The P-1 test is considered to be the world’s toughest durability test. All units are put in hot boxes and are continuously exposed to 140°F/60°C, 95-100% humidity and constant UV bombardment. Each week of testing is equivalent to one year of actual field use.
As you can see, Super Spacer sealed with hot-melt butyl far outperforms other single and dual seal spacing systems. EnviroSeal nXt™ units far surpass what is considered to be acceptable field performance standards. Windows built with EnviroSeal nXt™ exhibits the lowest failure rates in the industry – virtually zero.
