"an effective mesh that provides a discreet and impenetrable barrier that protects the premises without harming the birds"

The use of the Birdnet system is one of the most effective and long lasting ways of proofing buildings and other structures against all urban bird species. The system consists of a 2mm stainless steel perimeter straining cable, which is supported normally by stainless steel fixings drilled into the structure at regular centres. The cable is tensioned using a high quality grade 316 stainless steel M5 or M6 barrel strainer and the net securely attached to it by stainless steel hog rings.

Heavy-duty M6 and M8 stainless steel netbolts are used in the corners or where points of abnormal stress occur. Intermediate fixings generally consist of 50mm stainless steel split pins inserted into 50mm nylon anchor rivets, or a HiltiHA8 zinc plated metal hanger on larger netting systems. Where we are fixing into cladding systems we are able to use a 25mm x 25mm right-angled passivated bracket or a 40mm x 40mm plastic injection moulded base to avoid penetrating the surface material.

The Birdnet netting is constructed from high density ultra-violet stabilised knotted 12/6 polyethylene being chemically inert and rot proof in addition to offering a high resistance to a wide range of chemical and environmental conditions. The result is a high quality tensioned Birdnet sealing the perimeter area and preventing gaps appearing. Birdnet is available in four mesh sizes and various colours depending on the physical surroundings and particular species causing the problem.
