### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Does what it's supposed to and is holding up well
  

*by C***S on Reviewed in the United States on April 23, 2024*

It was recommended that we stuff lengths of this foam into gaps along the edge of a concrete wall to cut down on mold accumulating from a water control/drainage system.  Seems to be working fine and holding up well.  The lengths of foam rod were coiled and packed in a box and some were kinked from the way it was packed.  It dows seem to seek out its natural shape after time, though.  Good product.

    Used it to insulate space under floor boards
  

*by F***3 on Reviewed in the United States on April 21, 2024*

I used the different sizes to place in the space under the floor boards. I used a putty knife to insert it under the different spaces to stop the draft coming in. Worked perfectly on eliminating drafts under floor boards.
