Standards Testing by independent laboratories verifies the superior advantages of ASTEC Re-Ply membrane roofing upgrades when applied professionally and systematically to various base roof materials. Additional advantages of a seamless monolithic, ceramic insulating, cool-roof conversion include: maximizing heat reflectivity and emissivity, wind resistance, and fire resistance, while minimizing utility costs, insurance costs, thermal shock shift, fungal and corrosive degradation, and attendant facility maintenance. These advantages allow a written 10-Year Renewable Warranty on all ASTEC Re-Ply Roofing Systems.

Tested by TRW: "Your (membrane) absorbs up to 50% less solar energy than normal (coatings)".
Tested by Christian Testing Labs: "ICC's ASTEC ceramic coating significantly outperformed R-20,four inches of foam insulation in heat gain tests."
Tested by U.S. Dept. of the Air Force: "Reduced interior building temperature by 17 degrees..." "The coating is unquestionably an effective and cost effective way to insulate buildings and still maintain an attractive appearance."

Note: Wet adhesion testing was completed using Insulating Coatings Primer B 16 applied to the galvanized metal, allowed to dry, and then the ASTEC #2000 Finish coat applied to the primed galvanized metal. This is the only test that included the use of a primer with the (ASTEC Re-Ply #2000 Finish) coating.
