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 Covers®

  • 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 There are no sections or seams for heat loss like on an outdated conventional hot tub style cover.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.

I am impressed with the workmanship and quality of the new cover. It fits perfectly and is much easier to uncover and recover our pool. You don’t have unsightly stiff covers sticking straight up at each end and there is no gap in the middle that allows trash into your pool. You have one well made cover that can easily be rolled and unrolled by one person. This should be a stock item for all swim spas.

Everything was just as you described. Delivery was very smooth. The crate was easy enough to disassemble. My son and I easily carried the cover to the spa and installation was very simple. The cover is wonderful and has definitely helped in maintaining temperature and chem balance. It is very easy for me to open and close by myself. I have opened it from both in and outside the spa.
