Robelle Heavy Duty Super Winter Pool Cover 25 x 45 ft — Solid Non-Permeable, 10-Year Warranty, Imperial Blue/Black

Robelle 25 x 45 ft Heavy Duty Super Winter Pool Cover is a solid, heavy-gauge winter cover built to protect inground pools from snow, ice and debris during the off-season.

This winter cover is engineered for durability and ease of use: a tightly woven 8 x 8 scrim polyethylene fabric weighing 2.36 oz/yd² with a five-foot overlap that simplifies installation and helps the cover sit freely on the water. The cover’s top is imperial blue and the underside is black, and it includes perimeter loops for vinyl water weights (sold separately). Backed by Robelle’s long experience and a ten-year warranty, this cover is intended for seasonal pool protection rather than in-season debris control.

How does this cover stand up to winter weather?

The Robelle Super Winter cover uses a heavy-duty polyethylene weave with a high scrim count to resist tearing and extension under weight. Its solid construction prevents water passage through the fabric, keeping the pool surface isolated from falling leaves and fine particles. The black underside also helps reduce light penetration, discouraging algae growth beneath the cover.

• 8 x 8 scrim for reinforced tensile strength
• 2.36 oz./yd² material weight—18% heavier than many standards
• Solid (non-permeable) design to block debris and light
• Black underside reduces sunlight and inhibits algae formation

What installation method is recommended and why?

Robelle specifies using vinyl water weights threaded through the cover’s perimeter loops as the exclusive installation method. Water weights let the cover float gently on the water surface without causing stress at anchor points, and they avoid deck damage that can occur with other fastening methods. Installers should avoid leaving excess material on the deck and tuck or pad exposed edges to prevent abrasion.

• Perimeter loops included for simple water-weight attachment
• Water weights sold separately—only they are recommended
• Five-foot overlap gives material to fold and secure without deck strain
• Pad exposed edges to protect against corners or abrasive surfaces

Will this cover fit pools with irregular shapes, steps or seats?

The cover is sold by pool size and already includes a five-foot overlap (the 25 x 45 ft cover yields a 30 x 50 ft overall piece), but pools with raised steps, benches, or other protrusions may need a larger size to ensure the cover floats loosely. If your pool has features that extend beyond the basin, choose the next size up to avoid excessive tension and ensure the cover can rest properly on the water.

• Includes 5' overlap—cover size becomes 30 x 50 ft with overlap
• Order larger if your pool has steps, seats, or protrusions
• Proper fit prevents undue stress and prolongs cover life
• Designed to float loosely rather than be taut across the surface

What maintenance and care should owners follow?

This cover is meant for the off-season; avoid using it as an in-season debris cover. Remove accumulated water and heavy snow periodically to relieve weight, and store the cover dry and folded when not in use. Inspect the loops and fabric for wear at the start and end of each season to keep the cover performing through its warranty period.

• Designed only for winter/off-season protection, not daily swimming use
• Clear heavy snow and standing water as needed to reduce stress
• Fold and store dry to prevent mildew or degradation
• Check loops and fabric for damage before each installation

Who is this for: Pool owners with inground pools up to 25 x 45 ft who want a rugged, solid winter cover that’s built to last. It’s a smart choice for anyone prioritizing longevity, a secure floating installation using water weights, and reduced light penetration to limit wintertime algae risk. If your pool has built-in steps or irregular features, consider ordering the next size up to ensure a loose, non-stressed fit. The Robelle Super Winter cover brings decades of design experience and a ten-year warranty for season-to-season reliability.
