18′ Round Frostguard Premium Winter Cover With FULL 8yr Replacement Warranty

Stop replacing flimsy covers every spring. Protect your 18-foot round pool with winter defense built to withstand brutal freeze cycles, heavy snowpack, and high winds.

The Frostguard Premium Winter Cover is constructed from an unrippable, 100% continuous-filament polyethylene scrim. With zero fillers or weak points, this commercial-grade weave delivers up to five times the puncture and tear resistance of standard covers.

Its dual-layer construction works around the clock: the UV-treated royal blue top shield deflects sun rot, while the black light-blocking underside starves algae of sunlight, ensuring you open to clear water in the spring.

Why Pool Owners Rely on Frostguard:

• True Extreme-Cold Durability: Rated down to -30°F so the material will not crack, shatter, or become brittle under freezing ice sheets.
• Full 4-Foot Overlap: Generously sized with 4 feet of extra material beyond your 18-foot waterline, ensuring plenty of slack for winter pillows and a secure drop over the top rail.
• Complete Tie-Down System Included: Ships with a heavy-duty vinyl-coated steel perimeter cable and a metal ratchet winch to lock the cover tightly against the pool wall.
• Zero-Algae Black Underside: Completely blocks light transmission to prevent costly springtime chemical cleanups.
• Backed by an 8-Year Warranty: Tested for long-term seasonal performance so your backyard investment stays protected year after year.
