Hot Tub Covers and the R-Value

The Myth of R-Value as well as conventional foam filled Swim Spa Covers

R-value is a kind of dimension of the capability to resist warm transfer for products like the fiberglass insulation in your house or perhaps the protecting foam in swim spa covers. The intent is that, the greater the R-value, the much better the warm storage and also, warmth retention would be the main task of any Swim Spa Cover

Many sectors making use of R-values are managed by FTC criteria. Commercially offered insulation has to pass independent tests produced by American Criteria as well as Screening Methods (ASTM) so regarding be promoted or marked using their R-Value.

The Misled Public: As there is no FTC recognized independent examination for Swim Spa Covers, So ANY stated R-value specified by a Swim Spa Cover dealer remains in fact an unregulated, unmonitored “analysis” of a given insulation worth. It is open to misrepresentation and misuse, from adding the R-value of an air space between the water and the bottom of the Swim Spa Cover, spacing between the vinyl and also the Swim Spa Cover insulation, or merely coldly inflating the fictitious number. Some spa dealerships mention solely the recognized R-value of the insulation itself, but obviously that doesn’t mean that it was checked and also recommended to utilize in Swim Spa Cover applications.

The R-value of the actual foam insulation, regardless of the density, is ONLY rated for usage in DRY structure applications! Which signifies the fact that the R score of the foam is only applicable must it happen to be applied in a wall, attic room or flooring. Due to the fact that must it were to be made use of in a wet atmosphere, that sort of insulation would certainly fall short swiftly.

Foam Thickness as well as Foam Density.

These 2 elements that Swim Spa Cover dealers declare impact the R-value of Swim Spa Covers, when as a matter of fact that R rating itself has nothing to do with the foam when it is used in their Swim Spa Covers In fact, it is as deceiving as the concept that a taper on the Swim Spa Cover will actually keep it from getting heavy.

True, the foam density and density would certainly have a bearing on the insulation residential properties In case the Use of the foam remained in compliance with the designed use of a completely DRY environment.

Regardless if the supplier declares his Swim Spa Covers are made with one of the most expensive Swim Spa Cover foam (inflexible cellular polystyrene thermal insulation) readily available, resists damage, vapor absorption as well as chemical damage more than all the others they have actually checked. The reality is, R variable is NOT something they examine, as well as RESISTING breakage and saturation are not the same as PREVENTING it completely.

When looking for and contrasting Swim Spa Covers, ALL insurance claims associated with R-value of Swim Spa Covers that have foam are completely dubious. Foam Density and also Foam Thickness do not have any ADDED R WORTH, given that the foam is not designed to be applied over a wet environment. Many Swim Spa Cover suppliers repeat specifically the very same numbers and consequently swim spa owners have actually been educated to think the lie. Some dealers use some fancy graphs to substantiate their cases, nevertheless the main point is those insurance claims can not be in accordance to the ASTM.

Myth Busted!

R-value screening of products is finished at room temperature level, as well as does not consider wetness as well as vapor. In the spa atmosphere, there is warm water and good amounts of steamy wetness. Each of which will significantly lower the R-value of any kind of foam. A spa at 105 degrees will certainly defeat the R-value of any foam tested to use in a dry application.

Do not allow the R-value of foam be taken into consideration the dimension for swim spa cover top quality. Instead search for a Swim Spa Cover with NO FOAM. Instead, Swim Spa Covers that use air filled chambers as an alternative for rigid foam boards will out preform other, in any test or genuine Swim Spa Cover application. (Hello there, like those from )

Do not be deceived by claims of high thickness and weight, vacuum wrapped in sheets of heat bonded polyethylene, secured in hefty gauge marine grade plastic, with chemical resistant scrim and sewing. It will not insulate also. It will most definitely still come to be saturated, deformed or damaged. It absolutely was outdated thirty years back. Swim Spa Covers don’t utilize foam panels like the regular rigid foam filled Swim Spa Covers Instead they make use of air chambers to do the insulating. Other than being more efficient, the air chambers do not suck up wetness like every foam-filled Swim Spa Cover ever made.
