What’s Inside the Kit?
Your kit includes helpful materials commonly used to seal and insulate draft‑prone areas:
- Weatherstripping: Helps reduce drafts around doors and windows
- Door sweep: Closes gaps at the bottom of exterior doors
- Foam outlet/switch gaskets: Prevent air leaks through electrical plates
- Window film: Adds an extra insulating layer to older windows
- Caulk or gap filler: Seals cracks and small openings around trim or fixtures
- Simple instructions: Step‑by‑step guidance to complete each task
Why Weatherization Matters
Small air leaks can add up, making your home harder to cool in the summer and heat in the winter. The improvements in this kit help:
- Lower energy bills by preventing conditioned air from escaping
- Improve temperature consistency across rooms
- Reduce strain on heating and cooling equipment
- Increase overall home comfort
Where to Use Your Kit
Here are the most common places customers find the biggest benefits:
- Doors & Windows: Seal gaps along edges, frames, and thresholds.
- Electrical Outlets on Exterior Walls: Install gaskets behind plates to stop cold or warm drafts.
- Baseboards & Trim: Caulk cracks where walls meet flooring or window frames.
- Older Windows: Apply clear insulating film to help keep conditioned air inside.
Tips for Best Results
- Clean surfaces before applying adhesive materials.
- Use a hairdryer to shrink window film for a smooth finish.
- Check all exterior doors for light coming through, that’s where weatherstripping helps most.
- Combine improvements for greater savings.
