Hot Tub Covers and the R-Value

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

R-value is a type of measurement of the ability to resist warm transfer for materials like the fiberglass insulation in your home or possibly the insulating foam in hot tub covers The intent is that, the better the R-value, the much better the heat storage space and also, warmth retention would be the key job of any kind of hot tub cover.

A lot of markets utilizing R-values are regulated by FTC standards. Readily marketed insulation has to pass independent tests developed by American Criteria and Testing Methods (ASTM) so regarding be marketed or noted utilizing their R-Value.

The Misled Masses: As there is no FTC recognized independent examination for spa covers, So ANY mentioned R-value specified by a spa cover dealer is in reality an unregulated, unmonitored “analysis” of a given insulation worth. It is open to misrepresentation and abuse, from adding the R-value of an air space between the water as well as the bottom of the cover, spacing in between the vinyl and the cover insulation, or just blatantly blowing up the fictitious number. Some hot tub dealers specify solely the recognized R-value of the insulation itself, yet obviously that doesn’t suggest that it was checked and also backed to make use of in hot tub cover applications.

The R-value of the actual foam insulation, despite the thickness, is ONLY rated for use in COMPLETELY DRY building applications! Which indicates that the R rating of the foam is just relevant should it take place to be applied in a wall surface, attic room or floor. Since must it were to be used in a wet atmosphere, that type of insulation would certainly fail swiftly.

Foam Thickness and also Foam Thickness.

These 2 variables that spa cover suppliers claim influence 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 used in a hot tub cover. Really, it is as misinforming as the concept that a taper on the cover will actually maintain it from getting heavy.

Real, the foam thickness and also thickness would certainly have a bearing on the insulation properties In the event the Usage of the foam remained in compliance with the made use a completely DRY setting.

No matter if the supplier asserts his spa covers are made with the most costly spa cover foam (stiff cellular polystyrene thermal insulation) offered, withstands breakage, vapor absorption as well as chemical damages more than all the others they’ve checked. The fact is, R factor is NOT something they test, as well as WITHSTANDING damage and also saturation are not the like PREVENTING it altogether.

When seeking as well as contrasting spa covers, ALL insurance claims related to R-value of a cover that has foam are totally unsubstantiated. Foam Thickness and Foam Density do not have any ADDED R WORTH, since the foam is not made to be used over a damp environment. Most spa cover suppliers repeat specifically the very same numbers and also as a result hot tub owners have been trained to believe the lie. Some suppliers employ some elegant charts to corroborate their insurance claims, however the bottom line is those insurance claims could not be in accordance to the ASTM.

Misconception Busted!

R-value screening of materials is completed at room temperature, and also does not take into account wetness and also vapor. In the spa atmosphere, there is hot water and also great amounts of steamy wetness. Each of which will significantly minimize the R-value of any kind of foam. A spa at 105 degrees will defeat the R-value of any foam examined to use in a dry application.

Don’t permit the R-value of foam be taken into consideration the measurement for spa cover high quality. Instead search for a spa cover without FOAM. Instead, hot tub covers that use air filled chambers as an alternative for rigid foam boards will out preform any other, in any kind of test or genuine hot tub application. (Hi, 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 plastic, with chemical resistant scrim and also sewing. It won’t shield also. It will definitely still end up being saturated, deformed or busted. It genuinely was out-of-date thirty years back.

SpaCap.com spa covers do not make use of foam panels like the normal rigid foam filled hot tub covers. Instead they make use of air chambers to do the insulating. Other than being much more efficient, the air chambers do not suck up moisture like every foam-filled cover ever made.
