Want Better Home Energy Savings? Weatherize Your Windows

San Antonio may not be the coldest place on earth in the winter, but you can still save a considerable amount of money on heating bills — and cooling costs — by weatherizing windows in your home.

Air leaks in your home’s envelope allow unconditioned air to infiltrate and conditioned air to escape outside. This taxes the HVAC system as it works overtime to keep your home comfortable, and it costs you in energy dollars and reduced comfort.

Weatherizing Windows is Easy and Inexpensive

All you need to weatherize windows are a few inexpensive items and a free afternoon. Before you begin, gather your supplies:

  • Silicone caulk.
  • Rope caulk.
  • Expandable foam if you have large gaps and cracks around your windows.
  • Adhesive-back weatherstripping.
  • Window insulation kits.

Caulking is simple, but be sure to read the directions for use if you’ve never worked with these products.

Start With the Exterior

Inspect the exterior windows for large gaps and cracks around the casing, and fill these with expandable foam. Apply silicone caulk to the seam between the window frame and the exterior of the house. If you have storm windows, install them.

Seal Your Windows Indoors

Weatherizing windows inside your home is easy. Just as you did outside, caulk the seam where the window frame meets the wall. Open the windows, and install the weatherstripping at the top and bottom to keep air out. Use the removable rope putty to seal the movable seams around the windows.

If you don’t have storm windows, or if your house is particularly old, use window insulation kits to install shrinkable plastic film over the windows. This air-tight barrier will offer a high level of comfort in draftier rooms.

Consider an Energy Audit

Windows aren’t the only culprit when it comes to air leaks. Baseboards, recessed lighting fixtures, and pipe and service entrances can send your energy bills through the roof. A professional home energy audit helps pinpoint the exact locations of air loss in the home.
