CEMENTITIOUS BOARD INSULATION
 
** NOTE TO SPECIFIER ** LIGHTGUARD provides insulation as well as ballast. It is used as the ballast component of a Protected Membrane Roof (PMR) assembly and is suited for new or reroofing use on commercial and industrial buildings. LIGHTGUARD consists of a concrete panel laminated to insulation board. The panels can be installed on top of most types and brands of roof membranes, offering protection from thermal shock, weathering forces and maintenance related foot traffic. LIGHTGUARD and HEAVYGUARD, as part of a PMR, are effective in controlling condensation and dew point location in industrial plants such as paper mills. By insulating the roof assembly and keeping dew point above roof membrane, LIGHTGUARD protects valuable machinery in pulp and paper mills, textile mills and other installations where moisture can cause damage to equipment. LIGHTGUARD is reusable in reroofing and vertical expansion situations. It is free of chlorofluorocarbons (CFCs). HEAVYGUARD is a heavier version of the LIGHTGUARD panel. It is used where high traffic and higher point loading require a thicker concrete-panel component. Delete type not required.
