Mcalpine ARB-1 Anti Cross-Flow and Rodent Barrier Valve, Black

Product Information

Below, we have outlined the properties of some commonly employed meshes. These include mesh to prevent the passage of rodents (both rats and mice), insects (including specifically midges) and for use in beekeeping applications. Of note, much of the information below has been advised to us by the British Pest Control Association (BPCA). Rodent Mesh (rats and mice) Gaps or flaws along building exteriors where the wall framing or siding meets the foundation provide easy entry for rodents. Such openings can be pre-vented by well-formed and finished concrete work and installation of tight wall framing and siding, or installing metal screed-type flashing between the siding and the foundation. Use of rodent-proof exterior surface materials such as concrete, plaster, or metal sheeting is also effective if properly installed so that all ribs or corrugations are closed.

We provide a variety of effective proofing solutions against rodent infestations to help protect every aspect of your business: The choice between concrete and wire mesh depends on the expected life of the structure. Though wire mesh costs considerably less than concrete, its usefulness generally lasts only 5 to 10 years. Flexi Armour Ground Mesh - is a highly corrosion resistant, flexible and sturdy ground covering mesh that discreetly prevents burrowing pests like rats from creating underground dens and safe harbourages close to your facilities, by proofing the ground around the property to prevent tunnel excavation and damage.There are many points of potential entry into a building for a rodent. One of the reasons businesses develop pest problems is because they don’t fully rodent-proof their premises’. Proofing is always the first line of defense against rodent infestations. The Flexi Armour rodent proofing range of door seals provides effective proofing measures, to help prevent the entry of rats and mice and reduce the risk of a rodent infestation developing on your premises. As the valves are one way, they do not stop anything from exiting the pipes in the usual way. After your sewage has freely left the pipe, the valve closes up again automatically. All vents and duct openings for heating and air conditioning should be screened or raised and/or guarded with an excluder device to prevent rodent entry. Residential cold air return grills can easily be mouse-proofed by placing 1/4-inch (0.6-cm) hardware cloth behind the grill where it is not unsightly. In some applications, power vents can be covered with hinged metal plates (louvered) that open with air flow and close when fans are off. These louvers are only effective if they fit tightly and the sides are recessed to prevent rodents from pushing through them. Caution: Hardware cloth less than 1/2 x 1/2 inch (1.3 x 1.3 cm) significantly reduces air flow. In buildings where ventilation is already marginally adequate or inadequate, such further restrictions may be unacceptable. In some locations, small mesh screens can become clogged with dust or freeze over. In such situations, the use of 1/2 x 1/2-inch (1.3 x 1.3-cm) hardware cloth is a reasonable compromise between ventilation requirements and rodent control. Standard insect mesh (aka fly mesh or flymesh) has a hole size of 1.36 mm x 1.36 mm. This is small enough to stop the vast majority of unwanted insects, including flies, mosquitoes, wasps and bees. Insect mesh is available to buy in our online shop insect mesh category. Soffit Vent Mesh Rodent Barrier– the combination of knitted stainless steel mesh and our unique resilient epoxy resin provides a flexible yet sturdy barrier to prevent rodents chewing through to exploit expansion gaps.

Figure 15. Left: A curtain wall made of concrete will prevent rats from burrowing under foundations to gain entry to buildings. Curtain walls can be installed on existing buildings. A horizontal footing extension often deflects burrowing rodents away from structures. Right: Feed sheds, corn cribs, and other existing wooden structures can be rodent-proofed by installing hardware cloth topped by a band of sheet metal. The hardware cloth can also serve as a curtain wall to prevent rodent burrowing. The valves do not require any maintenance as they are made using 316L grade stainless steel, and once fitted you can rest assured it will do its job for up to 20 or more years. Flexi ArmourBuilding Seal Mesh - is a highly corrosive resistant, flexible, galvanised stainless steel knitted mesh which can be swiftly installed around the perimeter of cladded buildings as an impenetrable barrier to rodents.Rats typically burrow and nest under feed bunks that are placed directly on the ground or near ground level. Properly designed concrete bunks that sit tightly on a concrete base eliminate rodent habitat. Though cattle traffic may discourage burrowing under the concrete slab, a foundation may be needed to prevent burrowing around the sides of the slab that do not receive heavy cattle use. Concrete slabs on which feed bins are placed should have foundations extending 36 inches (91 cm) into the soil at the outer edge to prevent rats from burrowing under the slab. Installing heavy gravel and maintaining a clean, weed-free zone around the perimeter of the slab will also discourage rat burrowing and permit easier detection of rat activity. Next working day delivery is not available for the Scottish Highlands and some remote areas where an additional charge may apply. Rodents often gnaw into wall materials at corners or where joints in construction materials provide an edge. Poor construction techniques may allow rodents to gain access through materials that are otherwise considered rodent-proof. When rats or mice are present in a building, attention must be given to interior as well as exterior rodent-proofing to remove all sources of shelter. A combination of actions is required in such instances, as no single effort is likely to yield the desired result.
