How to Dispose of Weatherstripping
- 1Self-adhesive weatherstripping foam tape, brush pile mohair draft seals, rubber sash strips, and zippered plastic draft shield curtains are non-recyclable composite wastes contaminated with adhesive glues and mixed resins.
- 2Never place them into plastic or textile recycling bins; discard them 100% inside standard municipal general waste bags (Jongnyangje).
- ✓Separate any steel pushpins or staples for scrap metal disposal, and clean sticky residue remaining on window sashes using adhesive remover or rubbing alcohol with a plastic scraper.
How to Dispose (5 Steps)
- 1
Peel off old weatherstripping & draft shield film: Slowly pull degraded, discolored plastic insulation film and self-adhesive foam tape away from window sashes and doorframes.
- 2
Separate metal pushpins and staples: Use pliers to remove all steel thumbtacks or staple gun pins and sort into scrap metal; never toss exposed sharp pins into plastic trash bags.
- 3
Discard brush pile mohair & foam seals in general waste: Pile weatherstripping combines nylon bristles, rigid plastic rails, and industrial glue into a non-recyclable composite; discard all foam and rubber draft seals into standard general trash bags.
- 4
Remove sticky adhesive residue from window sashes: Spray adhesive remover or apply rubbing alcohol to stubborn glue residues on PVC sashes, wait 5 minutes, and scrape cleanly using a plastic putty knife.
- 5
Verify clean plastic film vs. adhesive-contaminated sorting: Pure clean polyethylene sheets without tape, zippers, or Velcro can be recycled as plastic film; if any glue or fabric borders remain, discard entirely in municipal general trash bags.

Frequently Asked Questions
Q. Can brush pile mohair weatherstripping be recycled with textiles or clothing?
A. No. Mohair pile weatherstrip is an inseparable tri-layer composite composed of a rigid PVC rail, synthetic nylon bristles, and heavy industrial pressure-sensitive adhesive. It cannot be recycled as textile or plastic and must be discarded entirely in a standard municipal general trash bag (Jongnyangje).
Q. Why can't plastic window insulation film be tossed into vinyl recycling?
A. Draft shield curtains typically feature sewn-in plastic zippers, Velcro loop borders, and sticky double-sided mounting tapes. These adhesives and mixed components jam recycling extrusion machinery. Unless completely clean transparent film without any glue or borders is trimmed out, the curtain must be discarded in general trash.
Q. How do I remove hardened weatherstrip foam adhesive from window frames?
A. Warm the tape with a hair dryer on medium heat for 10–20 seconds to liquefy the adhesive bond, then push it off with a plastic scraper or credit card. For residual sticky film, apply rubbing alcohol, commercial adhesive remover, or cooking oil for 3–5 minutes before wiping clean with a microfiber cloth.
Q. Is it possible to store and reuse plastic draft shield curtains next winter?
A. Yes. Velcro-mounted draft curtains can be wiped clean with a damp cloth, thoroughly air-dried, folded neatly, and stored in a sealed ziplock bag for 2–3 seasons of reuse. However, if the PVC plastic has yellowed, hardened, or torn, replace it with fresh film to ensure optimal thermal insulation.
