Breeze Stop Surround Insulation Side Panels for Window AC
The Breeze Stop Surround Insulation Side Panels feature 1-inch thick foam covered in durable white vinyl, designed to insulate the sides of your window air conditioner. They fit windows up to 36 inches wide. Though these panels cover the existing plastic side panels of the AC unit, they do not replace them. The foam adds another layer of insulation reducing drafts and improving energy efficiency. The panels need to be cut to the right size with scissors for a perfect fit. Their flexible material works for both winter and summer insulation, helping keep cold air out in the winter and hot air out during summer.

The Garpernics Insulation Foam Block is specifically designed for Midea U-shaped air conditioners as well as Danby models with that profile. Made from high-quality EVA foam, it’s soft and easily cut with a knife to customize to the exact window or unit size. This product fits snugly to prevent air leakage around the window unit, helping maintain indoor temperatures while reducing noise and dust intrusion. Its straightforward installation and tailored fit make it a solid choice for owners of compatible U-shaped window AC models.

By sealing gaps effectively, they block dust, insects, heat, and drafts. The foam also helps reduce AC noise and vibrations, improving overall comfort while promoting energy savings through better insulation.

Buying Guide for Window Blockers for Air Conditioners
Choosing the right window blocker for your AC will depend on several important factors to ensure optimal sealing, insulation, and comfort throughout the year.
Compatibility With Your Air Conditioner
- Unit Shape: Make sure you select a blocker designed for your AC type—U-shaped, rectangular, or other specialized designs.
- Brand Specificity: Some blockers are tailored for brands like Midea or Danby, providing a perfect fit and easier installation.
- Window Size: Verify maximum window width and height supported by the blocker, ensuring it covers gaps effectively.
Material Quality and Insulation
- Foam Density and Thickness: Thicker and denser foam generally offers better insulation against drafts, noise, and dust.
- Vinyl or EVA Coating: Durable outer coatings improve longevity and water resistance, key for outdoor exposure next to windows.
- Environmental Considerations: Look for eco-friendly, dust-proof materials that contribute to indoor air quality.
Installation and Adjustability
- Cut-To-Size Features: Some products require trimming to fit your window precisely; foam softness facilitates this.
- Included Seal Strips and Weather Tape: Extras like sealing tape improve airtightness and prevent leakage at contact points.
- User-Friendly Design: Choose products that don’t require tools or complicated procedures for quick setup and removal.
Energy Efficiency Impact
- Heat and Draft Blocking: The best window blockers reduce cold air infiltration in winter and hot air in summer, helping lower utility bills.
- Noise Reduction: Foam materials can also dampen noise from the outdoor environment as well as vibrations from the unit itself.
Durability and Maintenance
- Weather Resistance: UV resistance and waterproofing extend product life despite seasonal changes.
- Ease of Cleaning: Smooth vinyl or foam surfaces are typically simple to wipe down and maintain.
Considering the above points will help you select the best window blocker tailored to your AC unit’s design and your home’s comfort needs.
