    Perforated

    Solid

    Prongs sink into rigid insulation and hold the washer in place, so it won't shift during installation.
    Perforated—These economical washers are best for interior applications.
    Solid—When fastened, these washers flex to create a seal around the connection that blocks out air and moisture. They are most often used on exterior walls to attach weather barriers over insulation.
