Spa covers come in a huge variety of shapes and styles. Each style has it's own characteristics that may make it the correct spa cover for your spa. It is important to note that the cover of your spa will determine to a great extent how much heat loss your spa has, and as a result how much electricity it requires to maintain the water temperature that you have selected. Make sure that if you are energy concious or live in a colder climate that you choose a spa cover with a good R value as well as one that is asthetically pleasing.
Types of Spa Covers
Roll up spa covers
Roll up spa covers offer a couple of unique advantages over the traditional lift off covers. The main advantage is that the cover simply rolls up for easy removal and rolls easily back into place when you are finished with your spa. This type of spa cover is usually made of a thin insulating layer (usually not the best for energy efficiency) and a decorative layer (often wood slats to match your porch or deck). Due to it's sturdy nature, the type of spa cover is quite durable and will usually outlast a traditional spa cover.
Insulating spa covers
A good insulating spa cover can often pay for itself in the first 6 months of use. Because heat rises, your spa cover is all that prevents the heat of your spa from escaping, and consequently from you paying to heat the neighborhood with your spa. Make sure that you choose a cover with a high R value. (An r value is a measure of resistance to heat flow. Insulation materials have tiny pockets of trapped air. These pockets resist the transfer of heat through material. The ability of insulation to slow the transfer of heat is measured in R-values. The higher the R-value, the better the insulation material's ability to resist the flow of heat through it.)
It is important when looking at insulating spa covers to determine the density of the foam. The density should be higher as the spa cover gets thinner. This will provide strength to thinner spa covers. As the spa cover gets thicker, the density can be lower since the extra thickness will provide strength. A lower density foam will also make a thick cover lighter and easier to move on and off the spa.
