At the heart of C.U.in is suspended film technology — a transparent film placed between two panes of glass within a sealed IGU, creating a triple glazing effect. This film acts as an additional thermal barrier and is coated to reflect heat back into the room, similar to a third pane in a conventional triple-glazed unit.
Unlike gas-filled cavities alone, this approach creates a multi-layered thermal shield that reduces heat loss, blocks UV, and maintains clarity — all in a unit that’s slimmer and lighter than standard triple glazing.
