Buying Guide: Key Purchase Considerations
- Scrim count: Higher scrim (for example 8 x 8 or 10 x 10) indicates greater fabric density and resistance to tearing. Compare scrim counts across models to predict durability.
- Overlap: A larger overlap (5 ft or more) helps prevent wind from lifting the cover and provides extra material for a snug fit over irregular corners or coping.
- Material weight: Heavier covers (measured in oz/yd²) generally offer stronger protection but can be heavier to handle. Balance weight with ease of installation in your climate.
- Seams and seals: Heat-sealed seams reduce leakage and debris entry. Look for covers that advertise sealed or heat-sealed seams for winter durability.
- UV resistance: Year-round sun exposure can degrade covers and pool finishes. UV-rated materials help prolong cover life and protect pool interiors during summer.
- Warranty: A longer warranty signals confidence in performance and service life. Consider brands offering 8–12 year warranties for cost-effective protection.
- Overlap fit and size accuracy: Confirm the overlap aligns with your pool’s coping and surrounding structure. A 4–5 foot overlap is common and generally sufficient for secure coverage.
- Installation ease: Some covers include installation aids such as water tubes sleeves or included tie-down options. If you prefer simpler setup, prioritize these features.
- Warranty coverage nuances: Review what the warranty covers (material failures, tears, seam failures) and any exclusions related to improper installation or material misuse.
- Climate compatibility: In areas with extreme cold or heavy snowfall, prioritize heavier-duty covers with robust scrim and sealing capabilities to minimize maintenance.
