Buying Mesh Wire Mesh wire can be used in homes as a way to extend available space for storing items, protecting the home from insects and bugs or as an insert for cabinet doors. When purchasing mesh wire, it is important to consider how the wire screen will be used. Applications There are numerous different ways in which mesh wire can be used through a home. The way in which it is used will determine the type of metal mesh that should be purchased and how fine the mesh should be. Screens Â¨C Screens in the home include window screens, fireplace screens, and insect or animal screens. Window screens that are intended to keep out small insects rarely need to be overwhelmingly strong, but need to have a fine mesh that will not allow flies or other insects to fly into the house. Screens that are intended to keep out animals do not need to be extremely finely meshed, but should have mesh openings that are small enough to prevent the intended animal from entering the home (mice, raccoons, voles, and such). Cabinet Screens Â¨C Wire mesh that is installed in cabinet panels is often utilized to allow ventilation inside the cabinets. Mesh for this application should be fine enough to prevent small animals like mice from entering the storage area. Resources It is possible to purchase mesh wire from most large home improvement centers. There are also numerous online sources from which to order mesh in both specific lengths and sizes or in rolls.
