The best shade cloth under $50

The best-documented shade fabric at any price on this site, and it sits comfortably inside this band.

A fifteen-year fabric warranty against cracks, splits and tears due to UV degradation. Read what that is written against: not a general "15-year product", but the specific failure mode that ends a shade cloth's life. Knitted polyethylene does not wear out mechanically — it goes brittle under ultraviolet light and then splits at a fold or a fixing. A warranty naming that is a manufacturer betting on its own polymer, and nothing else in this band has one.

Knitted HDPE in a mono/mono construction, up to 50% UV block, breathable to air and water. Mono/mono means monofilament in both directions, which is the knit that resists running when a thread is cut — the thing that turns a small nick into a ladder across the cloth.

6 x 15 ft, 6 x 100 ft and 12 x 50 ft. The 12 ft width is the one worth knowing about: it spans a 10 to 12 ft bay in a single piece, and a cloth seamed down the middle fails at the seam.

50% is the density most vegetables want, which is why this is sold as a garden cover — enough to stop scorch without starving the plants of light. For shading people rather than plants the 70% below is the better density, and Coolaroo's 90% fabric is better still.

The cons: breathable means it blocks no rain at all, and it arrives as cloth. No grommets, no hem, no fixings. Edge tape or a batten is a separate purchase and it is not optional — a knitted edge loaded at one point will run.

The lightest density Coolaroo publishes, and the right answer to a narrower problem than most people think they have.

Knitted HDPE at 30% UV block. Thirty per cent barely reads as shade standing under it — and that is the point. It takes the edge off peak afternoon sun on crops that want full light the rest of the day, which is a real horticultural requirement rather than a compromise.

Where it earns its place: leafy salads and seedlings that bolt or scorch in a heatwave but stop producing under heavy shade. Over a seating area it will do essentially nothing you can feel.

6 x 15 ft only, which is the narrowest size offering in the band — worth checking against the bed or frame you are covering before you order.

And the gap worth naming: no warranty term is published for this density. Same brand, same knitted HDPE, and the fifteen-year UV warranty that comes with the 50% and the 90% fabric is not published here. If the warranty is part of why you are buying Coolaroo, this is not the density to buy.

The least expensive fabric in the band and simultaneously the densest, which makes it the straightforward recommendation for most uses.

Knitted HDPE at up to 70% UV block, breathable. Seventy per cent is the density that matches what most greenhouse and screening guidance actually asks for, and it is enough to make a patio or a pergola genuinely comfortable rather than merely patterned.

6 x 15 ft, 6 x 50 ft, 6 x 100 ft and 12 x 50 ft — the full set of Coolaroo widths, including the 12 ft roll that covers a bay in one piece.

It is sold as screening rather than as a garden cover, and that is a useful hint about the second job it does. At 70% it works vertically as well as overhead: a fence panel or a privacy screen on a boundary, where the breathable knit lets wind through instead of turning the fence into a sail.

The published gap, and it is the same one as the 30% cloth: no warranty term. Coolaroo publishes its fifteen-year UV warranty on the 50% Garden Cover and the 90% Sun Protection fabric and not on the Screening range. Cheapest in the band, denser cloth, no document — that is the trade, stated plainly.
