Abstract
A single ply membrane roofing system includes a roofing insulation board which, preferably, is at least 45% by dry weight expanded perlite. One major surface of the insulation board is coated with a latex coating comprising, by dry weight, between 48.3% and 96% clay; between 3.1% and 33.3% latex; and between 0% and 34% sodium silicate. A single ply roofing membrane is adhered to the coated major surface of the insulation board with a roofing contact adhesive.
