Customer Reviews for Frost King 5/8 in. x 20 ft. Polyurethane Caulk Saver

We added new windows to every room in our home. All we have done from the outside so far is add this rope insulation. It has worked wondefully!! The rooms feel great! We are going to be adding regular caulk and trim but, for now, this has been wonderful!

Useful stuff for filling cracks.

Did exactly what I needed it to do. Used to fill gaps in between newer vinyl siding and original window before caulking and painting.

Doesn't work as advertised

Works great to fill large gaps and not waste caulk

Used this in conjunction with frost king 5/16"X1/4"X17' D EPDM W/S TAPE-W. To prevent a water breach emanating from a storm door. Works great.

Seems to work as expected so far.

I purchased these to slip in the tracks on my new hurricane shutters to keep the tracks clean from debris.

Used to fill gap between Pergo floor and baseboard. Worked Good. Performed as expected after caulked.

Resolved my problem.Thanks, Frost King.

I hope u have it 1:50 inch that will be Easier

Easy to use expansion strip filler

Used around inside of a sky light...without adding caulk over it. Did exactly what I needed as an air & moisture seal!

Good product came as described

I used this product to fill up various cracks in my home.

does what its supposed to!

Open cell Poly caulk saver, worked for what it was needed for, fast shipping and cheaper than competitors.

Using this as a caulk backer in the seams of my large concrete driveway is a great way of filling the cracks and saving on caulk, but still having the ability to expand and contract with the weather. I actually had to purchase the 3/8 and 3/4 size also because of the varying widths of the cracks. They all worked great! And, I got it done before the snow started flying.

Filled the gaps as expected.

I used this as backing insulation. Very easy to install and works great A very cheap
