Yankee Pool Pillow Emerald Series above ground pool cover — 15 ft Round, 9 mil UV‑resistant with sealed seams

The Yankee Emerald Series 15 ft round above ground pool cover is a medium-thick, UV-resistant winterization cover built to protect your pool through extreme cold, heat, and seasonal debris.

Keep leaves, sunlight, and weather from damaging your above ground pool during the off-season with a cover engineered for lasting performance. This 15 ft round cover from Yankee Pool Pillow’s Emerald Series combines a dense 9 mil fabric with reinforced seams, corrosion-resistant hardware, and a molded winch system to lock the cover in place. It’s designed to reflect harmful UV, suppress algae formation with a black underside, and tolerate wide temperature swings so the pool stays cleaner and easier to reopen.

How does this cover stand up to winter weather and debris?

The Emerald Series cover uses a durable 9 mil polyethylene fabric with a 10x10 scrim count for added tear resistance, plus reinforced seam sealing to prevent separation. It’s cold-tested to -10°F and resists degradation from prolonged sun exposure, reducing holes and blowouts during storms.

• 9 mil medium-thick LDPE-coated fabric with a 10x10 scrim for strength
• Reinforced sealed seams to resist splitting under stress
• Black underside to limit light penetration and discourage algae
• Designed to deflect leaves, branches, and snow loads

Will the cover resist UV damage and prevent algae growth?

Yes. The top layer reflects UV rays to slow material breakdown while the black bottom surface reduces light reaching the water, which helps prevent algae blooms during storage. The fabric finish and dense weave together reduce sunlight penetration more effectively than a plain tarp.

• UV-reflective LDPE coating protects fabric life
• Black underside limits water illumination to inhibit overgrowing
• Dense scrim count increases opacity and durability

How secure is the cover when winds, ice, or temperature swings occur?

The Emerald Series includes a steel-core cable routed through rust-resistant metal grommets and tightened with a precision-molded winch for a snug fit. This hardware keeps the cover cinched to the pool’s top rail, reducing movement from wind or ice and helping prevent water accumulation or slippage.

• Steel-core cable resists stretching and holds shape
• Rust-resistant grommets reduce corrosion points
• Precision-molded winch provides reliable tension control
• Fit engineered for round 15 ft above ground pools to minimize sag

How durable is this cover across seasons and temperatures?

This cover is built to handle broad temperature ranges: it remains flexible in frigid conditions down to -10°F (-25°C) and tolerates heat up to about 180°F (80°C) without significant degradation. Those specifications mean it’s more reliable than a simple tarp for seasonal storage and repeated use year after year.

• Cold-tested to -10°F for winter resilience
• Heat-resistant up to 180°F to prevent warping in hot sun
• Dense construction reduces wear from repeated installation

Who is this for: The Yankee Emerald Series 15 ft round cover is aimed at above ground pool owners who want a mid-weight, long-lasting winter cover that balances affordability with robust performance. It’s a good choice for homeowners who need dependable protection against leaves, UV exposure, algae, and seasonal weather without upgrading to professional-grade heavy covers. If you want fewer maintenance tasks in spring and a cover that installs and tightens securely, this model delivers practical, season-to-season reliability.
