Cover For a Spa Tub

Introduction

Essentially, the basic factor that you should consider when choosing a cover spa is the location of your spa tub. This is definitely where you live and the prevailing climate in the region. You need to take into consideration amounts of rain, sun, cold and the amount of snow your cover spa will tend to receive. All these weather parameters should be considered each at a time to get value for your money. For instance, if you are located in temperate climatic zones, the basic factor influencing the choice of your cover spa is rain unlike trying to keep your hot water bills low. Other climatic regions require the spa owners to consider a combination of several climatic factors and not just one.

Insulation Efficiency of a Cover Spa

Insulation efficiency of a cover spa is determined by the R-Value. This is simply numerical calculations which guide you on the insulation factor of your spa. Essentially, the higher the insulation factor number of the cover for your spa the more effective your cover spa is in retaining heat in your spa. On the other hand, it offers a guideline on the amount of cold your cover is able to keep off as well ensure you don’t pay more on your heating bill. This insulation factor is basically a function of two factors. That is, the thickness and the density of the foam core of your cover spa.

The foam core density and thickness of the cover of your spa are the major determinant of the effectiveness of the spa cover in heat retention. Actually, you will get spa covers of varying and different thickness and it’s good to shop wisely for your spa cover. In most cases, spa covers will tend to be thicker at the middle than at the edges. This ensures water from the rain runs off the cover by providing an appropriate slope. To get insulation efficiency, you may multiply the times of foam thickness with the R-factor. How thick your spa cover is, is a great determinant on how effective your cover is on insulation. The density of your spa cover is also a factor worthy consideration. The foam cores of spa cover will as well come in varying densities. Common densities are 1.0, 1.5 and 2.0 pounds which is an indicator of the amount of raw material composition per unit of foam used in making the spa cover. Typically, the foam of the cover will tally with the thickness of any given cover density. However, the foam tends to be denser implying that it’s stronger.
