Hot Tub Covers and the R-Value

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

R-value is a form of dimension of the capability to resist warm transfer for products like the fiberglass insulation in your residence or possibly the shielding foam in hot tub covers The intent is that, the better the R-value, the better the warmth storage space and, warm retention would be the main work of any hot tub cover.

A lot of markets using R-values are regulated by FTC standards. Commercially marketed insulation needs to pass independent examinations created by American Criteria and Screening Methods (ASTM) so regarding be advertised or marked using their R-Value.

The Misled Publics: As there is no FTC acknowledged independent examination for spa covers, So ANY stated R-value specified by a spa cover dealership is in reality an unregulated, unmonitored “analysis” of a provided insulation worth. It is open to misstatement and also misuse, from adding the R-value of an air space between the water as well as the bottom of the cover, spacing between the plastic as well as the cover insulation, or merely coldly pumping up the fictitious number. Some hot tub dealerships mention solely the recognized R-value of the insulation itself, however obviously that doesn’t suggest that it was examined as well as backed to utilize in hot tub cover applications.

The R-value of the real foam insulation, regardless of the density, is ONLY rated for usage in COMPLETELY DRY building applications! Which signifies that the R ranking of the foam is only appropriate needs to it occur to be applied in a wall, attic or floor. Since ought to it were to be utilized in a damp environment, that kind of insulation would certainly stop working swiftly.

Foam Density as well as Foam Thickness.

These two factors that spa cover suppliers claim affect 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 utilized in a hot tub cover. Really, it is as misguiding as the suggestion that a taper on the cover will really maintain it from obtaining hefty.

True, the foam thickness as well as density would certainly have a bearing on the insulation homes In the event the Use of the foam were in conformity with the created use of a completely DRY environment.

Regardless if the supplier claims his spa covers are made with the most costly spa cover foam (rigid cellular polystyrene thermal insulation) available, withstands breakage, vapor absorption and chemical damages greater than all the others they’ve evaluated. The fact is, R variable is NOT something they check, and RESISTING damage and saturation are not the like PREVENTING it entirely.

When seeking as well as contrasting spa covers, ALL cases connected with R-value of a cover that has foam are entirely unsubstantiated. Foam Density as well as Foam Thickness do not have any kind of ADDED R VALUE, since the foam is not designed to be used over a damp atmosphere. Many spa cover dealerships repeat precisely the very same numbers as well as subsequently hot tub proprietors have been trained to believe the lie. Some suppliers employ some expensive graphs to confirm their cases, nevertheless the main point is those claims can not be in accordance to the ASTM.

Misconception Busted!

R-value screening of materials is finished at room temperature, as well as doesn’t take into consideration moisture and vapor. In the spa environment, there is hot water and also great quantities of steamy wetness. Each of which will considerably decrease the R-value of any type of foam. A spa at 105 levels will defeat the R-value of any kind of foam evaluated to use in a completely dry application.

Don’t allow the R-value of foam be thought about the dimension for spa cover top quality. Rather search for a spa cover without FOAM. Instead, hot tub covers that use air filled chambers as a choice for rigid foam boards will certainly out preform other, in any test or genuine hot tub application. (Hi, like those from SpaCap.com )

Don’t be tricked by claims of high thickness and weight, vacuum wrapped in sheets of heat bonded polyethylene, sealed in hefty gauge marine grade vinyl, with chemical resistant scrim and sewing. It will not shield also. It will absolutely still become saturated, distorted or broken. It absolutely was obsolete thirty years back.

SpaCap.com spa covers do not make use of foam panels like the typical rigid foam filled hot tub covers. Rather they make use of air chambers to do the insulating. In addition to being more effective, the air chambers do not suck up moisture like every foam-filled cover ever made.
