Hot Tub Covers and the R-Value

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

R-value is a type of measurement of the capacity to resist warmth transfer for materials like the fiberglass insulation in your home or maybe the shielding foam in hot tub covers The intent is that, the better the R-value, the much better the warmth storage space and, warmth retention would be the primary work of any type of hot tub cover.

A lot of sectors utilizing R-values are regulated by FTC requirements. Commercially sold insulation must pass independent tests created by American Standards and also Screening Techniques (ASTM) so as to be marketed or noted using their R-Value.

The Misled Publics: As there is no FTC acknowledged independent examination for spa covers, So ANY specified R-value stated by a spa cover dealership is in truth an uncontrolled, unmonitored “analysis” of an offered insulation worth. It is open to misrepresentation and also misuse, from adding the R-value of an air space between the water and also all-time low of the cover, spacing in between the plastic and also the cover insulation, or just blatantly inflating the make believe number. Some hot tub dealerships specify specifically the recognized R-value of the insulation itself, however certainly that does not indicate that it was checked and supported to utilize in hot tub cover applications.

The R-value of the actual foam insulation, despite the thickness, is ONLY ranked for usage in COMPLETELY DRY building applications! Which signifies the fact that the R score of the foam is only appropriate needs to it take place to be applied in a wall, attic room or floor. Because should it were to be utilized in a damp atmosphere, that kind of insulation would certainly stop working promptly.

Foam Density and Foam Density.

These two aspects that spa cover suppliers claim influence the R-value of spa covers, when in fact that R ranking itself has nothing to do with the foam when it is used in a hot tub cover. In fact, it is as misguiding as the concept that a taper on the cover will truly keep it from getting heavy.

True, the foam density as well as density would have a bearing on the insulation residential properties In case the Usage of the foam remained in conformity with the made use of an entirely DRY atmosphere.

No matter if the supplier declares his spa covers are made with one of the most expensive spa cover foam (inflexible mobile polystyrene thermal insulation) available, stands up to damage, vapor absorption as well as chemical damage more than all the others they have actually checked. The truth is, R variable is NOT something they examine, and RESISTING damage and also saturation are not the like AVOIDING it completely.

When looking for and contrasting spa covers, ALL cases connected with R-value of a cover that has foam are totally unsubstantiated. Foam Density and also Foam Density do not have any type of ADDED R VALUE, because the foam is not designed to be applied over a wet environment. The majority of spa cover suppliers repeat precisely the exact same numbers and consequently hot tub proprietors have been educated to believe the lie. Some suppliers utilize some elegant charts to corroborate their insurance claims, however the bottom line is those insurance claims can not remain in accordance to the ASTM.

Myth Broken!

R-value testing of materials is finished at room temperature, and also does not take into account dampness as well as vapor. In the spa setting, there is warm water and great quantities of steamy moisture. Each which will substantially decrease the R-value of any foam. A spa at 105 degrees will defeat the R-value of any kind of foam checked to make use of in a dry application.

Don’t allow the R-value of foam be taken into consideration the measurement for spa cover quality. Rather search for a spa cover with NO FOAM. Instead, hot tub covers that use air filled chambers as a choice for rigid foam boards will out preform other, in any type of test or genuine hot tub application.

Do not be mislead by claims of high thickness as well as weight, vacuum wrapped in sheets of heat welded polyethylene, secured in heavy gauge marine quality plastic, with chemical resistant scrim and stitching. It will not shield as well. It will definitely still come to be saturated, deformed or damaged. It truly was outdated thirty years earlier.

SpaCap.com spa covers do not make use of foam panels like the normal rigid foam filled hot tub covers. Instead they make use of air chambers to do the insulating. Aside from being a lot more effective, the air chambers do not suck up dampness like every foam-filled cover ever made.
