Blue Wave Arctic Armor 20x40 ft Rectangular In-Ground Pool Winter Cover — Heavy-Duty Solid with Heat-Sealed Seams

Blue Wave Arctic Armor 20x40 is a heavy-duty solid winter cover designed to shield rectangular in-ground pools from leaves, rain, snow, and debris so your pool opens cleaner in spring.

Closing a rectangular in-ground pool for the cold months doesn’t need to mean extra spring cleanup or a green pool. The Blue Wave Arctic Armor 20x40 winter cover uses a dense 10x12 scrim woven polyethylene panel with reinforced, heat-sealed seams to form a tough, weather-resistant barrier. Its solid construction keeps most debris and sunlight out while sitting flat across the pool; water that gathers on top is normal and helps stabilize the cover through storms.

How does this cover keep debris and sunlight from degrading my pool over winter?

The Arctic Armor cover is made from a tightly woven 10x12 scrim polyethylene that blocks leaves, twigs, and most fine debris. Heat-sealed seams reduce splitting and create stronger joints, while the black underside limits light penetration that encourages dirt and algae buildup.

• Solid panel construction prevents debris from passing through
• Black underside reduces sunlight to slow organics growth
• Heat-sealed seams lock out water and resist seam failure

What hardware and fastening options are included to secure a 20x40 cover?

This cover fits 20x40-ft rectangular in-ground pools and includes a vinyl-coated cable plus a metal winch that thread through grommets spaced every 2 feet. For added stability without drilling into the deck, sewn water tube loops every 4 feet accept water tubes (sold separately) to hold the cover down.

• Grommets every 2 ft accept the included cable and metal winch
• Sewn perimeter loops every 4 ft for water tube anchoring (tubes not included)
• Approx. 5 ft overlap on all sides for full edge coverage

Can I leave water on the cover, and how should I handle heavy snow or pooled water?

Yes — because this is a solid winter cover, water will collect on the surface rather than drain through. A thin layer of water helps weigh the cover down against wind; after heavy snow or storms you can remove excess with a cover pump or sweep snow from the pool edge with a soft-bristle broom.

• Standing water on top is normal and helps stabilize the cover
• Use a cover pump (sold separately) to remove excess water safely
• Clear heavy snow from the edges to prevent seam strain and dumping

Is this cover a safety cover I can walk on?

No. The Arctic Armor winter cover is a debris and weather cover, not a safety or load-bearing surface. It should never support people, animals, or heavy gear — walking on it risks damage and voids its intended use.

• Not rated for foot traffic or weight-bearing use
• Designed solely to block debris, sun, and precipitation
• Follow manufacturer guidance to avoid stretching or tearing
