The Misconception of R-Value as well as standard foam filled hot tub covers
R-value is a kind of measurement of the capability to resist warm transfer for products like the fiberglass insulation in your residence or maybe the protecting foam in hot tub covers The intent is that, the better the R-value, the far better the heat storage space and, heat retention would be the key work of any type of hot tub cover.
Most sectors utilizing R-values are managed by FTC criteria. Readily offered insulation must pass independent examinations developed by American Standards and also Screening Techniques (ASTM) so about be advertised or noted using their R-Value.
The Misled Publics: As there is no FTC identified independent test for spa covers, So ANY mentioned R-value stated by a spa cover supplier remains in fact an uncontrolled, unmonitored “interpretation” of a provided insulation worth. It is open to misrepresentation as well as misuse, from including the R-value of an air space between the water and also all-time low of the cover, spacing between the plastic and the cover insulation, or just coldly inflating the make believe number. Some hot tub suppliers state exclusively the well-known R-value of the insulation itself, however certainly that doesn’t suggest that it was evaluated and endorsed to use in hot tub cover applications.
The R-value of the real foam insulation, no matter the thickness, is ONLY rated for usage in COMPLETELY DRY structure applications! Which indicates the fact that the R ranking of the foam is just applicable needs to it take place to be used in a wall, attic or floor. Since must it were to be utilized in a moist environment, that sort of insulation would fall short promptly.
Foam Thickness and also Foam Density.
These 2 elements that spa cover suppliers claim impact the R-value of spa covers, when as a matter of fact that R rating itself has nothing to do with the foam when it is made use of in a hot tub cover. Really, it is as misinforming as the suggestion that a taper on the cover will really keep it from obtaining heavy.
True, the foam thickness and also density would certainly have a bearing on the insulation buildings In case the Use of the foam were in compliance with the made use an entirely DRY setting.
No matter if the dealership declares his spa covers are made with the most costly spa cover foam (inflexible cellular polystyrene thermal insulation) available, stands up to damage, vapor absorption as well as chemical damages greater than all the others they’ve checked. The truth is, R factor is NOT something they examine, and STANDING UP TO damage and saturation are not the like AVOIDING it altogether.
When looking for and contrasting spa covers, ALL claims associated with R-value of a cover that has foam are absolutely unverified. Foam Thickness and also Foam Density do not have any type of ADDED R VALUE, given that the foam is not created to be applied over a damp setting. Most spa cover dealers repeat specifically the very same numbers and also consequently hot tub proprietors have actually been educated to think the lie. Some dealers utilize some elegant graphs to validate their insurance claims, however the bottom line is those insurance claims could not be in accordance to the ASTM.
R-value testing of materials is finished at room temperature level, as well as doesn’t consider moisture and vapor. In the spa atmosphere, there is hot water as well as great quantities of steamy dampness. Each of which will considerably minimize the R-value of any kind of foam. A spa at 105 degrees will certainly defeat the R-value of any kind of foam examined to make use of in a completely dry application.
Do not allow the R-value of foam be taken into consideration the dimension for spa cover quality. Rather look for a spa cover without any FOAM. Instead, hot tub covers that use air filled chambers as an alternative for rigid foam boards will out preform other, in any kind of examination or genuine hot tub application.

Don’t be tricked 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 and also sewing. It won’t shield as well. It will most definitely still end up being saturated, deformed or broken. It truly was outdated thirty years back.
SpaCap.com spa covers don’t utilize foam panels like the normal rigid foam filled hot tub covers. Instead they utilize air chambers to do the insulating. Aside from being much more reliable, the air chambers do not suck up moisture like every foam-filled cover ever made.
