ADVANTAGES
* Low material and installation costs * Available in a wide range of sizes * Can be obtained in various densities * Easy to handle and apply * Simple to cut and shape with common tools * Excellent bond with drywall and non-solvent type adhesives * Clean, odorless, non-irritating to skin * Restricts moisture penetration		   CHARACTERISTICS
*Low thermal conductivity * Reflective white color * Effective over wide temperature range * High strength to weight ratio * Will not twist or warp * Unaffected by vibration * Non-dusting * Resistant to most acids and alkalis * Does not support bacterial growth
                                                     NO CFC'S
 *R* Means resistance to heat flow. The higher the *R* value, the greater the insulating power.
