Robelle 18 ft Winter Pool Cover for Above-Ground Pools — Dove Gray/Black Solid Industrial 14x12 Scrim

Robelle's 18 ft Industrial Ultra Winter Pool Cover is a solid, heavy-duty winter cover for 18 ft above-ground pools that uses 14 x 12 scrim polyethylene and a 4 ft overlap to deliver long-lasting seasonal protection.

If you need a winter cover built to resist snow, ice and wind for the off-season, this Industrial-Grade Robelle cover is engineered for durability. It is a solid (non-permeable) cover that stops water from passing through the fabric, ships with a winch and cable for perimeter attachment, and carries a 20-year warranty. The dove gray top and black underside, heavy material weight and dense scrim count combine to give stronger puncture and tear resistance compared with typical consumer covers.

How does this cover keep winter debris and ice away from my pool?

The Robelle Ultra Winter Cover is a solid panel that sheds snow and blocks leaves and sunlight to slow algae growth. Because water cannot pass through the material, debris stays on top where it’s manageable until spring removal.

• Solid polyethylene fabric prevents water passage and limits debris entry.
• Dove gray top sheds light and snow; black underside adds UV stability.
• Designed to float loosely on the water to reduce stress from ice formation.

What makes the material stronger than standard winter covers?

Strength comes from two measurable factors: material weight and scrim count. Robelle’s cover uses 4.5 oz./yd2 polyethylene woven with a 14 x 12 scrim, which increases tear resistance and longevity versus thinner, lower-scrim competitors.

• 4.5 oz./yd2 industrial polyethylene for higher puncture resistance.
• 14 x 12 scrim (threads per inch) for reinforced weave durability.
• Constructed 125% heavier than industry standard for longer service life.

How do I install and secure the 18 ft cover on an above-ground pool?

Installation uses the included winch and cable to tighten the cover through perimeter grommets; the cover also includes a four-foot overlap to ease installation. For pools with decks, use vinyl water weights on top of the cover and run cable under the deck where possible.

• Includes winch and cable; secure through grommets around the perimeter.
• 4 ft overlap (cover measures 22 ft including overlap) simplifies fitting.
• Optional cover clips, cover wrap, and water weights recommended for extra security.

What should I consider before ordering this cover for my pool?

Measure your pool top rail and compare to the stated pool size plus overlap: Robelle recommends bumping up one size for very large top rails so the cover floats without excessive stress. This cover is intended for offseason winter use only and is not a swimming-season debris cover.

• Designed for traditional above-ground pools with a standard top rail.
• If you have an oversized top rail, choose the next larger cover size.
• Not intended as a summer debris cover; use only during the off-season.

Who this cover is for: Pool owners who want a rugged, long-lasting winter solution—especially those in climates with heavy snow, strong winds or frequent freeze/thaw cycles. If you prioritize a high scrim count, heavier polyethylene and a proven warranty, the Robelle 18 ft Industrial Ultra Winter Pool Cover is tailored for above-ground pool owners seeking professional-grade seasonal protection.
