Robelle Winter Pool Cover 18 x 36 ft — Heavy-Duty Solid Inground Cover, 10-Year Warranty

This Super Winter Pool Cover is a robust, solid-sheet cover built from heavy-duty polyethylene with an 8 x 8 scrim and a material weight of 2.36 oz./yd². Engineered to sit loosely on the water with a five-foot factory overlap, the cover resists punctures and stretching better than lighter covers. It pairs an imperial blue topside with a black underside and comes with sewn loops for vinyl water weights (sold separately). Backed by a 10-year warranty, the Robelle cover is intended specifically for off-season pool protection rather than summer debris use.

How does this cover stand up to winter weather?

The Robelle Super Winter Cover uses a dense scrim weave and heavier polyethylene to deliver enhanced tensile strength and longer wear life compared with thinner covers. Being a solid cover, it prevents water from passing through the material, limiting direct contamination of pool water with falling debris during the off-season. It’s built to resist snow and ice weight when properly installed with water weights around the perimeter.

• 8 x 8 scrim construction for improved tear resistance.
• 2.36 oz./yd² polyethylene for thicker, more durable fabric.
• Solid design prevents water transmission through the material.
• Designed to float on water to distribute winter loads evenly.

What size should I order and how is it installed?

Order by your pool’s listed size (18 x 36 ft) but remember the cover includes a five-foot overlap—overall cover dimensions are 23 x 41 ft. If your pool has steps, seating ledges, or other protrusions, choose the next larger size so the cover floats freely without excessive stress. Installation uses vinyl water weights threaded through sewn loops around the perimeter; no other fastening method is recommended.

• Includes five-foot overlap—overall cover 23 x 41 ft.
• Choose larger size if pool has steps or irregular shapes.
• Sewn loops accept vinyl water weights (sold separately) for secure flotation.
• Fold excess material under weights; pad exposed corners to prevent abrasion.

How durable is the material and what does the warranty cover?

Durability is determined by the scrim count (threads per square inch) and material weight; with an 8 x 8 scrim and 2.36 oz./yd² polyethylene, this cover is constructed about 18% heavier than typical industry standards. These specifications reduce the chance of tearing and extend service life when used as intended. Robelle backs this cover with a 10-year warranty to protect against manufacturing defects.

• Material is 18% heavier than common alternatives for longer life.
• Scrim and fabric weight minimize stretching and punctures.
• 10-year warranty covers manufacturing defects under normal off-season use.
• Recommended maintenance: keep cover floating and use padding at contact points.

Can I use this cover during the swimming season?

No—this product is intended for winter/off-season protection only. It is a solid cover that will not perform as a debris cover designed for regular summer use, and its installation method (water weights) is optimized for long-term static placement rather than frequent removal and replacement.

• Not intended as a summertime debris cover.
• Optimized for long-term winter installation with water weights.
• Frequent on/off use may stress seams and loops over time.
• Store and dry before folding to extend life between seasons.

Who is this for: The Robelle 18 x 36 ft Heavy Duty Super Winter Pool Cover is aimed at inground pool owners who need a reliable, solid winter cover built for durability and easy installation. Choose this cover if you value a thicker fabric with a high scrim count, want the convenience of generous factory overlap, and plan to install with vinyl water weights for secure, season-long protection. If your pool has steps or unique shapes, consider sizing up to ensure a comfortable, floating fit.
