Finding the right weatherstripping for your doors and windows can be confusing — there are dozens of types and hundreds of products. Here’s what actually works for each application.
Best for Doors: Magnetic Weatherstripping
Magnetic door seals create the tightest possible seal. The magnetic strip adheres to the door frame and connects with a metal strike plate on the door (or vice versa). Originally developed for commercial refrigeration, residential versions now exist.
Best for: Exterior doors, especially in cold climates where air infiltration is a major concern.

Best for Windows: V-Strip (Tension Seal)
V-strip weatherstripping folds into a V shape that springs against the gap between window sash and frame. It’s the most durable window weatherstripping option and works on both double-hung and sliding windows.
Best for: Double-hung windows, sliding windows. Lasts 3-5+ years.

Best Door Sweep: Automatic Door Bottom
An automatic door bottom retracts when the door opens and drops down to seal when it closes. No dragging on carpet, no wearing out from friction.
Best for: Doors over carpet or uneven thresholds where standard sweeps drag.

Best Budget Option: Foam Tape
Self-adhesive foam tape is the cheapest and easiest weatherstripping to install. It compresses to fill gaps around doors and windows.
Trade-off: It’s the least durable option — plan to replace every 1-2 years. But at $3-5 per roll, the cost is minimal.

Best for Large Gaps: Silicone Weatherstripping
Silicone tubular weatherstripping handles larger gaps (1/4 inch+) better than foam or V-strip. It’s flexible, durable, and temperature-resistant.
Best for: Older homes with irregular gaps, doors that have settled, warped frames.

Best Window Insulation Kit: Indoor Window Film
Heat-shrink window film kits create a dead air space between the film and the glass, dramatically improving insulation on single-pane windows.
Best for: Single-pane windows in cold climates. Can reduce heat loss through windows by 50%+.

Our Recommendation
Doors: Start with a good door sweep and foam or silicone weatherstripping around the frame. Upgrade to magnetic weatherstripping for maximum efficiency. Windows: V-strip for operable windows, caulk for fixed frames, and window film kits for single-pane windows in winter.
