| Woven Polyethylene Tarp | Woven polyethylene fabric with laminated coatings | High when seams and edges are intact | Low | Usually moderate to high, depending on coating | Covering hay, feed, machinery, pallets, and temporary storage areas | Use a raised or sloped cover so water can drain. Do not seal damp hay under a non-breathable tarp. |
| Heavy-Duty PVC-Coated Tarp | Polyester or polyethylene base with PVC coating | Very high when properly tensioned | Very low | High in products designed for outdoor exposure | Long-term equipment, trailer, building, and bulk-material protection | Heavier and less flexible than polyethylene. Secure it carefully to reduce wind loads. |
| Breathable Hay Tarp | Coated woven fabric with controlled vapor transmission | Moderate to high; varies by construction | Higher than solid plastic tarps | Often high, but product specifications should be checked | Round or square hay stored outdoors | Hay should be adequately dry before covering. Keep the tarp above the stack and allow drainage around the sides. |
| Mesh or Shade Tarp | Woven polyethylene, polypropylene, or coated mesh | Low to moderate, depending on mesh opening | High | Moderate to high when UV-stabilized | Shade structures, wind reduction, livestock shelters, and crop protection | It cannot provide the same rain protection as a solid tarp. Select shade percentage according to crop or animal needs. |
| Silage or Bunker Cover | Heavy polyethylene film or reinforced polyethylene fabric | Very high when overlapped and weighted correctly | Very low | Moderate to high, depending on intended storage period | Sealing silage piles, bunker silos, and forage storage | Use continuous coverage, adequate overlap, and approved weights. Inspect for punctures and repair them promptly. |
| Clear Greenhouse or Crop Cover | Clear polyethylene film or reinforced transparent sheet | High when installed with sealed or overlapped joints | Low; ventilation must be designed separately | UV-stabilized products generally last longer outdoors | Frost protection, temporary crop tunnels, and covered growing areas | Monitor heat and humidity. Transparent covers can raise internal temperatures quickly in direct sunlight. |
| Canvas or Cotton-Blend Tarp | Woven cotton, polyester, or blended fabric | Moderate to high when treated; not always fully waterproof | Higher than coated plastic, especially when untreated | Moderate; prolonged sun exposure can weaken natural fibers | Short-term equipment covers and work-area protection | Heavier when wet and may mildew if stored damp. It is not the first choice for long-term hay storage. |
| Insulated Livestock Tarp | Coated fabric with reflective or insulating layers | High on the exterior surface | Low to moderate, depending on design | Usually moderate to high | Temporary livestock windbreaks, shade areas, and weather shelters | Provide sufficient ventilation and avoid loose fabric that animals can chew, pull, or become entangled in. |
| Trailer or Truck Tarp | Coated polyester, PVC-coated fabric, or reinforced polyethylene | High when fitted and tensioned correctly | Low | Usually high for transportation use | Protecting grain, hay, soil, tools, and equipment during transport | Choose reinforced hems and strong attachment points. Check clearance, load stability, and local transport requirements. |
