Gap filler
Would RecommendI bought this to use when caulking a large gap. I works just fine as long as you have adequate space to apply enough caulk.

Worked!
Would RecommendWorked as it was supposed to.
Easy to cut and squeeze into place.
Would RecommendI used this for a gap along my roofline. It allowed me to squeeze it into place and put caulk around it. Supposedly it is closed cell so it should also help seal it up. It is super easy to cut and has good flexibility.
This product was not needed. For our floor installation,
