High Performance Windows

Wausau Window and Wall Systems' INvent™ Series high-performance, fixed and operable windows are manufactured using recycled aluminum and allow daylighting and outside views. Optional, between glass blinds enhance occupants' control, while lowering maintenance. Operable windows present a seasonal opportunity for natural ventilation. Wausau's INvent Series 2250i-XLT fixed windows use triple insulating glass and an extra-wide thermal barrier to achieve NFRC U-factors as low as 0.19. Learn more>
