Hot Tub Covers and the R-Value

The Myth of R-Value and standard foam filled Swim Spa Covers

R-value is a kind of dimension of the capability to stand up to warmth transfer for products like the fiberglass insulation in your home or possibly the protecting foam in swim spa covers. The intent is that, the greater the R-value, the better the heat storage space as well as, warmth retention would be the primary task of any kind of Swim Spa Cover

Many markets making use of R-values are regulated by FTC standards. Commercially sold insulation needs to pass independent examinations developed by American Criteria and also Testing Approaches (ASTM) so regarding be advertised or noted using their R-Value.

The Misled Masses: As there is no FTC acknowledged independent test for Swim Spa Covers, So ANY mentioned R-value mentioned by a Swim Spa Cover dealership remains in reality an unregulated, unmonitored “interpretation” of an offered insulation worth. It is open to misstatement as well as abuse, from including the R-value of an air space in between the water and the bottom of the Swim Spa Cover, spacing between the vinyl as well as the Swim Spa Cover insulation, or simply blatantly blowing up the fictitious number. Some spa dealerships mention exclusively the recognized R-value of the insulation itself, yet obviously that does not indicate that it was evaluated and recommended to make use of in Swim Spa Cover applications.

The R-value of the real foam insulation, regardless of the density, is ONLY ranked for usage in DRY structure applications! Which symbolizes the fact that the R score of the foam is just relevant should it occur to be used in a wall, attic room or floor. Due to the fact that ought to it were to be used in a moist atmosphere, that type of insulation would fail quickly.

Foam Thickness and also Foam Density.

These 2 factors that Swim Spa Cover suppliers assert affect the R-value of Swim Spa Covers, when in fact that R rating itself has nothing to do with the foam when it is used in their Swim Spa Covers In fact, it is as deceiving as the suggestion that a taper on the Swim Spa Cover will really keep it from getting hefty.

Real, the foam density and density would certainly have a bearing on the insulation properties In the event the Use of the foam remained in conformity with the developed use a totally DRY setting.

Regardless if the dealer asserts his Swim Spa Covers are made with the most costly Swim Spa Cover foam (rigid cellular polystyrene thermal insulation) offered, stands up to breakage, vapor absorption as well as chemical damages more than all the others they’ve checked. The fact is, R factor is NOT something they evaluate, and also RESISTING damage and also saturation are not the like PREVENTING it entirely.

When seeking and also comparing Swim Spa Covers, ALL claims associated with R-value of Swim Spa Covers that have foam are absolutely dubious. Foam Density as well as Foam Thickness do not have any ADDED R WORTH, since the foam is not made to be used over a wet environment. Many Swim Spa Cover dealerships repeat precisely the very same numbers and as a result swim spa owners have actually been trained to believe the lie. Some suppliers use some elegant graphs to validate their insurance claims, nevertheless the bottom line is those insurance claims can not be in accordance to the ASTM.

Myth Busted!

R-value testing of materials is completed at room temperature, and doesn’t take into consideration moisture as well as vapor. In the spa environment, there is warm water and also excellent amounts of steamy moisture. Each which will considerably reduce the R-value of any type of foam. A spa at 105 degrees will certainly defeat the R-value of any kind of foam checked to use in a dry application.

Do not permit the R-value of foam be thought about the dimension for swim spa cover high quality. Instead search for a Swim Spa Cover without any FOAM. Instead, Swim Spa Covers that use air filled chambers as a choice for rigid foam boards will certainly out preform other, in any test or real Swim Spa Cover application. (Hey there, like those from )

Do not be deceived by claims of high density and also weight, vacuum wrapped in sheets of heat welded polyethylene, sealed in heavy gauge marine quality plastic, with chemical resistant scrim and sewing. It will not shield too. It will definitely still end up being saturated, warped or broken. It truly was out-of-date thirty years back. Swim Spa Covers don’t use foam panels like the regular rigid foam filled Swim Spa Covers Instead they make use of air chambers to do the insulating. Besides being much more effective, the air chambers do not suck up moisture like every foam-filled Swim Spa Cover ever made.
