Tremco #1 White Aggregate Marble:

Tremco #1 White Marble Roofing Aggregate

A Highly Reflective Aggregate for use in the Tremco Rock-It™ Roof Surfacing System

Tremco #1 White Marble Roofing Aggregate is used in conjunction with our Rock-It Adhesive to provide a highly reflective, high emissivity roof surfacing system for use with both cold and hot applied built-up (BUR) and modified bitumen (MB) roof systems.  The combination of white aggregate and white Rock-It Adhesive can help lower energy use, reduce the strain on a building's HVAC system and have a positive impact on the Urban Heat Island Effect.

Tremco #1 White Marble Roofing Aggregate is suitable for use on both new bituminous roof systems or as a restoration surfacing on existing roofs that are in good condition.  Tremco #1 White Marble Roofing Aggregate may also be applied to BUR and MB roof surfaces using other types of bituminous adhesives or flood coat applications of hot asphalt.


Durable Tremco #1 White Marble Roofing Aggregate is composed of specified gradations of marble aggregate with a maximum size of 3/8".
