Seal windows and doors like a pro with NO WARP™ Foam — specially designed for areas where frame stability matters. Unlike regular polyurethane, it expands gently using self-venting technology that prevents pressure damage. The result: a durable, airtight seal that boosts energy efficiency, reduces heat loss, and helps prevent moisture problems. With a bright white finish and Class 1 fire rating, NO WARP™ is ideal for both indoor and outdoor use.

(This review was collected as part of a promotion.) This product is easy to use and works well. It is a foam so I used to fill a very deep, long rotted out section of a window Does a good job, While it can be used as an all-purpose foam, This revolutionary expanding polyurethane foam is designed to air seal without exerting pressure that can be detrimental to window or door frame stability.
It is the perfect size for use at a cheap price.
The result was excellent when I used for the room window.

Easy to use 👍🏻

(This review was collected as part of a promotion.) This worked very well to seal up our doors and windows before finishing up with borders. We noticed a significant difference in draft, and plan to do the other windows. I feel the quality is top tier and will last a long time.

Very good

(This review was collected as part of a promotion.) I was actually highly impressed with this product.  I didn't have super high hopes because I hadn't heard of the Brannon but doing some exterior gap filling around basement window frames where previous filling had disintegrated was super easy. It expanded and filled the gaps in seconds. There was no mess or issues at all. I used so much and the can still feel pretty full of product. I have some other jobs I want to use this product for once it warms up.

Easy to use and no mess!

(This review was collected as part of a promotion.) We purchased our home over 5 years ago and have slowly started some small renovations. This @dapcanada No Warp window and door foam came in handy to seal up our door frame in our basement. It's very simply to use and comes with the nozzle to spray exactly where you want it to go. It does expand slightly but it can be trimmed to make it flush with the frame if you over spray. It dries pretty quickly and claims to be tack free in about 10 mins. I am not sure if it was the temperature around the frame but it took a little longer than 10 mins for this to live up to that claim. We used it in an interior door but this foam is versatile and can be used indoors or outdoors. Overall, I'm impressed with this product and love the range of products that Dap has available at our local hardware store. As always, safety first! Goggles and gloves are recommended!

Great affordable option for basic home renovations

(This review was collected as part of a promotion.) This product is great. It has helped me saved money on heating my house because it works so good at keeping the cold air out by providing a great seal. It is super easy to use. I love that it comes with an extra straw. It doesn't have a strong odour which I love and the packaging is super nice and sleek. If you ever need a quick seal for a door or a window, I would definitely recommend this.

If you want to save money on heating, get this pro

(This review was collected as part of a promotion.) This product is super easy to use and perfect for sealing around door frames and windows to ensure no air or bugs get into the house from the outside. The pressure from the can is low so it's easy to control where you apply the product which makes it's easier to use.

Easy to use and effective

(This review was collected as part of a promotion.) The DAP Foam NoWarp® Window & Door Sealant is hands down the best sealant I've ever used. It expands perfectly to fill gaps without putting pressure on the window or door frames, so there's no risk of warping. The low-pressure formula makes it incredibly easy to apply, and it creates a tight air seal that completely stops drafts—my home already feels so much more energy-efficient. I also love that it's fire retardant and creates a moisture barrier for added protection. The bright white finish blends in seamlessly, and the performance is unmatched. Highly recommend for anyone tackling home improvement projects!

Great product

(This review was collected as part of a promotion.) So I recently redid the trim around a couple of old windows in my house, and I used DAP's No Warp Window and Door Sealant for the job. I actually received the product for free in exchange for my honest review—and after using it, I'm glad I got the chance to test it out.

Application:
The application was super straightforward. The sealant has a nice, thick consistency that makes it easy to control—especially on vertical surfaces around doors and windows. It didn't drip or sag, which made the whole process a lot cleaner and less frustrating than some other caulks I've worked with.

Work Time and Cleanup:
I had about 20 minutes of work time before it started setting up, which was plenty to smooth it out and make adjustments. Cleanup was easy with a damp rag while it was still wet, and once it cured, it was rock solid.

Performance:
This is where it really impressed me. After a couple months of wild temperature swings and a few heavy rains, the sealant hasn't cracked, shrunk, or pulled away from the trim. True to its name, there's been no warping at all. It stays flexible, which is exactly what I was hoping for.

Paintability:
No issues there—paint adhered well and blended in with the surrounding trim. No weird shine or texture difference.

Final Thoughts:
Even though I received the product for free to test, this is 100% something I would buy again. It performed better than a lot of other sealants I've tried in the past, and it really seems like it'll hold up long-term. If you're looking for something reliable around windows and doors, this stuff is solid.

DAP No Warp Window and Door Sealant applied easily

(This review was collected as part of a promotion.) If you have cracks, holes, or just need to replace the old seal, you need to try this foam.  It's super easy to use.  You don't even have to worry about excess foam because you can easily cut it off.  You don't need to spray a lot because the foam grows to fill the gap.  It comes with a replacement tube/straw. Very affordable!

So easy to use!

(This review was collected as part of a promotion.) If you're looking for a reliable, no-fuss sealant, **DAP No Warp Sealant in White** is a solid choice! It applies smoothly, dries evenly, and—true to its name—won't warp or shrink over time. The white finish blends well for a clean look, and it's super easy to work with, whether you're sealing doors, windows, or trim. Plus, it holds up really well, so no worries about cracking or peeling. Definitely a go-to for a strong, lasting seal!

Just be careful to touch your hands with it

(This review was collected as part of a promotion.) I didn't really notice any benefit to using this product. Maybe the weather was too cold. am willing to try it again, once the weather warms up. I will update my review if I find it more effective my next use.

Wasn't as I had hoped

DAP No Warp Window & Door Sealant 340g spray can with blue label and white text, low pressure foam for sealing window and door frames and jambs without warping, weatherproof with reusable bonus straw for precise application.
