Hot Tub Covers and the R-Value

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

R-value is a form of dimension of the capability to stand up to heat transfer for products like the fiberglass insulation in your house or maybe the shielding foam in swim spa covers. The intent is that, the better the R-value, the much better the warm storage and, warm retention would be the primary work of any kind of Swim Spa Cover

Many industries utilizing R-values are controlled by FTC requirements. Readily offered insulation must pass independent examinations created by American Standards and Testing Methods (ASTM) so about be promoted or marked using their R-Value.

The Misled Public: As there is no FTC recognized independent test for Swim Spa Covers, So ANY stated R-value stated by a Swim Spa Cover dealer remains in reality an unregulated, unmonitored “interpretation” of a provided insulation worth. It is open to misrepresentation and misuse, from adding the R-value of an air space in between the water as well as all-time low of the Swim Spa Cover, spacing between the vinyl as well as the Swim Spa Cover insulation, or simply coldly pumping up the fictitious number. Some spa suppliers mention solely the known R-value of the insulation itself, yet of course that doesn’t imply that it was checked and also supported to use in Swim Spa Cover applications.

The R-value of the real foam insulation, despite the density, is ONLY ranked for usage in COMPLETELY DRY structure applications! Which represents that the R score of the foam is just appropriate should it take place to be used in a wall surface, attic room or floor. Due to the fact that should it were to be used in a moist environment, that sort of insulation would fall short rapidly.

Foam Thickness and Foam Density.

These 2 aspects that Swim Spa Cover dealers assert impact the R-value of Swim Spa Covers, when in fact that R score itself has nothing to do with the foam when it is made use of in their Swim Spa Covers Actually, it is as misleading as the idea that a taper on the Swim Spa Cover will really maintain it from getting hefty.

Real, the foam density and also density would have a bearing on the insulation residential properties In the event the Use of the foam remained in conformity with the designed use a completely DRY atmosphere.

No matter if the dealer claims his Swim Spa Covers are made with one of the most pricey Swim Spa Cover foam (rigid cellular polystyrene thermal insulation) offered, stands up to damage, vapor absorption and chemical damage more than all the others they have actually evaluated. The fact is, R variable is NOT something they evaluate, and also WITHSTANDING damage as well as saturation are not the like AVOIDING it entirely.

When trying to find and comparing Swim Spa Covers, ALL claims related to R-value of Swim Spa Covers that have foam are entirely unsubstantiated. Foam Density and also Foam Thickness do not have any ADDED R WORTH, given that the foam is not designed to be applied over a damp atmosphere. The majority of Swim Spa Cover dealerships repeat precisely the exact same numbers and consequently swim spa owners have actually been trained to think the lie. Some suppliers utilize some expensive graphs to substantiate their claims, nevertheless the bottom line is those claims could not be in accordance to the ASTM.

Myth Busted!

R-value screening of products is finished at room temperature level, as well as does not take into consideration moisture and also vapor. In the spa atmosphere, there is warm water and great amounts of steamy moisture. Each of which will drastically lower the R-value of any type of foam. A spa at 105 levels will certainly defeat the R-value of any type of foam evaluated to utilize in a dry application.

Do not allow the R-value of foam be taken into consideration the measurement for swim spa cover high quality. Instead look for a Swim Spa Cover without FOAM. Instead, Swim Spa Covers that use air filled chambers as an alternative for rigid foam boards will out preform other, in any test or actual Swim Spa Cover application.
