Great Round Pool Insulation

This Thermo-Wall insulation has been a game changer for my round pool. It fits perfectly and has really helped keep the water warm during cooler nights. I noticed a significant drop in heating costs since I installed it, which is always a plus! Plus, it's durable and seems to hold up well against the elements. Highly recommend for anyone wanting to extend their swimming season!

Great insulation

Noticeable difference in heat retention. Glad I invested in this for my above-ground pool.

Effective Pool Insulation

The Thermo-Wall Pool Insulation for 24' Round pools is a great investment. It has noticeably reduced our heating costs by maintaining water temperature more effectively. Installation was straightforward, and the results were immediately noticeable.

Pool wall insulation

The lining was easy to install. It comes with a strip of sticky tape on the top side that helps to hold it on while you are putting it up. You can take it off and on to relocate it. We are glad we decided to add this under our new pool liner. Hoping it does what it says and keeps the pool water warmer. We have a 27’ round 54” wall pool. The walls do feel softer with this product under the liner and we have no wrinkles in the liner either.

Thermo-wall Insulation

I have an old above ground pool I had to do some sidewall repairs to. I decided to invest a little extra while I had it all apart and purchased wall insulation. It arrived quickly, was really easy to install (about an hour with two people), and I am super happy with the heat retention improvement. I live in Ohio and even though we have had lows in the 50s at night already my water temp only drops a few degrees at night. Well worth the money!

Excellent Wall Insulation

After buying regular white wall foam I had issues installing it on the pool wall. After 2 hours of fighting with it and having about a quarter of it done, I got pissed off and went to YouTube to look for a video to see what I was doing wrong and found Thermo-Wall Insulation. When I received it I was in awe. It's kinda like heavy bubble wrap with thick foil. It's more like a padding. I installed it myself on my 18 x 33 above ground pool and it took me about 1.5 hours. It went on nice and smooth, no problems. It has a glue strip on the top which helps the install. It's worth every bit of money spent and I would highly recommend it. However, I never want to replace the liner in my pool ever again because it wasn't easy after 12 years.
