Ansgery Greenhouse Cover 16x20 ft - 16 mil Clear Heavy-Duty UV-Resistant Waterproof

Ansgery 16 Mil Greenhouse Cover is a heavy-duty, crystal-clear polyethylene tarp designed to protect and insulate garden structures while letting maximum daylight through.

This 16x20 ft tarp combines a three-layer woven and double-coated polyethylene construction with UV-resistant clarity and reinforced edges to deliver a long-lasting greenhouse panel or outdoor shelter cover. It’s engineered to pass light evenly, shed water, and resist tearing so you can use it for greenhouses, hoop houses, patio roofs, temporary repair patches, camping shelters, and other outdoor projects that need weather protection without sacrificing sunlight.

How does this tarp keep sunlight in while blocking the weather?

The Ansgery cover is made from clear, double-coated polyethylene that transmits high levels of natural light while providing a waterproof barrier. Its material balances transparency with weather resistance so plants receive light and structures stay dry.

• 16 mil thickness for rigidity and longer service life
• Three-layer woven core with double coating for tear resistance
• UV-stabilized formula to reduce sun damage and yellowing
• Clear finish to allow even light distribution inside the structure

What makes the edges and mounting points strong enough for outdoor use?

Edges are folded and reinforced, then fitted with rustproof grommets placed every 18 inches to create reliable attachment points. The tarp’s perimeter is further reinforced with woven backing to resist rips at stress points and extend the usable life of the cover.

• Double-sewn or heat-folded hems to limit fraying
• Rust-proof metal grommets at 18-inch intervals for secure fastening
• Reinforced corners to withstand tension and wind loads
• Recommended tie patterns explained for stronger hold in high winds

How easy is it to install and size for my frame?

The tarp ships at its stated dimensions (16 ft x 20 ft), so plan for a few extra inches when measuring your frame to ensure full coverage and overlap. Grommet spacing and the material’s manageable weight make it straightforward to position and secure with rope, bungee cords, or clamps.

• Actual size marked on product — choose slightly larger than your frame
• Grommets every 18 inches for flexible attachment layouts
• Lightweight enough for two people to handle while still durable
• Can be trimmed if a custom shape or smaller fit is required

Will this tarp work year-round in varying temperatures?

The polyethylene construction is designed to perform in both hot and cold conditions: it resists UV degradation in summer and helps shelter against chill and light freeze by retaining heat near the covered structure. While robust, fastening technique and wind exposure affect longevity—use recommended tie-downs in severe weather.

• UV-resistant coating limits heat-related breakdown
• Clear material allows passive solar warming in cooler months
• Waterproof surface prevents rain and snow penetration
• Use stronger fastening in windy or storm-prone locations

Who this is for: the Ansgery 16 Mil Greenhouse Cover suits gardeners, landscapers, hobby farmers, contractors, and DIY homeowners who need a transparent, heavy-duty protective sheet for greenhouses, temporary shelters, or repair projects. It’s a practical choice if you want a durable, high-transmission cover that balances weather protection with light availability, and can be trimmed or secured to fit frames, arbors, or makeshift roofs.
