Thermal Information

We all have a general understanding of the insulation R-Rating System.

R-Rating is a measure of how a material resists the flow of heat through that material. There are now many superior, heat-retaining materials available to insulate these days instead of the 50-year-old hot tub style design with thick foam covers.

We at E2E have tested the E2E Swim Spa Cover against the 3 inch R-19 foam cover and the 5 inch R-30 foam cover. The E2E Swim Spa Cover outperformed them both in climate control test chambers, saving customers daily energy consumption and costs.

There are two reasons for this, which link directly to the:

1. Materials used in the E2E Swim Spa Cover

  • We use a full layer of Radiant Barrier to reflect infrared heat waves back into the water which stops radiant heat loss.

2. The design of the E2E Swim Spa Cover.

  • The E2E Cover’s one-piece system locks in heat vapor which stops convective heat loss. There are no sections or seams for heat loss like on an outdated conventional hot tub style cover.
  • Air trapped in our multi-layered cover stops conductive heat loss.

These factors; the locking in of the heat vapor, the air entrapment within the cover and the radiant barrier reflecting heat waves back towards the water is why we outperform the other cover systems.

The E2E Cover provides consumers energy efficiency, one-person ease of use, and longevity.

Wish I had this cover a year ago when we purchased our swim spa. My wife can finally open the spa with ease what a joy! The quality of the outside cover appears to be much greater than that crappy heavy vinyl cover.  Also thanks for supporting us Veterans!

My wife began shopping for cover solutions.  She came across End 2 End amongst her choices.  After reading the reviews and looking at the overall design we decided to go with the End 2 End.  And we are so glad we did!!!  Others have written about the great customer service and assistance and I would only echo those comments as our experience was as good or better.  My wife can now swim anytime she wishes as the cover easily rolls back for her.  I am thrilled by the great seal the cover provides keeping out ALL needles and tree debris!  My filter is so much cleaner and nothing is being sucked into the pumps anymore.  This cover has made the experience of owning a swim spa great! If you have or are contemplating a swim spa, this is the best cover you can have.  Thank you End 2 End!  The entire experience has been terrific and we now thoroughly enjoy having and using our swim spa!!!
