The Breeze Stop insulation panels feature a 1-inch thick foam core coated with white flexible vinyl, offering both solid insulation and a clean finish. These panels fit window widths up to 36 inches and require cutting down to size with scissors. They cover existing pull-out plastic sides, supplementing rather than replacing them, which improves insulation and keeps out drafts without altering the original AC unit installation.

Designed particularly for U-shaped Midea air conditioners, YYGCL’s foam blocks use high-quality EVA foam to deliver excellent insulation, dust-proof, and noise reduction. The foam helps keep cold or hot air from leaking into your home, maintaining comfort and improving energy efficiency year-round. Its durable construction also promises sustained performance over time.
Memrita Window Air Conditioner Foam Block with Seal Strip
Memrita’s foam blocks come with a seal strip and weather seal tape to ensure a tighter closure between the window frame and AC unit. Made from high-quality foam with excellent heat insulation, these blocks fit U-shaped air conditioners like Midea models well and provide effective blocking against cold air leaks, which leads to reduced drafts and noise penetration.

These insulating foam panels offer a universal design compatible with most window AC units ranging between 5,000 to 22,000 BTU. They effectively seal gaps, blocking dust, pollen, insects, and drafts. The foam’s noise-dampening properties also ensure your space remains quiet and comfortable, while improving overall energy savings by preventing heat transfer through leaks.
Buying Guide For Window Blocks To Seal Air Conditioners
Choosing the right window block for your air conditioner requires consideration of several factors to maximize insulation and efficiency.
Compatibility and Fit
Verify that the foam block or panel matches your air conditioner type and window size. Many products are tailored for U-shaped air conditioners, like Midea models. Universal panels offer broader compatibility but might require trimming for a perfect fit.
Material Quality and Durability
Look for blocks made from high-quality EVA foam or similar materials known for good heat insulation, durability, and softness for easy cutting. Materials should be resistant to dust and moisture to ensure longevity.
Installation Ease
Consider how simple it is to install and cut the foam blocks. Some products come with additional seal strips or weather tape to enhance sealing efficiency. Panels that cover or augment existing plastic sides can be especially user-friendly.
Insulation Performance
Focus on products with proven heat retention and draft blocking capabilities. Good blocks help maintain cool indoor air during summer and retain heat in winter, contributing to lower energy bills.
Noise Reduction
Many foam panels also reduce noise and vibrations associated with running air conditioners. If sound insulation is a priority, select options that highlight noise dampening as a feature.
Aesthetic and Coverage
Some blocks come with a vinyl cover or a finished look in white or black to blend well with window frames and AC units. Check if the product fully covers gaps or only supplements existing side panels.
With these considerations, you can select the best window block that meets your specific air conditioner model requirements and home insulation needs.
