Residential ThermalHEART Sliding windows use the sliding door system except for a narrower rail at top and bottom. A smaller inter-locker mullion is also generally used. The sill track has a flush-line appearance.
Inter-locker stiles are flush in the closed position. An over-light transom allows over-lights in association with sliding panels. A vertical sliding window system is not offered.
