Abstract
A wind lift mitigation net for mitigating or preventing wind lift of at least one membrane covering an outdoor aggregation of matter is provided. The wind lift mitigation net comprises a plurality of monofilaments. At least some of the monofilaments may each have a cross-sectional shape that comprises at least one vertex. The cross-sectional shape may, for example, be a non-circular shape such as a tear drop, triangular, square or stellate shape. At least some of the monofilaments may each have at least one substantially planar surface.
Claims17
A knitted wind lift mitigation net for mitigating or preventing wind lift of at least one membrane covering an outdoor aggregation of matter, the knitted wind lift mitigation net comprising:
- a plurality of monofilaments made from a plastics material, each monofilament having a length dimension, a width dimension and a depth dimension, wherein the length dimension is greater than the width and depth dimensions, wherein each of the width and depth dimensions is less than 1 millimetre, and wherein at least some of the monofilaments each have a cross-sectional shape that comprises at least one vertex;
- and
- wherein the knitted wind lift mitigation net has:
- an area density of 250 g/m 2 to 350 g/m2;
- a bending length of 70-80 mm;
- a flexural rigidity of 2000-4000pjoules/m;
- a mean peak width of 600-1000 μm;
- and
- a void volume of 840-1050 cm3/m2.

A method, comprising:
- covering an outdoor aggregation of matter with at least one membrane;
- at least partially covering the at least one membrane with a wind lift mitigation net comprising a plurality of monofilaments made from a plastics material, each monofilament having a length dimension, a width dimension and a depth dimension, wherein the length dimension is greater than the width and depth dimensions, wherein each of the width and depth dimensions is less than 1 millimetre, wherein at least some of the monofilaments each have a cross-sectional shape that comprises at least one vertex or at least one substantially planar surface;
- and
- wherein the wind lift mitigation net has:
- an area density of 250 g/m 2 to 350 g/m2;
- a bending length of 70-80 mm;
- a flexural rigidity of 2000-4000pjoules/m;
- a mean peak width of 600-1000 μm;
