They may not have reached the evening news, but there have been debates about he best insulation type in a spa, hot tub or swim spa.
There are actually 3 reasons for insulation in your Huston Texas Hot Tub.
1. Maintains Hot Tub temperature - this one is the obvious and best reason for insulation.
Full foam will always out perform any other type of insulation; we use it in coolers, thermos and the walls of our home.
2. Reduces Vibration - engineers will validate the fact that "VIBRATION CAUSES FAILURE". There are nearly three hundred feet of hosing inside the average spa. If the water is passing through these pipes at a high velocity, the hoses will be shaking if FULL FOAM does not stabilize them. Although many will state that a Non-Full Foam spa is easier to fix, it is also guaranteed to fail.
3. Reduces Noise - related to vibration but if you want to reduce NOISE, find a spa with full foam.
The cover will also be a determining factor with your energy bills. A cover that seals to the shell and seals at the seam will provide you with a great lid. The foam inside the cover can range from 2 ¼" to 5" thick, but the density of the foam will offer the most strength. A steel support along the seam will also add strength to the cover to prevent a collapse in the center.
Casual Patio sells Nordic Hot Tubs with standard 2 pound closed cell spray on foam and the OPTIONAL T-20 certified Nordic Wrap insulation.
