Residential Series ThermalHeart+® sliding windows use the sliding door system. The sill track has a flushline appearance. Interlocker stiles are flush in the closed position. An over-light transom allows over-lights in association with sliding panels. An under-light transom allows fixed glazing below opening panels, useful if requiring large openings but protecting against falls from a height. A vertical sliding window system is not offered.

For best overall performance, pair with The AGP System® with Solux-E® or Solux Ultra® low-e glass.
