Hot Tub Covers and the R-Value

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

R-value is a type of measurement of the capability to resist heat transfer for materials like the fiberglass insulation in your house or possibly the insulating 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 key work of any type of hot tub cover.

Most markets using R-values are controlled by FTC standards. Readily sold insulation needs to pass independent tests produced by American Requirements and Testing Approaches (ASTM) so about be promoted or noted using their R-Value.

The Misled Masses: As there is no FTC recognized independent examination for spa covers, So ANY mentioned R-value mentioned by a spa cover dealer remains in reality an unregulated, unmonitored “interpretation” of a provided insulation value. It is open to misrepresentation and also abuse, from including the R-value of an air space between the water and all-time low of the cover, spacing in between the vinyl as well as the cover insulation, or just coldly inflating the fictitious number. Some hot tub suppliers specify exclusively the recognized R-value of the insulation itself, yet naturally that doesn’t indicate that it was examined as well as recommended to make use of in hot tub cover applications.

The R-value of the real foam insulation, no matter the thickness, is ONLY rated for use in COMPLETELY DRY structure applications! Which indicates the fact that the R ranking of the foam is just applicable must it take place to be applied in a wall, attic room or flooring. Due to the fact that must it were to be used in a moist setting, that sort of insulation would stop working swiftly.

Foam Thickness and Foam Thickness.

These 2 aspects that spa cover suppliers claim impact 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 misinforming as the suggestion that a taper on the cover will really keep it from obtaining hefty.

Real, the foam thickness as well as density would have a bearing on the insulation homes In case the Use of the foam remained in compliance with the created use of a totally DRY atmosphere.

Regardless if the supplier declares his spa covers are made with one of the most costly spa cover foam (rigid cellular polystyrene thermal insulation) available, resists damage, vapor absorption and chemical damage greater than all the others they have actually tested. The fact is, R factor is NOT something they test, as well as STANDING UP TO damage as well as saturation are not the like PREVENTING it entirely.

When looking for and also comparing spa covers, ALL claims connected with R-value of a cover that has foam are absolutely unsubstantiated. Foam Thickness and Foam Thickness do not have any kind of ADDED R VALUE, given that the foam is not made to be used over a wet atmosphere. A lot of spa cover suppliers repeat specifically the very same numbers and also subsequently hot tub proprietors have been educated to think the lie. Some dealers use some expensive graphs to substantiate their cases, nevertheless the main point is those insurance claims can not be in conformity to the ASTM.

Misconception Broken!

R-value testing of products is completed at room temperature, and also doesn’t think about dampness as well as vapor. In the spa environment, there is warm water and also excellent quantities of steamy dampness. Each which will substantially reduce the R-value of any type of foam. A spa at 105 levels will certainly defeat the R-value of any foam examined to use in a dry application.

Don’t allow the R-value of foam be thought about the measurement for spa cover quality. Rather search for a spa cover without FOAM. Instead, hot tub covers that use air filled chambers as an alternative for rigid foam boards will certainly out preform any other, in any type of examination or real hot tub application. (Hello, like those from )

Don’t be tricked by claims of high thickness as well as weight, vacuum wrapped in sheets of heat welded polyethylene, sealed in heavy gauge marine grade vinyl, with chemical resistant scrim and stitching. It won’t insulate too. It will most definitely still become saturated, deformed or damaged. It really was out-of-date thirty years earlier. spa covers do not make use of foam panels like the common rigid foam filled hot tub covers. Rather they utilize air chambers to do the insulating. Aside from being extra reliable, the air chambers do not suck up dampness like every foam-filled cover ever made.

Why not go to and order a hot tub cover for your spa today and obtain the future generation of hot tub covers.
