How it Works? VacStar system rests on frame or wall with no additional loading on glass VacStar system attached to existing widow glass with warm edge, creating a sealed air cavity. • Triple insulted glass system is created to drastically improve glass performance • New VacStar system sealed permanently • *Reduce solar heat gain by~70% and colling energy load by as much as 30% for typical single glass window (tined or solar reflective) in commercial buildings • *Payback time of BVG retrofit solution is less than 5 years.
