The Myth of R-Value and standard foam filled hot tub covers
R-value is a form of measurement of the capacity to withstand warmth transfer for products like the fiberglass insulation in your house or perhaps the shielding foam in hot tub covers The intent is that, the better the R-value, the better the warm storage space as well as, heat retention would be the main task of any hot tub cover.
A lot of industries making use of R-values are controlled by FTC standards. Commercially marketed insulation needs to pass independent examinations developed by American Standards and also Testing Methods (ASTM) so as to be promoted or noted using their R-Value.
The Misled Publics: As there is no FTC recognized independent examination for spa covers, So ANY stated R-value mentioned by a spa cover supplier is in fact an unregulated, unmonitored “analysis” of an offered insulation value. It is open to misrepresentation and abuse, from including the R-value of an air space in between the water and also all-time low of the cover, spacing between the vinyl as well as the cover insulation, or simply blatantly pumping up the fictitious number. Some hot tub dealers specify specifically the recognized R-value of the insulation itself, but obviously that doesn’t imply that it was checked and backed to make use of in hot tub cover applications.
The R-value of the real foam insulation, regardless of the thickness, is ONLY rated for use in DRY building applications! Which indicates the fact that the R rating of the foam is only suitable needs to it take place to be used in a wall surface, attic or floor. Due to the fact that needs to it were to be made use of in a wet setting, that kind of insulation would certainly fail swiftly.
Foam Density and Foam Density.
These two factors that spa cover dealers assert affect the R-value of spa covers, when actually that R rating itself has nothing to do with the foam when it is made use of in a hot tub cover. Actually, it is as deceiving as the suggestion that a taper on the cover will really maintain it from getting heavy.
Real, the foam density and thickness would have a bearing on the insulation residential or commercial properties In case the Use of the foam remained in conformity with the developed use of a totally DRY setting.
No matter if the dealership asserts his spa covers are made with the most pricey spa cover foam (stiff cellular polystyrene thermal insulation) readily available, withstands damage, vapor absorption as well as chemical damages greater than all the others they have actually tested. The reality is, R aspect is NOT something they check, and STANDING UP TO breakage and saturation are not the same as PREVENTING it completely.
When trying to find and comparing spa covers, ALL cases related to R-value of a cover that has foam are absolutely unverified. Foam Thickness and Foam Thickness do not have any type of ADDED R VALUE, considering that the foam is not created to be applied over a damp setting. Most spa cover dealers repeat exactly the exact same numbers as well as consequently hot tub owners have been trained to think the lie. Some dealers utilize some elegant graphs to confirm their claims, however the main point is those claims can not be in accordance to the ASTM.
R-value screening of materials is completed at room temperature level, and also does not consider dampness as well as vapor. In the spa atmosphere, there is warm water and also excellent quantities of steamy dampness. Each which will drastically reduce the R-value of any kind of foam. A spa at 105 degrees will defeat the R-value of any type of foam tested to make use of in a completely dry application.
Do not permit the R-value of foam be thought about the measurement for spa cover quality. Rather look for a spa cover with NO FOAM. Instead, hot tub covers that use air filled chambers as an alternative for rigid foam boards will certainly out preform other, in any type of examination or actual hot tub application.

Don’t be tricked by claims of high density and weight, vacuum wrapped in sheets of heat welded polyethylene, sealed in heavy gauge marine grade vinyl, with chemical resistant scrim and stitching. It won’t protect also. It will most definitely still come to be saturated, warped or broken. It absolutely was out-of-date thirty years back.
SpaCap.com spa covers do not utilize foam panels like the normal rigid foam filled hot tub covers. Rather they utilize air chambers to do the insulating. Apart from being more efficient, the air chambers do not suck up wetness like every foam-filled cover ever made.
