Sometimes, adhesives will not achieve the wind resistance necessary to satisfy Building Code requirements, in which case using fasteners is the better alternative. Furthermore, adhesives typi-callycostmorethanfasteners,adding anywhere from 25 to 40 per cent to the cost of a mechanically fastened system; in real dollars, this will be more than a cost increase to the electrical contract.
