Our take on the Universal Window Air Conditioner Insulator Kit Side Insulated Foam Panel Air Conditioner Accessories

A cut-to-fit insulation kit for window air conditioners: EVA foam panels faced with aluminum foil that seal the gaps around a window unit. The foil reflects sun and heat, and the foam blocks drafts, dust and some noise. It fits units from 5,000 to 22,000 BTU and is trimmed to the window opening with a knife. Compared with purpose-made rigid side panels or a full window seal kit, it is generic and unbranded, so fit and finish depend on your own cutting. It suits renters and DIY installers who want a cheap seal without modifying the window.

About the Universal Window Air Conditioner Insulator Kit Side Insulated Foam Panel Air Conditioner Accessories

This window air conditioner insulation set seals the gaps around a window unit. It is made of EVA foam with aluminum foil. The foil reflects sunlight and heat, and the foam adds thermal insulation, dust protection and durability.

The panels help keep cool air in during hot weather and warm air in during winter. They also reduce operating noise, block cold drafts and help prevent energy loss. The foil surface gives the air conditioner unit waterproof protection.

It suits window air conditioners from 5000 to 22000 BTU and works with most standard window units. To install, measure the window space, cut the foam pieces to size and fit them around the unit.

Questions and answers

Will it fit my window AC?
It is sold for units from 5,000 to 22,000 BTU. You measure the window opening and cut the foam to fit, so most standard window units can be sealed.
Does it actually lower my energy bill?
It seals the gaps beside and above the unit, which cuts drafts and air leaks. Savings depend on how leaky your current install is; the foil also reflects sun off the unit area.
Can I use it in winter?
Yes. The foam and foil help keep cold air out around the unit in heating season as well as keeping cool air in during summer.
Does it reduce noise?
It muffles some sound coming through the gaps around the unit. It is thin foam, so do not expect it to quiet a loud compressor.
What is in the box?
One insulation set of foam panels with aluminum foil facing. Adhesive or mounting hardware is not listed, so check before installing.
Can I remove it at the end of the season?
Yes, it is a cut-to-fit panel rather than a permanent fixture. Expect to replace it if it tears or loses shape after removal.
Where is the Universal Window Air Conditioner Insulator Kit Side Insulated Foam Panel Air Conditioner Accessories cheapest?
At Walmart, for $29.56, as of our latest check.
