Nedis ACWS4M air conditioner accessory Window sealing

The Nedis ACWS4M air conditioner accessory Window sealing is a polyester window gasket designed to create a sealed passage for portable air conditioner hoses or vents. Manufactured in white, this flexible sealing strip measures 4000 mm in width and 400 mm in depth, providing an extended coverage area to fit larger window openings or to overlap window frames for improved sealing and draft reduction.

Advantages

This window sealing is made from durable polyester that resists wear and maintains flexibility over repeated installations. Its 4-metre width allows installation across wide windows or sliding doors without the need for multiple sections, and the 400 mm depth offers sufficient overlap to accommodate most exhaust hoses and adapters. The white finish provides a neutral appearance that blends with typical window frames and interior decor. The product is lightweight, easy to handle and can be trimmed or adjusted on site to match specific window shapes.

Suitable for

• Sealing around portable air conditioner exhausts in residential rooms
• Temporary or seasonal installation in apartments and offices
• Creating a sealed opening for air-to-window adapters and ventilation ducts
• Reducing drafts and improving cooling efficiency of portable AC units

How to use

Measure the window opening or sliding door where the portable air conditioner exhaust will pass. Cut the polyester sealing strip to the required length if necessary. Position the sealing strip so that it covers the gap around the exhaust hose and overlaps the window frame to form a continuous barrier. Secure the sealing at the frame using compatible fasteners, adhesive tapes or clamps suitable for polyester and the window material, ensuring a snug fit without obstructing the hose. Verify that the exhaust hose can move freely and that the sealing provides an adequate seal to minimize air leakage.

Usage recommendations

For best results, clean the window frame surface before installation and use weather-resistant adhesive tape or mounting products that are compatible with polyester and the window material. Trim excess material carefully and check the seal periodically for wear, especially if the installation is left in place for an extended season.
