Pool Mate Winter Pool Cover 20 x 40 ft for Inground Pools — Blue UV-Coated Heavy-Duty Dura-Guard

The Pool Mate 20 x 40 ft Classic Dura-Guard Winter Pool Cover is a solid, heavy-duty polyethylene cover designed to protect inground pools from winter elements while floating on the water with a five-foot overlap for easier installation.

Built for seasonal pool shutdowns, this Pool Mate cover is a non-porous winter barrier that keeps snow, ice and large debris off the pool surface. It uses a thick woven polyethylene scrim and heat-sealed seams for strength and longevity, and the blue UV-coated topside helps resist sunlight degradation during storage and off-season exposure. The cover ships with reinforced water-tube loops but water weights are sold separately; the design expects the cover to rest lightly on the water rather than being tensioned tight.

How does this cover protect my pool through winter?

The solid material blocks precipitation and large debris from entering the pool, so maintenance chores in spring are reduced. Heat-welded seams and a heavier-than-standard fabric help the sheet resist tears from ice or wind-borne branches.

• Solid, non-porous polyethylene prevents water from passing through the cover
• 18% heavier construction than typical industry standards for added durability
• Heat-sealed seams reduce seam failure risk
• Blue UV-coated surface slows sun damage while stored or partially exposed

How do I install the Pool Mate winter cover safely?

Installation relies on vinyl water weights that fit through the perimeter loops to hold the cover down; no other fastening methods are recommended. The cover includes a five-foot overlap so it can float and be dressed around pool edges—order a larger size if you have steps or raised features.

• Use only vinyl water tubes through supplied loops for secure anchoring
• Leave the cover loose enough to float but not bag excessively on top of pool water
• Fold any excess material under the water weights to avoid cluttering the deck
• Pad exposed corners or deck contact points with soft material to prevent abrasion

What are the material specs and warranty?

The Classic Dura-Guard is woven polyethylene with an 8 x 8 scrim and a material weight of roughly 2.36 oz/yd² (80 g/m²), which are simple, measurable indicators of expected durability. Pool Mate backs this design with a 10-year warranty and draws on decades of experience manufacturing pool covers.

• Woven 8 x 8 scrim for a balanced strength-to-weight ratio
• Material weight ~2.36 oz/yd² (80 g/m²) for season-long protection
• Heat-sealed seams to strengthen joins and reduce leaks
• 10-year warranty from the manufacturer

Will this cover work for pools with unusual shapes or features?

The cover is sized for standard rectangular inground pools but includes extra overlap to accommodate minor irregularities. If your pool has built-in steps, spa seats, or other protrusions, choose the next larger cover to ensure the sheet can float without stress.

• Ships with a five-foot overlap beyond the pool footprint for easier fit
• Recommended to upsell a size when steps or ledges protrude
• Designed to float freely on the water rather than be stretched taut
• Loops positioned around the perimeter for water-weight installation

Who this cover is for: Pool owners who close their inground pools for the off-season and want a robust, solid-surface winter cover that keeps out precipitation and bulk debris. It suits owners who prefer a floating, water-weight installation and those with standard rectangular pools or modestly irregular shapes—if your pool has prominent steps or attached spas, choose a larger size to ensure a proper, low-stress fit.
