Surpassing Performance Standards

EnviroSeal nXt

EnviroSeal nXt outperforms other single-seal and dual-seal spacers. Windows built with EnviroSeal nXt exhibit the lowest failure rates in the industry which is ideal with insulated glass units. Considered the glass spacer of the future, this warm-edge glass spacer is highly energy efficient. 

Designed without metal, the spacer conducts less thermal energy thus improving the edge of glass temperature by as much as 16.6° F when compared to other spacer systems. By regulating the thermal transfer, windows with EnviroSeal nXt technology will keep your home comfortable year round.
