Hot Tub Covers and the R-Value

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

R-value is a type of dimension of the capability to withstand warm transfer for products like the fiberglass insulation in your residence or maybe the insulating foam in hot tub covers The intent is that, the higher the R-value, the much better the warmth storage and also, warmth retention would certainly be the primary job of any type of hot tub cover.

A lot of industries using R-values are managed by FTC standards. Commercially sold insulation has to pass independent tests created by American Criteria and also Screening Methods (ASTM) so regarding be advertised or noted utilizing their R-Value.

The Misled Publics: As there is no FTC identified independent test for spa covers, So ANY mentioned R-value mentioned by a spa cover dealer remains in fact an unregulated, unmonitored “interpretation” of a given insulation value. It is open to misstatement as well as abuse, from including the R-value of an air space between the water and also the bottom of the cover, spacing between the plastic and the cover insulation, or just coldly inflating the make believe number. Some hot tub dealers mention solely the well-known R-value of the insulation itself, yet of course that does not imply that it was checked as well as recommended to use in hot tub cover applications.

The R-value of the actual foam insulation, no matter the density, is ONLY rated for use in DRY building applications! Which represents that the R rating of the foam is just applicable should it take place to be used in a wall, attic or floor. Since should it were to be used in a damp environment, that kind of insulation would fall short quickly.

Foam Thickness as well as Foam Density.

These two factors that spa cover suppliers declare impact the R-value of spa covers, when as a matter of fact that R ranking itself has nothing to do with the foam when it is utilized in a hot tub cover. In fact, it is as deceiving as the suggestion that a taper on the cover will actually keep it from obtaining hefty.

Real, the foam density as well as density would have a bearing on the insulation residential properties In the event the Use of the foam remained in compliance with the made use of an entirely DRY environment.

No matter if the dealership claims his spa covers are made with the most pricey spa cover foam (inflexible mobile polystyrene thermal insulation) available, resists damage, vapor absorption as well as chemical damage greater than all the others they’ve evaluated. The fact is, R variable is NOT something they evaluate, and also STANDING UP TO damage as well as saturation are not the same as PREVENTING it altogether.

When looking for and contrasting spa covers, ALL cases associated with R-value of a cover that has foam are totally unverified. Foam Thickness and Foam Thickness do not have any type of ADDED R VALUE, since the foam is not created to be applied over a wet setting. Many spa cover dealerships repeat exactly the same numbers as well as consequently hot tub owners have been trained to think the lie. Some dealerships use some expensive graphs to confirm their claims, however the bottom line is those cases could not remain in conformity to the ASTM.

Myth Busted!

R-value testing of materials is finished at room temperature level, as well as doesn’t think about wetness and also vapor. In the spa environment, there is warm water and also great quantities of steamy moisture. Each which will substantially minimize the R-value of any foam. A spa at 105 degrees will beat the R-value of any type of foam examined to make use of in a dry application.

Don’t permit the R-value of foam be considered the dimension for spa cover high quality. Rather 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 out preform other, in any examination or genuine hot tub application.

Don’t be fooled by claims of high density and also 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 will not insulate also. It will definitely still end up being saturated, deformed or broken. It genuinely was obsolete thirty years back.

SpaCap.com spa covers do not use foam panels like the normal rigid foam filled hot tub covers. Instead they use air chambers to do the insulating. Besides being more efficient, the air chambers don’t suck up moisture like every foam-filled cover ever made.
