Window seal for air conditioner Nedis ACWS6M — foam gasket for through-window AC installation

Window seal Nedis ACWS6M is a foam gasket designed to fit around through-window air conditioner hoses and housings to reduce drafts, dust and light infiltration. The product creates a continuous insulating barrier between the appliance and the window opening, improving thermal and acoustic sealing for portable or through-window air conditioning units. It is intended for temporary or semi-permanent installations where a neat, compressible seal is required.

Advantages

The foam construction adapts to irregular window frames and various hose diameters, providing a flexible seal without the need for custom cutting. The material offers thermal insulation and helps reduce noise transfer, while also limiting the entry of dust and insects. Installation does not require specialist tools, and the gasket can be repositioned or removed when the air conditioner is not in use.

Suitable for

• Portable air conditioners with exhaust hoses passing through a window opening
• Through-window AC units where the housing creates gaps around the frame
• Temporary or seasonal AC installations in apartments, offices or holiday homes
• Situations requiring improved insulation against drafts, dust and light

Key specifications

• Material: compressible foam designed for sealing applications
• Function: fills gaps between air conditioner hose or housing and window frame
• Performance: provides thermal and acoustic sealing suitable for temporary or semi-permanent use
• Compatibility: suitable for a variety of window types and hose diameters due to flexible construction
• Installation: tool-free fitting, repositionable and removable

How to use

Measure the gap around the air conditioner hose or housing where it passes through the window and cut the foam gasket to the required length if necessary. Compress the gasket and position it around the hose or between the appliance housing and the window frame so that it creates continuous contact with both surfaces. Ensure the foam is seated along the full perimeter of the opening to form an effective barrier. Remove and store the gasket when the unit is not in use or when a permanent installation is planned.

Usage recommendations

For best results, clean the window frame and surrounding surfaces of dust and debris before fitting the gasket to improve contact and sealing performance. Avoid exposing the foam to open flames or sharp objects, and check the seal periodically for wear or compression that could reduce effectiveness.
