Value Brand 15 x 20 ft 20 Mil Cotton Canvas Tarp Green

Standard-Duty Canvas Tarp

This green cotton canvas tarp is built for general-purpose coverage where heavy industrial strength is not required. It suits homeowners, gardeners and light commercial users needing a breathable, mildew-resistant barrier for equipment, firewood or temporary shelter. The standard-duty rating indicates it handles everyday exposure rather than sustained severe weather or abrasion.

Finished Dimensions and Grommet Spacing

The cut size is 15 x 20 ft, but the finished dimensions measure 14 ft 6 in by 19 ft 6 in after hemming, so coverage area is smaller than the nominal label. Nickel-plated brass grommets are placed every 24 in along the perimeter, which limits tie-down density for high-wind security. The double-stitched seams add edge strength, yet the 10 oz/sq yd fabric weight and 20 mil thickness set a ceiling on tear resistance under point loads.

Water Resistance and Breathability Trade-Off

The canvas is water resistant, not waterproof, so prolonged rain or pooling water will eventually penetrate the weave. Because the material is not breathable, condensation can form underneath when covering warm or moist objects, which may promote mildew despite the resistant treatment. The CPAI-63 standard confirms a level of flame retardancy, but the tarp offers no insulation or high-visibility features for specialised safety needs.
