Hot Tub Covers and the R-Value

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

R-value is a type of dimension of the ability to withstand heat transfer for materials like the fiberglass insulation in your home or possibly the insulating foam in hot tub covers The intent is that, the better the R-value, the much better the warmth storage space and, warm retention would certainly be the main job of any kind of hot tub cover.

The majority of sectors using R-values are controlled by FTC requirements. Readily marketed insulation must pass independent examinations created by American Requirements as well as Screening Methods (ASTM) so as to be advertised or noted utilizing their R-Value.

The Misled Masses: As there is no FTC identified independent test for spa covers, So ANY mentioned R-value specified by a spa cover supplier remains in reality an uncontrolled, unmonitored “analysis” of a given insulation value. It is open to misstatement and misuse, from adding the R-value of an air space in between the water as well as all-time low of the cover, spacing between the plastic and also the cover insulation, or merely blatantly blowing up the fictitious number. Some hot tub dealerships mention solely the well-known R-value of the insulation itself, however naturally that doesn’t suggest that it was examined as well as backed to use in hot tub cover applications.

The R-value of the actual foam insulation, despite the density, is ONLY rated for use in COMPLETELY DRY structure applications! Which signifies that the R score of the foam is only relevant ought to it take place to be used in a wall surface, attic or flooring. Because must it were to be utilized in a damp environment, that sort of insulation would stop working promptly.

Foam Density and also Foam Thickness.

These two factors that spa cover dealers assert affect the R-value of spa covers, when as a matter of fact that R ranking itself has nothing to do with the foam when it is used in a hot tub cover. Really, it is as misleading as the idea that a taper on the cover will truly keep it from obtaining hefty.

Real, the foam thickness and also thickness would certainly have a bearing on the insulation properties In the event the Use of the foam remained in conformity with the designed use a completely DRY atmosphere.

No matter if the dealer declares his spa covers are made with one of the most costly spa cover foam (rigid mobile polystyrene thermal insulation) readily available, withstands damage, vapor absorption and also chemical damage more than all the others they have actually tested. The reality is, R factor is NOT something they evaluate, and WITHSTANDING damage and saturation are not the same as PREVENTING it altogether.

When searching for and also comparing spa covers, ALL insurance claims connected with R-value of a cover that has foam are completely unsubstantiated. Foam Density and Foam Thickness do not have any ADDED R VALUE, considering that the foam is not made to be applied over a damp environment. Many spa cover suppliers repeat specifically the exact same numbers as well as subsequently hot tub proprietors have actually been educated to think the lie. Some dealers employ some expensive graphs to validate their cases, nonetheless the bottom line is those insurance claims could not remain in conformity to the ASTM.

Misconception Broken!

R-value screening of materials is completed at room temperature level, as well as does not think about dampness and vapor. In the spa setting, there is warm water and excellent quantities of steamy moisture. Each of which will considerably lower the R-value of any type of foam. A spa at 105 degrees will defeat the R-value of any foam checked to utilize in a dry application.

Don’t enable the R-value of foam be considered the dimension for spa cover top quality. Rather 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 any other, in any kind of test or genuine hot tub application. (Hello, like those from SpaCap.com )

Don’t be mislead by claims of high thickness and also weight, vacuum wrapped in sheets of heat welded polyethylene, secured in hefty gauge marine quality plastic, with chemical resistant scrim and sewing. It won’t insulate too. It will absolutely still come to be saturated, deformed or damaged. It genuinely was outdated thirty years ago.

SpaCap.com spa covers do not use foam panels like the common rigid foam filled hot tub covers. Rather they utilize air chambers to do the insulating. Aside from being extra efficient, the air chambers don’t suck up moisture like every foam-filled cover ever made.
