You ought to keep two things in mind when looking for a new hot tub cover: the location and your climate. If you use your spa all year, you need to search for a cover that will substantially lower your heating bills, especially if you live in a place with severe winter months. Think for a minute about the amounts of cold and warm, rain and snow, and possible other stormy weather patterns that your cover will be exposed to. Each of these details is a factor in selecting correct hot tub covers, to acquire the best value for your dollar and to reduce your monthly running cost.
It's frequently misunderstood that the thickness of the covers foam cores is the most important aspect for keeping your heating bill low. This is not really true. It is a MUCH more essential aspect to add to the thickness of the foam core in the hot tub cover. This is due to the way the insulation value, also called the "R-value" is determined. The R-value is a factor of the insulating value of the foam times the thickness of the foam cores in the spa cover. The R-value per dollar is greater for a thicker cover than a cover with more dense foam.
People often choose to replace their cover after it becomes increasingly heavy and waterlogged, making for a hassle to even get into the tub. In the industry, the water logging protection element of the cover is termed the vapor barrier. It is known as a vapor barrier because the vapor from the warm water in the hot tub is what will ultimately get inside the cover. It is not, as often believed, to keep the rain and snow out of your cover.
