Weatherstripping Selection Guide
Door Weatherstripping
V-Strip (Tension Seal): Durable spring-metal or vinyl strips that fold into a V shape, ideal for the sides and top of doors.
Door Sweeps: Attach to the bottom of the door to seal the gap between door and threshold — aluminum with vinyl or rubber inserts.
Foam Tape: Self-adhesive closed-cell foam for irregular gaps around door frames, easy to install and replace.
Window Weatherstripping
Rubber Gaskets: Compression-fit rubber seals for casement and awning windows — long-lasting and weather-resistant.
Pile Weatherstrip: Soft brush-like strips for sliding windows and patio doors — reduces air infiltration without restricting movement.
Window Film Kits: Shrink-film insulation kits that create a dead air space for added insulation during cooler months.
