From the Manufacturer GREAT STUFF Gaps & Cracks is a polyurethane-based insulating foam sealant that fills, air-seals and insulates small gaps (up to 1 inch) inside or out. But you probably guessed as much from the name. What you might not have guessed is how easy it is to use (thanks to the straw applicator) or how it expands to take the shape of cracks and voids to form a durable, airtight, and water-resistant bond that eliminates unwanted airflow and helps reduce condensation. ## Features - Elegant design and Smooth finish - Expanding foam sealant for insulation and air sealing - 20-ounce can for easy application in various areas - Ivory, blends well with most surfaces - Great for both interior and exterior use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002YX98O | | Best Sellers Rank | #4,605 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #9 in Industrial Joint Sealants | | Brand Name | Great Stuff | | Color | Ivory | | Compatible Material | Polyurethane | | Customer Reviews | 4.5 4.5 out of 5 stars (1,896) | | Global Trade Identification Number | 00074985001567 | | Included Components | Expanding foam sealant | | Item Dimensions | 2.75 x 2.75 x 9.5 inches | | Item Form | Foam | | Item Type Name | Insulating Foam Sealant | | Item Weight | 20 Ounces | | Manufacturer | Great Stuff | | Material Type | Polyurethane | | Model | 157911 | | Number of Items | 1 | | Part Number | 157911 | | Style Name | Gaps & Cracks | | Supported Standards | ASTM C-920 | | Surface Recommendation | Wood | | UPC | 074985001567 | | Unit Count | 20.0 Ounce | | Warranty Description | Warranty | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Great Stuff - **Item Weight:** 20 Ounces - **Item dimensions L x W x H:** 2.75 x 2.75 x 9.5 inches - **Material:** Polyurethane - **Style:** Gaps & Cracks ## Images ![157911 Insulating Foam Sealant, 20 Ounce, Ivory - Image 1](https://m.media-amazon.com/images/I/711Ut2xjZ+L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the R-rating on this?** A: Hi Dave! The initial R-value is 4.3 per inch and the aged R-value is 3.7. Good luck with your project! **Q: Is closed or open cell foam?** A: Hi Meggi, This is a closed cell foam. **Q: can this be used to fill holes between dry wall and hardwood, then covered with molding? Will the foam crack if a nail goes into it?** A: This is the perfect place to use this foam! I did this in my own home recently when we were installing new baseboard. You can apply the foam in the gap, and like others said be careful about overfilling because it does expand quite a lot. I also highly recommend buying our Cleaner / Amazon # B0002YWRG4 because you can spray this on a paper towel and clean up foam when it's still wet. It's a useful product for any project using GREAT STUFF foams. Don't worry if it puffs out too much, you can cut, sand, caulk or paint this foam once fully cured/dry. The foam will not crack if you nail through it but it also is not structural so you'll need to make sure you're nailing the molding into the wall. Good luck with your project! **Q: is it safe around a hot baseboard heater pipe coming into the room through the floor?? thats where mice get into the rooms from under the floor** A: I looked at the can and it doesn't really say. The stuff before it cures is full of flammable gas but it doesn't say anything about keeping the cured material from heat. Now, that being said, (I'm putting on my professional chemist hat) Great Stuff is a polyurethane. And polyurethanes are flammable. So, I would be concerned if the area got very hot, say over 150F.
