Hot Tub Covers and the R-Value

The Myth of R-Value as well as conventional foam filled hot tub covers

R-value is a type of measurement of the ability to stand up to warmth transfer for products like the fiberglass insulation in your house or possibly the shielding foam in hot tub covers The intent is that, the better the R-value, the much better the heat storage space as well as, warmth retention would be the primary work of any hot tub cover.

Most sectors utilizing R-values are controlled by FTC criteria. Commercially sold insulation needs to pass independent examinations created by American Standards as well as Testing Methods (ASTM) so as to be advertised or marked utilizing their R-Value.

The Misled Masses: As there is no FTC recognized independent examination for spa covers, So ANY stated R-value mentioned by a spa cover dealership is in truth an unregulated, unmonitored “analysis” of a given insulation value. It is open to misstatement and abuse, from including the R-value of an air space between the water as well as the bottom of the cover, spacing between the vinyl as well as the cover insulation, or merely coldly pumping up the fictitious number. Some hot tub dealerships specify specifically the well-known R-value of the insulation itself, however obviously that does not mean that it was checked and recommended to make use of in hot tub cover applications.

The R-value of the real foam insulation, despite the density, is ONLY ranked for use in DRY building applications! Which signifies the fact that the R score of the foam is just suitable ought to it take place to be applied in a wall surface, attic room or floor. Due to the fact that ought to it were to be used in a moist atmosphere, that type of insulation would fall short rapidly.

Foam Density and Foam Density.

These 2 factors that spa cover suppliers assert influence the R-value of spa covers, when in fact that R score itself has nothing to do with the foam when it is made use of in a hot tub cover. Actually, it is as misleading as the idea that a taper on the cover will truly maintain it from obtaining heavy.

True, the foam thickness and also density would have a bearing on the insulation residential or commercial properties In the event the Use of the foam were in conformity with the designed use of a completely DRY environment.

No matter if the dealership declares his spa covers are made with the most expensive spa cover foam (inflexible cellular polystyrene thermal insulation) readily available, resists breakage, vapor absorption as well as chemical damages more than all the others they have actually evaluated. The reality is, R element is NOT something they examine, and STANDING UP TO breakage and saturation are not the same as PREVENTING it entirely.

When searching for as well as comparing spa covers, ALL insurance claims connected with R-value of a cover that has foam are completely dubious. Foam Thickness as well as Foam Density do not have any kind of ADDED R VALUE, given that the foam is not designed to be used over a damp environment. Most spa cover dealers repeat precisely the exact same numbers and also subsequently hot tub proprietors have actually been trained to believe the lie. Some suppliers utilize some elegant charts to substantiate their cases, nonetheless the main point is those insurance claims can not remain in conformity to the ASTM.

Misconception Broken!

R-value screening of products is finished at room temperature level, as well as does not consider wetness as well as vapor. In the spa setting, there is hot water as well as good quantities of steamy dampness. Each of which will dramatically decrease the R-value of any foam. A spa at 105 degrees will beat the R-value of any type of foam checked to make use of in a dry application.

Do not allow the R-value of foam be considered the dimension for spa cover quality. Instead look for a spa cover without any FOAM. Instead, hot tub covers that use air filled chambers as an option for rigid foam boards will out preform other, in any kind of test or actual hot tub application. (Hello, like those from SpaCap.com )

Don’t be mislead by claims of high density as well as weight, vacuum wrapped in sheets of heat welded polyethylene, secured in heavy gauge marine grade vinyl, with chemical resistant scrim and also sewing. It won’t insulate as well. It will absolutely still end up being saturated, deformed or busted. It genuinely was out-of-date thirty years earlier.

SpaCap.com spa covers don’t make use of foam panels like the regular rigid foam filled hot tub covers. Rather they make use of air chambers to do the insulating. Besides being extra reliable, the air chambers don’t suck up dampness like every foam-filled cover ever made.
