Tapered polyiso - is an energy efficient roofing insulation designed to minimize heating and cooling costs while promoting positive rooftop drainage for most commercial roofs. Tapered polyiso minimizes the negative effects of ponding water, and reduces water infiltration. Applying tapered polyiso will help increase the service life of a roofing system.
Expanded polystyrene (EPS) - is a high performance roof insulation that promotes positive rooftop drainage, provides superior dimensional stability, and compressive strength. EPS is water resistant and can be applied to virtually any commercial or industrial roof system. By directing water to drains and scuppers, EPS can eliminate ponding water, and reduce water infiltration, lengthening the service life of a roof system.
