Ansgery Clear Greenhouse Cover 12x20 ft — 16 mil Heavy-Duty UV‑Resistant, Waterproof with Reinforced Hems & Grommets

Ansgery 16 mil clear greenhouse cover is a heavy-duty, UV-resistant polyethylene tarp that protects structures while maximizing light transmission.

This transparent 12x20 ft tarp combines a woven core with a double-coated polyethylene finish to deliver a tear-resistant, waterproof sheet designed for greenhouses, canopies, and repair work. At 16 mil thickness it balances durability with flexibility, letting natural sunlight through for even warmth while resisting UV degradation and moisture. Built-in reinforced hems and rust-proof grommets make fastening and long-term installation easier, and the clear material keeps the interior bright without extra shading.

How well does this cover let sunlight through without sacrificing protection?

The Ansgery clear tarp is designed to allow high light transmission so plants or interior spaces receive ample daylight while the material still blocks harmful UV deterioration. Its three-layer construction (woven core and double-coated surfaces) keeps the sheet strong and weather-resistant without becoming opaque.

• High transparency for natural light and even temperature distribution.
• UV-resistant coating to reduce material breakdown from sunlight.
• 16 mil thickness provides a balance of light passage and durability.

Is it strong enough to handle wind, rain, and repeated use?

The tarp features reinforced hems and double-folded edges with rope, plus rust-proof grommets placed approximately every 18 inches to improve stability and attachment points. These reinforcements increase tear resistance and make the sheet suitable for semi-permanent installations and frequent deployments.

• Double-reinforced corners and folded edges for better tear resistance.
• Rust-proof grommets at denser spacing for easier, firmer ties.
• Woven inner layer adds tensile strength under tension and wind load.

How do I install and secure the 12x20 ft greenhouse tarp correctly?

Installation is straightforward: lay the tarp over the frame, align the cover so it extends a few inches past the structure, then secure through the grommets using rope, bungee cords, or straps. Because fastening method matters in strong winds, use tight, evenly spaced ties and consider wind braces or extra anchors for exposed sites.

• Order a tarp a few inches larger than your frame for full coverage.
• Use the grommets every 18 inches for consistent tie points and reduced stress.
• In high winds, add extra anchors, straps, or reinforce the corners to prevent grommet failure.

What practical uses does this clear plastic tarp serve beyond greenhouses?

While ideal as a greenhouse cover, this waterproof Ansgery tarp is versatile for repair, construction, camping, and temporary shelter applications. It provides protection from wind and rain, functions as a roof shade, and can act as a clear barrier to retain warmth during cooler months while keeping visibility.

• Temporary roof or canopy cover for construction and repairs.
• Camping shelter, windbreak, or rainproof groundsheet with light transmission.
• Landscape or agricultural cover to protect plants while maintaining sunlight.

Who is this for: The Ansgery 16 mil clear greenhouse cover suits hobby growers, small commercial growers, landscapers, contractors, and homeowners who need a strong, transparent waterproof tarp. Choose this 12x20 ft size when you want a balance of coverage and manageability, and select a slightly larger tarp than your frame to ensure complete protection. If you expect severe winds, plan additional anchoring and check fastenings regularly to prolong the tarp’s service life.
