models can significantly reduce drafts.
  • Look for windows with multiple panes, low-emissivity coatings, and insulating gas between the panes.
