Our Lift Out Secondary Glazing units offer an alternative to horizontal and vertical sliders, and are able to treat large areas of clear glass while avoiding being visible from outside. The large panels can be lifted out of the frame for cleaning or to provide ventilation. However it is not an ideal system, for where regular access is required.
Lift Out Units are available in our Economy Odd Leg and Luxury Subframe systems. Units can be coupled together where required and combination units can be created to include hinged and lift out panels. These features allow complicated window styles, such as a top lite over a fixed, or hard to treat areas in tight spaces, such as bay windows or large fixed windows to be effectively treated.
