SUBJECT: THE ADVANTAGES OF FIBER GLASS IN WET-JET AND SILVERLEAF OVER ASBESTOS IN COMPETITIVE COATINGS.
FIBER GLASS PREVENTS "WICKING" OF MOISTURE UNDERNEATH COATING! This means that these PACE PRODUCTS made with FIBER GLASS will last much longer than ordinary coatings using asbestos fiber. Moisture is the deadly enemy of roof life. It becomes dangerous when it gets underneath the roof mat. As long as the coating and roof mat offer a solid barrier resistant to penetration, there is no problem. When a break develops, even an opening the size of a pin prick, moisture creeps in. Roof protection begins to break down. Asbestos is tubular in construction. It provides easy access for water to funnel down through the strands. This is a gradual process. It takes months to complete the process of drawing moisture underneath the film of coating. This action of asbestos can be compared to the wick in an old-fashioned oil lamp. Once asbestos starts wicking water under the film of coating, roof protection is lost. Breaks in the coating and roof mat occur causing leaks. Heat from the sun turns the trapped moisture into steam which in turn forms blisters which further weaken the roof mat. This cycle of deterioration cannot occur with PACE PRODUCTS made with Fiber Glass. Fiber Glass is not tubular. It cannot absorb moisture. It cannot funnel or carry water through and under the roof coating. Fiber Glass is a relatively new development in the Protective coating field. Its value cannot be over-emphasized as a means of providing extra years of life expectancy. In SILVERLEAF, one more important and definite advantage with Fiber Glass is "non-browning". Since Fiber Glass does not wick moisture, it also does not act as a wick or carrier for asphalt. Many aluminum coatings, using asbestos fibers, brown-out a few months after application. Tubular asbestos is the culprit. It brings up the brownish asphalt through the aluminum pigment. Fiber Glass in SILVERLEAF prevents this!
