Insulation hacks to boost energy efficiency don’t require a full-scale renovation. Make your home more energy efficient with a few affordable DIY insulation tricks. You can reduce drafts, keep your home more comfortable, and save on utility bills, all without tearing down walls. Here are some easy ways to get started:

 
  1. Seal Gaps with Weatherstripping
    Apply adhesive weatherstripping around windows and doors to block out drafts. It’s inexpensive, easy to install, and makes a noticeable difference in both winter and summer.
  2. Use Door Sweeps and Draft Stoppers
    Install door sweeps on exterior doors or use fabric draft snakes to stop cold air from creeping in underneath.
  3. Insulate Windows with Plastic Film Kits
    Window insulation kits create a barrier over windows that helps trap heat inside during the colder months. A hairdryer seals the film in place for a snug, invisible finish.
  4. Add Foam Gaskets Behind Outlet Covers
    Exterior wall outlets can let in surprising amounts of air. Installing foam gaskets behind the faceplates helps insulate these small but drafty spots.
  5. Cover the Attic Hatch
    Your attic access point can be a major energy leak. Add insulation and a weatherstrip seal to the hatch to keep conditioned air from escaping.
  6. Hang Thermal Curtains
    Thick, insulated curtains can dramatically reduce heat loss through windows, especially in older homes with single-pane glass.
These small steps can add up to a cozier home and noticeable energy savings — all without a major or minor renovations.
