300cm Flexible AC Window Sealing Kit

A 300 cm flexible window sealing solution made from water-resistant nylon, designed for easy adaptation to varied UK window types—including sash, casement, and French doors. Its dual-hole configuration accommodates standard portable AC exhaust hoses up to 150 mm in diameter, with a central zip for precise sizing and industrial-grade adhesive for firm attachment to smooth or textured window frames. The material remains supple in cool mornings and stable in midday heat, supporting repeat use without curling, peeling, or loss of tackiness.
