Buying Guide
Key considerations for choosing an 18 ft round pool cover include material strength, wind resistance, UV protection, seam construction, and fit accuracy. Material options range from laminated polyethylene to Oxford fabric. Heavier fabrics tend to offer better tear resistance but may require more effort to install. Windproof features, such as multiple straps, tighten systems, and grommets, help keep covers in place during storms. A one-piece or seamless edge design reduces edge cracking over time. Always measure your pool diameter and check the product’s compatibility with your pool wall type (steel-wall vs. metal frame).
What should you prioritize when comparing products?
- Durability: Look for high scrim counts (12×12 or higher) and welded or heat-sealed seams.
- Wind resistance: Four-layer systems, multiple straps, and robust tightening devices deliver the strongest hold.
- UV and cold protection: LDPE coatings and dark undersides help with sunlight control and algae prevention.
- Fit and compatibility: Confirm your pool model and rim type to avoid oversized or undersized covers.
Maintenance tips: Remove debris before covering, avoid dragging covers across rough surfaces, and store in a dry place when not in use. Inspect straps and seams annually for signs of wear and replace components as needed to preserve performance.
Frequently Asked Questions
- What size is needed for an 18 ft round pool? Use an 18 ft round cover designed specifically for 18 ft round above-ground pools to ensure a proper fit.
- Can I use a standard tarp instead of a winter cover? A standard tarp often lacks reinforced seams, windproof features, and UV protection; it is not designed for long-term winter use on pools.
- How important are windproof features? Very important in windy climates; multiple straps, reinforced edges, and a secure tightening system help prevent cover displacement.
- Is a black underside better for algae prevention? A dark underside reduces sunlight reaching the water, which can help limit algae growth in covered periods.
- Do covers come with installation hardware? Some models include winches, cables, and straps; others may require purchasing hardware separately.
