EXTRA THICK AND SUPER DURABLE. The key to an effective above ground pool winterizing kit is the material quality. This winter pool cover boasts a 14 × 14 scrim count (the industry’s top standard) and the density of 185 gsm. Also important in pool covers for above-ground pools are the seams: poorly done, they will let dirt through. Our pool cover’s patent-pending sealing technology prevents it and keeps the water inside uncontaminated until spring. PROTECTION FROM SUNLIGHT AND OVERGROWING. When choosing a pool closing kit for above-ground pools, remember that winter sun is deceiving. UV radiation from it doesn’t drop during colder months as much as temperature does, so any materials left outside are at risk of damage. That’s why the cover in our pool closing kit has LDPE coating on it that’s been tested to withstand solar UV radiation. Also, the BLACK UNDERSIDE of the round pool cover won’t let the water overgrow. HIGHLY RESISTANT TO COLD. If you live in a place where winters are bitter, your above-ground pool protection needs to be able to survive low temperatures on top of keeping precipitation and debris out of the pool. Unlike a simpler pool tarp, this swimming pool cover will cope with the cold as bad as −10° F (−25° C). On the other end of its temperature resistance range, the pool wrap shows impressive stats, too: it can handle the heat of up to 180° F (80° C). PREMIUM SAPPHIRE SERIES. Our pool covers, pool water bags, and pool pillows for above-ground pools rank highest on Amazon for a reason: we focus on the critical characteristics like sturdiness and durability, but we also like to add little extras, like the generous 4-foot overlap on this above-ground pool cover to make winterization easier for you. We at Yankee Pool Pillow are dedicated to making helpful and reliable solutions for fellow swimming pool owners: get them and see for yourself. *Pool Pillow is not included and is sold separately.
