Hot Tub Covers and the R-Value

The Myth of R-Value and typical foam filled Swim Spa Covers

R-value is a type of measurement of the ability to withstand 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 warmth storage and also, warmth retention would be the key work of any type of Swim Spa Cover

Many sectors utilizing R-values are managed by FTC requirements. Commercially sold insulation should pass independent examinations developed by American Standards and Screening Approaches (ASTM) so regarding be promoted or marked utilizing their R-Value.

The Misled Masses: As there is no FTC identified independent examination for Swim Spa Covers, So ANY stated R-value stated by a Swim Spa Cover dealership remains in reality an unregulated, unmonitored “analysis” of a given insulation worth. It is open to misstatement as well as misuse, from including the R-value of an air space in between the water and the bottom of the Swim Spa Cover, spacing between the plastic and also the Swim Spa Cover insulation, or merely coldly inflating the fictitious number. Some spa suppliers specify specifically the well-known R-value of the insulation itself, however of course that does not mean that it was checked and endorsed to make use of in Swim Spa Cover applications.

The R-value of the real foam insulation, despite the thickness, is ONLY rated for use in DRY structure applications! Which symbolizes that the R rating of the foam is just appropriate needs to it take place to be used in a wall surface, attic or flooring. Due to the fact that ought to it were to be used in a wet environment, that kind of insulation would fail swiftly.

Foam Thickness as well as Foam Density.

These 2 factors that Swim Spa Cover suppliers declare influence the R-value of Swim Spa Covers, when actually that R ranking itself has nothing to do with the foam when it is utilized in their Swim Spa Covers Really, it is as deceiving as the idea that a taper on the Swim Spa Cover will truly maintain it from getting heavy.

True, the foam thickness and also thickness would have a bearing on the insulation homes In the event the Use of the foam remained in compliance with the made use of an entirely DRY environment.

Regardless if the dealership asserts his Swim Spa Covers are made with the most costly Swim Spa Cover foam (rigid cellular polystyrene thermal insulation) readily available, withstands breakage, vapor absorption as well as chemical damage more than all the others they’ve examined. The fact is, R element is NOT something they examine, as well as WITHSTANDING damage and also saturation are not the same as AVOIDING it altogether.

When seeking and contrasting Swim Spa Covers, ALL insurance claims associated with R-value of Swim Spa Covers that have foam are absolutely dubious. Foam Density and also Foam Thickness do not have any kind of ADDED R WORTH, considering that the foam is not made to be applied over a wet setting. Most Swim Spa Cover dealerships repeat precisely the exact same numbers and as a result swim spa owners have actually been educated to think the lie. Some suppliers employ some expensive charts to substantiate their insurance claims, however the main point is those claims could not be in conformity to the ASTM.

Myth Busted!

R-value testing of materials is completed at room temperature, as well as doesn’t take into account moisture and also vapor. In the spa environment, there is warm water and also excellent amounts of steamy moisture. Each which will significantly minimize the R-value of any kind of foam. A spa at 105 levels will certainly defeat the R-value of any type of foam checked to utilize in a dry application.

Do not permit the R-value of foam be taken into consideration the measurement for swim spa cover quality. Rather look for a Swim Spa Cover without any FOAM. Instead, Swim Spa Covers that use air filled chambers as an alternative for rigid foam boards will certainly out preform any other, in any type of test or genuine Swim Spa Cover application. (Hello, like those from )

Do not be fooled by claims of high density and also weight, vacuum wrapped in sheets of heat bonded polyethylene, sealed in heavy gauge marine grade vinyl, with chemical resistant scrim and sewing. It will not insulate as well. It will certainly still become saturated, warped or broken. It really was outdated thirty years earlier. Swim Spa Covers don’t utilize foam panels like the regular rigid foam filled Swim Spa Covers Rather they utilize air chambers to do the insulating. Other than being much more efficient, the air chambers do not suck up moisture like every foam-filled Swim Spa Cover ever made.
