Buying them on desertcart is it cheaper option as compared to the hardware store. Arrived promptly, no complaints. Review: It's foam.. it works.. - What can I say?? It's foam. Lol seriously tho, it doesn't seem like it's good quality, it's hard to describe in writing except to say it looks & feels "dense", not cheaply made like the kind that sort of falls apart when you handle it. I used it to fill a rather large gap where my attic door meets the frame. I was using self adhesive weather stripping around the edges but where it is not far from a heat vent they just keep falling off. I wedged this foam in there and it stays put. ## Features - Resistant To Sunlight, Moisture And Extreme Temperatures - Reduces Outside Noise And Vibrations - Brand Name: Frost King ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000LNKGGE | | Best Sellers Rank | #19,884 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #45 in Accessories (Home & Kitchen) | | Brand | Frost King | | Brand Name | Frost King | | Color | White | | Customer Reviews | 4.4 out of 5 stars 1,956 Reviews | | Global Trade Identification Number | 00077578051680 | | Included Components | Hardware; Weatherstripping;weather-stripping | | Item Dimensions L x W | 40"L x 1.5"W | | Item Thickness | 1.5 Inches | | Item Type Name | AC FOAM WEATHER SEAL | | Item Weight | 14.15 g | | Manufacturer | Frost King | | Manufacturer Part Number | AC41WA | | Material | Foam | | Material Type | Foam | | Model Number | AC41WA | | Number of Items | 1 | | Product Dimensions | 40"L x 1.5"W | | Recommended Uses For Product | sealing gaps around window air conditioners to enhance their performance and energy efficiency, reducing outside noise and vibrations for a more comfortable indoor environment Recommended Uses For Product sealing gaps around window air conditioners to enhance their performance and energy efficiency, reducing outside noise and vibrations for a more comfortable indoor environment See more | | UPC | 077578051680 | | Unit Count | 3.33 Feet | ## Product Details - **Brand:** Frost King - **Color:** White - **Item Thickness:** 1.5 Inches - **Material:** Foam - **Product Dimensions:** 40"L x 1.5"W ## Images ![AC41WA AC Foam Weather Seal, Heavy Duty 1-1/2" W, 1/2" T, 40" L, White - Image 1](https://m.media-amazon.com/images/I/61dTvvkCrZL.jpg) ![AC41WA AC Foam Weather Seal, Heavy Duty 1-1/2" W, 1/2" T, 40" L, White - Image 2](https://m.media-amazon.com/images/I/71jg6aEJouL.jpg) ![AC41WA AC Foam Weather Seal, Heavy Duty 1-1/2" W, 1/2" T, 40" L, White - Image 3](https://m.media-amazon.com/images/I/71Z+74bVdbL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is this for filling gaps on the outside or in the room, inside?** A: You install it in the air gaps on the inside of the room. **Q: Does this foam have an adhesive on it?** A: no adhesive ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as expected *by A***E on November 30, 2025* This work as expected and don't deteriorate over time.
