Full Product Description
Our 38mm knotted polyethylene mesh is the preferred specification for smaller game bird enclosures and professional aviary installations where a finer mesh than the standard 50mm pheasant netting is required. At 38mm, the mesh is suited to partridge, quail, smaller pheasant poults, and the wide range of aviary species that require a closer mesh spacing to prevent escape, reduce entanglement risk, and exclude smaller predators.
Manufactured in our Fleetwood factory from high tenacity polyethylene in a traditional knotted construction. The knotting process — using a single English knot at each mesh intersection — produces a net that is significantly stronger and more dimensionally stable than woven or extruded alternatives of the same mesh size. The knot holds the mesh geometry firmly under load and impact, which matters on game enclosures where birds put constant physical pressure on the net face.
All netting is UV stabilised as standard, rot-proof, chemically inert, and colour-fast throughout its service life outdoors.

Applications
Partridge and Game Bird Release Pens — the 38mm mesh is well suited to partridge release pens where the smaller bird size and higher net activity makes a finer mesh preferable to the standard 50mm pheasant specification. The knotted construction resists the sustained pressure birds place on the net face at the perimeter.
Poult and Juvenile Pheasant Enclosures — where young pheasant poults are being held prior to release, a 38mm mesh reduces the risk of smaller birds pushing through or becoming entangled at the mesh boundary.
Flight Aviaries — for mixed species and smaller bird aviaries where a 50mm mesh opening is too large for the species being contained. The knotted PE construction is widely used by professional aviculturists and zoological collections for perimeter and overhead netting.
Hawk and Falcon Hack Pens — used in bird of prey conservation and falconry for hack pens and mews enclosures where mesh integrity and predator exclusion are both important. The heavier knotted construction withstands impacts from larger raptors more reliably than extruded or woven alternatives.
Poultry Runs and Free-Range Areas — overhead and perimeter netting for free-range poultry keeping at commercial and smallholder scale, providing aerial predator exclusion without the weight or cost of wire mesh.
Rabbit and Vermin Exclusion — used as an overhead net over vegetable gardens, soft fruit areas, and crop enclosures where a closer mesh than 50mm is required to exclude rabbits, pigeons, and other species.
Aquaculture Predator Exclusion — suitable for bird exclusion nets over freshwater pens and smaller aquaculture enclosures where the 38mm mesh provides effective deterrent coverage against herons, cormorants, and other species.

Buying direct from the manufacture
Boris Nets has been manufacturing netting in Fleetwood since 1958. Every metre of our knotted polyethylene range is produced in our own factory — you are buying from the manufacturer, not a distributor or reseller. This means competitive direct pricing, access to non-standard widths and lengths made to your specification, and consistent material quality backed by 65+ years of manufacturing experience. Contact us on 01253 874891 or email sales@borisnets.co.uk with your dimensions.
Why Knotted Construction Matters
There are three ways to manufacture a polyethylene net: knotted, woven (Raschel), and extruded. Woven and extruded processes are faster and cheaper, but the mesh is not dimensionally fixed — mesh openings can deform under load, particularly in diamond mesh configurations where the net stretches diagonally. A knotted net has a fixed intersection at every mesh junction, meaning the mesh size remains consistent under pressure, the net holds its shape on the frame, and load is distributed through the knot rather than relying on the mesh geometry alone. For any enclosure holding live animals or excluding active predators, knotted is the appropriate specification.
