Hot Tub Covers and the R-Value

The Misconception of R-Value as well as standard foam filled hot tub covers

R-value is a type of dimension of the ability to resist warmth transfer for products like the fiberglass insulation in your residence or possibly the insulating foam in hot tub covers The intent is that, the greater the R-value, the better the warmth storage space and also, warm retention would certainly be the main job of any kind of hot tub cover.

The majority of markets using R-values are managed by FTC requirements. Readily offered insulation has to pass independent examinations created by American Criteria as well as Testing Approaches (ASTM) so regarding be marketed or marked utilizing their R-Value.

The Misled Masses: As there is no FTC recognized independent examination for spa covers, So ANY specified R-value mentioned by a spa cover supplier remains in truth an unregulated, unmonitored “analysis” of a provided insulation value. It is open to misstatement and also misuse, from adding the R-value of an air space in between the water and also the bottom of the cover, spacing in between the vinyl as well as the cover insulation, or just coldly pumping up the fictitious number. Some hot tub dealers mention specifically the known R-value of the insulation itself, yet obviously that doesn’t suggest that it was tested as well as supported to make use of in hot tub cover applications.

The R-value of the real foam insulation, no matter the thickness, is ONLY ranked for use in DRY building applications! Which indicates the fact that the R rating of the foam is just applicable ought to it happen to be used in a wall, attic or floor. Due to the fact that ought to it were to be made use of in a damp environment, that type of insulation would certainly stop working quickly.

Foam Density and Foam Density.

These 2 variables that spa cover dealerships claim influence the R-value of spa covers, when actually that R score 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 idea that a taper on the cover will truly maintain it from obtaining hefty.

Real, the foam density and also density would have a bearing on the insulation residential properties In case the Use of the foam remained in conformity with the developed use of an entirely DRY atmosphere.

No matter if the dealer claims his spa covers are made with the most pricey spa cover foam (stiff cellular polystyrene thermal insulation) offered, stands up to damage, vapor absorption and also chemical damages more than all the others they have actually tested. The reality is, R aspect is NOT something they evaluate, and RESISTING damage and also saturation are not the like PREVENTING it altogether.

When seeking and also comparing spa covers, ALL claims associated with R-value of a cover that has foam are totally dubious. Foam Density and also Foam Density do not have any ADDED R WORTH, since the foam is not developed to be applied over a wet setting. A lot of spa cover dealerships repeat exactly the very same numbers and also as a result hot tub owners have been educated to think the lie. Some dealerships use some expensive graphs to validate their insurance claims, however the bottom line is those insurance claims could not be in conformity to the ASTM.

Myth Broken!

R-value testing of materials is completed at room temperature level, as well as doesn’t consider moisture and also vapor. In the spa setting, there is hot water as well as great quantities of steamy moisture. Each which will significantly decrease the R-value of any type of foam. A spa at 105 degrees will beat the R-value of any type of foam checked to use in a completely dry application.

Don’t enable the R-value of foam be taken into consideration the measurement for spa cover quality. Instead look for a spa cover without FOAM. Instead, hot tub covers that use air filled chambers as an alternative for rigid foam boards will certainly out preform any other, in any kind of examination or real hot tub application. (Hi, like those from SpaCap.com )

Don’t be fooled by claims of high density and weight, vacuum wrapped in sheets of heat welded polyethylene, sealed in hefty gauge marine grade plastic, with chemical resistant scrim and also sewing. It won’t protect as well. It will definitely still become saturated, deformed or broken. It genuinely was outdated thirty years earlier.

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