Hot Tub Covers and the R-Value

The Misconception of R-Value and standard foam filled hot tub covers

R-value is a form of dimension of the capacity to withstand warm transfer for products like the fiberglass insulation in your home or maybe the insulating foam in hot tub covers The intent is that, the greater the R-value, the much better the warmth storage space and also, warm retention would be the key task of any kind of hot tub cover.

Most industries making use of R-values are regulated by FTC criteria. Readily offered insulation needs to pass independent tests created by American Requirements and Screening Techniques (ASTM) so regarding be marketed or noted using their R-Value.

The Misled Masses: As there is no FTC identified independent examination for spa covers, So ANY specified R-value specified by a spa cover supplier is in fact an uncontrolled, unmonitored “analysis” of an offered insulation value. It is open to misstatement and also abuse, from adding the R-value of an air space in between the water and also all-time low of the cover, spacing in between the plastic and the cover insulation, or just coldly blowing up the make believe number. Some hot tub dealers specify exclusively the well-known R-value of the insulation itself, but of course that does not suggest that it was examined and backed to use in hot tub cover applications.

The R-value of the actual foam insulation, no matter the density, is ONLY ranked for use in COMPLETELY DRY structure applications! Which signifies that the R ranking of the foam is only appropriate needs to it occur to be used in a wall surface, attic room or floor. Since must it were to be used in a moist environment, that sort of insulation would certainly stop working promptly.

Foam Density and also Foam Thickness.

These two factors that spa cover dealerships assert influence the R-value of spa covers, when as a matter of fact that R score itself has nothing to do with the foam when it is made use of in a hot tub cover. Really, it is as misleading as the idea that a taper on the cover will actually keep it from obtaining hefty.

True, the foam density and also density would certainly have a bearing on the insulation residential properties In case the Usage of the foam were in conformity with the created use of a completely DRY setting.

Regardless if the supplier claims his spa covers are made with one of the most expensive spa cover foam (inflexible mobile polystyrene thermal insulation) offered, stands up to breakage, vapor absorption and also chemical damages more than all the others they have actually examined. The reality is, R variable is NOT something they test, and WITHSTANDING breakage as well as saturation are not the like AVOIDING it completely.

When seeking as well as comparing spa covers, ALL cases associated with R-value of a cover that has foam are totally unverified. Foam Density and Foam Thickness do not have any type of ADDED R VALUE, because the foam is not developed to be used over a wet environment. Most spa cover dealers repeat precisely the exact same numbers as well as as a result hot tub proprietors have been educated to think the lie. Some suppliers employ some fancy charts to confirm their claims, nevertheless the main point is those cases could not be in conformity to the ASTM.

Misconception Damaged!

R-value screening of products is completed at room temperature, as well as doesn’t think about dampness as well as vapor. In the spa environment, there is hot water and good quantities of steamy wetness. Each which will dramatically lower the R-value of any kind of foam. A spa at 105 levels will defeat the R-value of any type of foam tested to make use of in a completely dry application.

Don’t enable the R-value of foam be considered the dimension for spa cover top quality. Instead look for a spa cover without FOAM. Instead, hot tub covers that use air filled chambers as an option for rigid foam boards will certainly out preform other, in any type of examination or real hot tub application. (Hey there, like those from )

Don’t be deceived by claims of high density as well as weight, vacuum wrapped in sheets of heat welded polyethylene, sealed in heavy gauge marine quality plastic, with chemical resistant scrim and sewing. It won’t protect too. It will definitely still end up being saturated, distorted or busted. It genuinely was obsolete thirty years earlier. spa covers don’t use foam panels like the regular rigid foam filled hot tub covers. Instead they utilize air chambers to do the insulating. In addition to being much more effective, the air chambers do not suck up wetness like every foam-filled cover ever made.

Why not go to as well as order a hot tub cover for your spa today and get the next generation of hot tub covers.
