Hot Tub Covers and the R-Value

The Myth of R-Value and also conventional foam filled hot tub covers

R-value is a kind of measurement of the capacity to stand up to warmth transfer for materials like the fiberglass insulation in your home or perhaps the protecting foam in hot tub covers The intent is that, the better the R-value, the far better the heat storage and, warm retention would certainly be the primary task of any kind of hot tub cover.

A lot of markets utilizing R-values are controlled by FTC standards. Readily offered insulation needs to pass independent examinations created by American Criteria and also Screening Methods (ASTM) so about be advertised or marked using their R-Value.

The Misled Publics: As there is no FTC identified independent examination for spa covers, So ANY specified R-value specified by a spa cover dealership is in fact an uncontrolled, unmonitored “interpretation” of a provided insulation worth. It is open to misrepresentation as well as abuse, from adding the R-value of an air space in between the water and the bottom of the cover, spacing in between the vinyl and also the cover insulation, or simply coldly inflating the fictitious number. Some hot tub dealers mention solely the known R-value of the insulation itself, however of course that does not imply that it was examined as well as supported to use in hot tub cover applications.

The R-value of the actual foam insulation, regardless of the density, is ONLY ranked for use in COMPLETELY DRY building applications! Which symbolizes that the R ranking of the foam is just applicable should it happen to be used in a wall surface, attic or flooring. Since ought to it were to be used in a damp setting, that kind of insulation would fall short promptly.

Foam Thickness and also Foam Density.

These 2 variables that spa cover suppliers declare impact the R-value of spa covers, when actually that R rating itself has nothing to do with the foam when it is made use of in a hot tub cover. Really, it is as misguiding as the suggestion that a taper on the cover will truly keep it from obtaining hefty.

Real, the foam density and also density would have a bearing on the insulation residential or commercial properties In the event the Use of the foam were in compliance with the designed use an entirely DRY setting.

No matter if the supplier asserts his spa covers are made with one of the most pricey spa cover foam (inflexible cellular polystyrene thermal insulation) available, withstands breakage, vapor absorption as well as chemical damage more than all the others they’ve evaluated. The fact is, R factor is NOT something they check, and also WITHSTANDING breakage and saturation are not the same as PREVENTING it entirely.

When looking for and contrasting spa covers, ALL cases related to R-value of a cover that has foam are completely unsubstantiated. Foam Thickness and Foam Density do not have any type of ADDED R WORTH, because the foam is not created to be applied over a damp setting. The majority of spa cover dealers repeat exactly the same numbers and also subsequently hot tub owners have been educated to believe the lie. Some dealers use some expensive graphs to confirm their claims, nevertheless the main point is those insurance claims can not remain in accordance to the ASTM.

Misconception Busted!

R-value screening of products is finished at room temperature, as well as does not think about dampness as well as vapor. In the spa setting, there is hot water and also great quantities of steamy moisture. Each of which will drastically decrease the R-value of any kind of foam. A spa at 105 degrees will certainly defeat the R-value of any foam evaluated to use in a completely dry application.

Do not enable the R-value of foam be taken into consideration the dimension for spa cover quality. Instead search for a spa cover without any FOAM. Instead, hot tub covers that use air filled chambers as a choice for rigid foam boards will certainly out preform other, in any test or genuine hot tub application. (Hey there, like those from SpaCap.com )

Do not be deceived by claims of high thickness as well as weight, vacuum wrapped in sheets of heat bonded polyethylene, sealed in hefty gauge marine grade vinyl, with chemical resistant scrim as well as sewing. It won’t shield also. It will most definitely still end up being saturated, distorted or busted. It really was outdated thirty years earlier.

SpaCap.com spa covers do not utilize foam panels like the common rigid foam filled hot tub covers. Instead they make use of air chambers to do the insulating. In addition to being extra efficient, the air chambers don’t suck up dampness like every foam-filled cover ever made.
