Our take on the Duck Brand 2.25 Inch X 2.25 Inch X 42 Inch Window Air Conditioner Insulating Seal, Noise Reducing

This is a foam strip that fills the gap between a window air conditioner and the window frame. It blocks outside air, dust, insects and pollen, and it dampens some of the noise and vibration the unit makes. It is a low-cost fix for drafty, rattling window units and suits renters and homeowners who want a quick seal without reinstalling the A/C. Compared with generic foam tape, Duck's strip is cut to a size that fits most window units, and owners rate it highly for ease of use.

Questions and answers

Will it fit my window air conditioner?
The strip is 2.25 inches wide and 42 inches long, which covers the gap on most standard window units. Measure your gap and trim as needed.
Does it really reduce noise?
It dampens vibration and rattling by cushioning the unit against the frame. It will not silence the compressor or fan.
Can I use it on a sliding window or door?
It is made for the gap around a window A/C unit. It can also seal similar gaps on other window frames if trimmed to fit.
How do I install it?
Clean and dry the frame, peel the backing and press the foam into the gap between the unit and the frame. Cut to length with scissors.
Will it leave residue when removed?
The adhesive can leave some residue on painted or rough surfaces. Warm soapy water usually cleans it off.
