This is the warp knitted shade cloth we run on greenhouse frames and open structures where the cover has to hold its shape against the wind. The warp knit locks the yarn into a dense, stable structure, so the cloth keeps its span under load instead of stretching and sagging the way a loose knit does. The same structure gives it windbreak duty on the exposed side of a house, cutting the wind that would otherwise flatten a young crop. Shade rate runs from 30 to 95 percent and the roll is cut to the frame you are covering, so one product suits a greenhouse roof and an open nursery structure.
A shade cloth on an open structure has two jobs at once: cut the sun load and stay put when the wind gets under it. A loose knit stretches and sags under that load. A warp knitted cloth is built the other way, with the yarn locked into the structure so the cover keeps its span.
Warp knitting builds the cloth from yarns running lengthwise that interlock at every course, which gives a dense and dimensionally stable structure rather than a mesh that pulls out of shape. On a greenhouse frame that matters through a season of wind, because the cloth keeps the span it was cut to instead of stretching between the fixings and hanging loose. The dense structure also blocks more of what the wind carries, which is why the same cloth doubles as a windbreak on the exposed side of a house.
The cloth goes over greenhouse roofs and arched frames, across nursery structures and along the windward side of a house where the wind would otherwise flatten young plants. Growers running pots and trays under the same cover often pair it with a planting bag, and the wider shade net range covers the reflective and coloured types where the job calls for something other than a plain knitted cloth. Because the structure is stable, a single span can be run across a wide house without extra support between the fixings.

Shade rate is the first number to settle because it decides how much sun the crop keeps. We make this cloth anywhere from 30 to 95 percent, so a vegetable house that needs the sun load cut hard runs at the heavy end and a nursery structure that only wants light shading runs lighter. Span is the second choice, and because the warp knit holds its shape the cloth covers a wide house without extra support between fixings. A knitted monofilament net covers the same idea where a finer weave is wanted, while this cloth covers the standard greenhouse and structure job.
Width, length, shade percentage and colour are all made to order, so the first detail to confirm is the span of the house or the structure you are covering. Rolls ship in export packing and are cut to suit the frame. Growers tracking how shade cloth performs across a season can follow trade coverage such as HortiDaily and FreshPlaza for what is being installed on commercial sites.
How is a warp knitted cloth different from a standard knitted net?
The yarns run lengthwise and interlock at every course, so the cloth is dense and keeps its shape under wind load rather than stretching between the fixings.
Can the same cloth serve as a windbreak?
Yes. The dense structure blocks wind as well as sun, so it is commonly run along the windward side of a house as well as over the roof.
What shade percentage should I order?
A vegetable house that needs the sun load cut hard runs at the heavy end of the 30 to 95 percent range. A nursery structure that only wants light shading runs lighter. Tell us the crop and the site and we will advise.
Tell us the span, the shade percentage and the colour you are working to, and we will confirm the width and the packing that suit your order.
