Frequently Asked Questions
Q: What window types is this portable AC window seal compatible with?
A: This AC window seal kit is designed to work with most sliding, casement, and double-hung windows. The flexible soft cloth material and adhesive strips allow it to conform to a wide variety of window frame shapes and sizes, making it suitable for home, office, and rental use.
Q: Will the adhesive damage my window frame when removed?
A: The no-drill adhesive installation is designed to be rental-friendly and to minimise surface impact. For best results, remove the seal slowly and clean any adhesive residue with a mild cleaner. It is always advisable to test on a small inconspicuous area first, particularly on painted or coated surfaces.
Q: What is the difference between the 3-metre and 4-metre options?
A: Both options feature double slider zippers and the same high-quality sealing soft cloth material. The 3-metre length suits standard windows, while the 4-metre option is ideal for wider windows or sliding glass doors where additional coverage is needed to fully seal around the portable AC hose.
Q: Can this seal be used in winter as a draft stopper?
A: Yes! The waterproof and windproof construction means this window seal functions effectively as an all-season draft stopper, helping to maintain consistent indoor temperatures whether you're running cooling in summer or keeping warmth in during colder months.
