Hot Tub Covers and the R-Value

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

R-value is a kind of measurement of the capacity to stand up to warm transfer for products like the fiberglass insulation in your house or maybe the shielding foam in hot tub covers The intent is that, the higher the R-value, the much better the heat storage and also, warm retention would be the main job of any hot tub cover.

A lot of sectors making use of R-values are managed by FTC requirements. Readily offered insulation needs to pass independent tests created by American Requirements and also Testing Approaches (ASTM) so as to be advertised or noted utilizing their R-Value.

The Misled Masses: As there is no FTC identified independent examination for spa covers, So ANY stated R-value specified by a spa cover dealership remains in reality an unregulated, unmonitored “interpretation” of a given insulation value. It is open to misstatement and abuse, from adding the R-value of an air space in between the water as well as the bottom of the cover, spacing between the vinyl as well as the cover insulation, or merely coldly inflating the make believe number. Some hot tub suppliers state exclusively the recognized R-value of the insulation itself, however obviously that doesn’t indicate that it was evaluated and also recommended to make use of in hot tub cover applications.

The R-value of the actual foam insulation, despite the density, is ONLY ranked for use in DRY structure applications! Which represents that the R score of the foam is only relevant needs to it take place to be applied in a wall surface, attic room or flooring. Due to the fact that needs to it were to be utilized in a damp atmosphere, that sort of insulation would certainly fall short rapidly.

Foam Thickness as well as Foam Thickness.

These two variables that spa cover suppliers declare impact the R-value of spa covers, when in fact that R rating itself has nothing to do with the foam when it is used in a hot tub cover. Actually, it is as misguiding as the concept that a taper on the cover will really keep it from obtaining hefty.

Real, the foam density as well as density would have a bearing on the insulation residential or commercial properties In the event the Use of the foam remained in compliance with the made use a completely DRY atmosphere.

Regardless if the dealership declares his spa covers are made with the most pricey spa cover foam (stiff cellular polystyrene thermal insulation) readily available, withstands damage, vapor absorption and also chemical damage more than all the others they’ve evaluated. The truth is, R variable is NOT something they check, and also WITHSTANDING damage and saturation are not the like AVOIDING it completely.

When trying to find and comparing spa covers, ALL insurance claims related to R-value of a cover that has foam are totally dubious. Foam Density as well as Foam Density do not have any ADDED R WORTH, since the foam is not developed to be used over a wet atmosphere. Many spa cover dealerships repeat exactly the very same numbers and also as a result hot tub proprietors have been trained to think the lie. Some suppliers utilize some expensive graphs to confirm their cases, nonetheless the main point is those claims can not remain in conformity to the ASTM.

Misconception Busted!

R-value testing of materials is finished at room temperature level, and also doesn’t think about dampness as well as vapor. In the spa atmosphere, there is warm water and also good quantities of steamy moisture. Each which will considerably reduce the R-value of any kind of 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 taken into consideration the measurement for spa cover quality. Rather look for a spa cover without FOAM. Instead, hot tub covers that use air filled chambers as a choice for rigid foam boards will out preform other, in any kind of test or genuine hot tub application. (Hello, like those from SpaCap.com )

Do not be deceived by claims of high thickness and weight, vacuum wrapped in sheets of heat welded polyethylene, sealed in heavy gauge marine grade plastic, with chemical resistant scrim and stitching. It will not insulate also. It will definitely still become saturated, deformed or damaged. It genuinely was outdated thirty years earlier.

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