Flame Spread <br />2. Smoke Deveoped 50 (fiberglass and phenolic) <br />150 (elastomeric) <br />Insulation on all cold surfaces where vapor barrier jackets <br />qre used will be applied with a continuous unbroken vapor <br />seal. Supports or anchors that are secured directly to cold <br />surfaces must be adequately insulated and vapor sealed to <br />prevent condensation. <br />Support inserts for all insulated piping shall be installed <br />at all outside hanger points. Inserts between the pipe and <br />pipe hangers shall consist of wood plugs or rigid insulation <br />sections of equal thickness of the pipe insulation. <br />Inserts shall be installed in a manner to completely <br />support the pipe and not crush the insulation or damage <br />the vapor barrier. <br />1. <br />Insulation exterior shall be cleanable grease-resistant, <br />non-flaking and non-peeling. Insulation shall conform to <br />the specified temperature ranges and densities in pounds <br />per cubic foot. Insulation for fittings, flanges and valves <br />shall be premolded, precut or job fabricated insulation of <br />the same thickness and conductivity as used on adjacent piping <br />1.03 RELATED WORK <br />A.
