What Do U-Value?
Vitro Architectural Glass provides high-performance glass options that significantly enhance U-value for superior thermal performance.
Sungate ThermL™ Glass
Vitro’s new U-value enhancing low-e coating enables superior thermal performance without changing the visual characteristics of the IGU because of its colorless and low-reflective aesthetic.
Sungate® 400 Passive Low‑e Glass
Sungate® 400 glass is a highly transparent, passive low-e glass designed specifically for use in heating-dominated climates.
VacuMax™ Vacuum Insulating Glass (VIG)
With R-values of R20, VacuMax™ VIG delivers thermal insulation performance that is 3-5 times better than conventional insulating glass and 20 times better than monolithic glass.
