After proper sanitization and water balance, your spa cover itself is the single most critical piece of equipment to keep your hot tub water clean and to keep your energy bill at a reasonable level. Saving money on heating costs means properly insulating your tub, and that is what good insulating spa covers achieve. This is why we have created an article on Sunstar hot tub covers which are the best hot tub cover.
Heat rises, and just like in your home, most heat loss in a hot tub goes directly up. By sitting just above the steaming water, a well-made hot tub cover provides proper insulation to help trap the heat inside. A problem that arises from all the warm water vapour is that the foam core of a spa cover can eventually become saturated, as water molecules work their way into the millions of tiny hollow spaces inside the foam.
When insulating foam becomes wet, it loses almost all of its R-value. While there is no such thing as a waterproof hot tub cover, this article will reveal the best Sunstar hot tub covers which are believed to have the most water-resistant cores ever.
Why Sunstar Hot Tub Covers?
There are many components that contribute to the superior quality of Sunstar hot tubs covers. All are made using only virgin foam cores. We understand that many other manufacturers use regrind foam to help lower their costs. We do not. Virgin foam may be more expensive initially but in the long run, it will actually save money for the consumer by providing a stronger and more energy-efficient cover.
This EPS foam (expanded polystyrene) has the added advantage of containing no CFC’s and it can even be recycled. You can break it down and mix it with your garden soil. Given the environmental issues we now face, Sunstar’s goal is not only to provide you with the best product they can but also to do everything they can to minimize waste and pollution.
Sunstar hot tub covers produce a wide range of spa covers to fit your everyday needs. The quality of our product really gives our customers an edge up against competitors with our friendly customer service and dependability. Sunstar uses virgin foam cores, marine-grade vinyl, and a vapour seal that maintains your tubs heat.
Some of these are reasons for Sunstar hot tub covers importance:
- Sunstar comes with an Antaeus 200 Vapor Seal, made from an exclusive plastic that is more effective at reducing the amount of steam escaping from your hot tub. Anytime you see steam escaping from a hot tub cover, you’re seeing dollar signs going with it. Antaeus 200 Vapor Seal has terrific strength, flexibility, transparency, and scalability.
- Sunstar’s patent-pending centre seal prevents heat from escaping, reducing heat loss and your electric bill!
- Higher standard. Sunstar’s lids meet the ASTM Cover Standard like other manufacturers, but they are also independently UL Classified.
- Other manufacturers use vinyl that is not UV or mildew resistant & contains no plasticizers. That equals vinyl that rips easily, cracks easily and ages quickly. Sunstar only uses marine-grade vinyl for superior performance and longevity.
- Sunstar reinforces every internal stress point, including hinge, handles, straps, corners, and skirt – a total of 28 locations.
Let\’s look at a few effective tips to keep your hot tub cover in one piece during winter:
- Hose off the cover. Wipe it down with a clean cloth or soft sponge. Repeat until it’s fairly clean. Spray on a non-abrasive cleaner like Simple Green and rinse.
- Aerospace 303 Protectant keeps the vinyl supple and prevents drying during harsh winter weather. It’s like sunscreen, protecting against sun damage to the vinyl, and it repels dust, dirt and stains (Armor All seals the vinyl and hastens to age). Even if you don’t condition every month, at least give your cover a treatment before the snow and ice come.
- When the snow and icefall, sweep off the accumulation with a soft broom to preserve the foam cores without harming the vinyl. Never use a rake.
- Vinyl doesn’t stretch, even though it’s rated not to crack at temperatures well below zero, so be gentle with the straps and handles.
- If your tub is on a roof, bluff, seashore, mountain or another high exposure spot, or your winter storms are windy, lock down the cover with Windstraps. They’re padded, easy to install across the top, and you won’t have to worry when the wind blows.
