Hot Tub Covers and the R-Value

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

R-value is a form of dimension of the capability to stand up to heat transfer for materials like the fiberglass insulation in your home or perhaps the protecting foam in hot tub covers The intent is that, the higher the R-value, the much better the heat storage as well as, warmth retention would be the main work of any kind of hot tub cover.

Many sectors utilizing R-values are regulated by FTC requirements. Commercially sold insulation should pass independent examinations developed by American Criteria and Screening Methods (ASTM) so as to be promoted or noted utilizing their R-Value.

The Misled Publics: As there is no FTC acknowledged independent examination for spa covers, So ANY stated R-value mentioned by a spa cover dealer is in fact an unregulated, unmonitored “analysis” of an offered insulation value. It is open to misstatement and 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 plastic and also the cover insulation, or merely coldly pumping up the fictitious number. Some hot tub dealers state solely the recognized R-value of the insulation itself, however naturally that doesn’t indicate that it was checked as well as backed to make use of in hot tub cover applications.

The R-value of the actual foam insulation, regardless of the thickness, is ONLY rated for use in COMPLETELY DRY structure applications! Which signifies the fact that the R ranking of the foam is only suitable should it take place to be applied in a wall, attic or floor. Due to the fact that ought to it were to be used in a wet environment, that kind of insulation would certainly fail rapidly.

Foam Thickness and also Foam Density.

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

Real, the foam thickness as well as thickness would have a bearing on the insulation residential properties In the event the Use of the foam remained in conformity with the made use a totally DRY atmosphere.

Regardless if the supplier claims his spa covers are made with the most expensive spa cover foam (stiff mobile polystyrene thermal insulation) readily available, resists breakage, vapor absorption and also chemical damages greater than all the others they have actually examined. The fact is, R element is NOT something they evaluate, as well as STANDING UP TO breakage and also saturation are not the like PREVENTING it entirely.

When seeking and comparing spa covers, ALL cases related to R-value of a cover that has foam are absolutely dubious. Foam Density and also Foam Thickness do not have any kind of ADDED R VALUE, since the foam is not developed to be used over a wet environment. Most spa cover suppliers repeat exactly the very same numbers as well as subsequently hot tub owners have been educated to think the lie. Some dealerships employ some expensive graphs to corroborate their claims, nonetheless the bottom line is those claims can not remain in conformity to the ASTM.

Misconception Damaged!

R-value testing of products is completed at room temperature, and also doesn’t take into consideration wetness as well as vapor. In the spa atmosphere, there is warm water as well as excellent amounts of steamy wetness. Each which will drastically reduce the R-value of any type of foam. A spa at 105 degrees will defeat the R-value of any foam tested to utilize in a completely dry application.

Do not allow 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 an alternative for rigid foam boards will certainly out preform other, in any kind of examination or genuine hot tub application.

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

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