The type of cover that you need to select for your spa depends on your location. The cover needed for a spa located in colder temperatures requires a cover to retain heat. A spa located in warmer temperatures may only need a cover to keep out rain. The biggest factor to consider for a spa cover is insulation used to prevent heat loss.
Function
The function of a spa cover is to preserve heat and lower the cost of operating the unit. The selection of a spa cover will need to serve a specific purpose based on this and other factors. You need to consider a specific style or design that will seen when your spa is not being used.
Shape
The specific design of your unit will dictate the shape of your spa cover. Designs for a spa can be made in the shape of an octagon, be a perfect square, have one cut corner or be a rectangle or round. You will need to select your cover based on the shape of your spa.
Insulation Efficiency
The insulation efficiency is based on a numerical calculation called the R-value. The higher number for the R-value, the better the insulation factor of the cover. A cover with a better insulation factor means a spa will retain heat in the cold for a longer period of time. This will also keep the costs for heating your spa down.
hot tub covers will vary. The density of a standard cover may range from 1 pound to 1.5 pound and up to 2 pound. The pound for the density refers to the amount of raw material that is used when the cover is made. This foam will be the same thickness for each density. This means that a higher foam core density produces a stronger cover.
Foam Core Thickness
The thickness of spa covers will vary based on each product. Spa covers are thinner at the sides that in the middle to allow for rainwater to run off the cover and not pool on top. This is called the slope of the cover. The thicker the foam core the more pronounced the slope.
Additional Information
Some types of spa covers are hinged. This allows you to open one side of your spa without the need for the whole cover to be removed. This is a feature that you need to consider when you are ready to select your spa cover. You can easily research options for a spa cover by looking at various products found on the Internet.
