This air conditioning window kit allows for easy installation of a portable air conditioner in any window opening. It provides an effective seal while allowing the exhaust hose to pass through. Ideal for homes without a fixed air conditioning system. Made of lightweight and durable PVC, this air conditioning window kit withstands heat, hot airflow, and temperature variations over time – without deforming or premature aging. Adjustable panels (up to 43 cm) fit most sliding or hinged windows. Quick installation without special tools – just the included screws. Includes a universal adapter compatible with most portable air conditioner hoses (standard diameter), as well as sealing tape to prevent air leakage. Complete contents: 4 PVC window panels (43 cm each), 1 universal adapter, 1 roll of sealing tape, 4 sets of mounting screws – ready to be installed immediately. This air conditioning window kit is designed to complement the use of a portable air conditioner in a home or commercial environment. Made of lightweight but rigid PVC. It guarantees stability and longevity even with repeated thermal exposure. The panels are fully adjustable in width (max. 43 cm) and compatible with standard windows (sliding, hinged, or tilt-and-turn windows). The universal adapter facilitates the passage of the exhaust hose without compromising the seal. The included tape reinforces insulation around the joints. No structural modifications required: quick installation and removal without damage to the window frame. This air conditioning window kit is suitable for private homes, tenants, and temporary professional spaces (offices, meeting rooms, studios).
