Each replacement window series is engineered for greater strength in material and components over the many available options on the market in its respective class. The structural framing of each series offers durability both to the element and everyday operation. The actual internal chamber design allows for better energy retention while increasing strength.
The Light-LiftTm SP window sash balance system offers one of the best silent and smooth movement of the sashes to glide up and down with ease.
In addition to having a low profile that complements the window, the hardware is tailored for longevity and ease of use. So, the lock-and-tilt latches continue to function well year after year.
