Frequently Asked Questions
Q: What window types is this portable AC window seal kit compatible with?
A: This AC window seal kit is designed to work with most standard single-hung and double-hung windows commonly used with portable air conditioner exhaust hose setups. Simply measure your window gap and select the appropriate size (25×100 cm, 25×180 cm, or 25×250 cm) for the best fit.
Q: How does the 3-layer construction improve insulation compared to a single-layer seal?
A: The three layers work together for superior thermal performance: the aluminum film reflects radiant heat from sunlight, the cotton fill provides cushioning and insulating bulk, and the Oxford cloth exterior resists wear and moisture. Together, they block warm outdoor air far more effectively than a basic single-layer foam or plastic panel.
Q: Is this window seal reusable between seasons?
A: Yes! The durable Oxford cloth and aluminum film construction is built to last multiple seasons. Simply fold the seal flat for compact storage during winter months and reinstall it each summer when you bring out your portable AC unit.
Q: Do I need any tools or adhesives to install this AC window seal?
A: No tools or permanent adhesives are required. The seal is designed to fit snugly within your window frame alongside your portable AC's window panel kit. It's a completely tool-free, damage-free installation that can be done in minutes.
