Glacier White Paver

Meeting Reflectance and Emittance Requirements

In addition to Hanover´s Glacier White Paver satisfying the reflectance and emittance requirements of both ASTM C 1549 and ASTM C 1371, respectfully, Hanover® has now completed test data of its Glacier White under the ASTM E 903 for reflectance and E 408 for emittance. Hanover´s Glacier White paver surpassed the minimum requirements for solar reflectance of .65 and also passed the .90 requirement for emittance under the test protocol.

We have also recently completed the first leg of the initial testing certification by the Cool Roof Rating Council and have had Glacier White pavers tested by the certified independent laboratory for submission to Cool Roof Rating Council for review. Along with the Cool Roof Rating Council´s initial review, our paver samples have been placed into their farm site for three year aged weathering values. Those pavers will be periodically tested to compare changes or differences in its reflectance or emittance as it is exposed to environmental conditions.

Hanover´s Glacier White paver can become an integral part of achieving LEED value credits under LEED NC Version 2.1 Credit 7.2, which provides one point under Heat Island Effect Roof for compliance with ASTM E 408 with a value of .9 or greater. This provides the ability for the use of the Hanover® Glacier White paver to provide the full one credit value in conjunction with this LEEDS version. Hanover® Glacier White pavers can be used for plaza or roof applications requiring LEED certification in either pedestal configurations and/or loose-laid applications.
