Nippon Sheet Glass Co. has developed the world's first commercialized vacuum glazing product known as SPACIA. The glazing consists of two 3-mm thick glass with 0.2 mm vacuum spacing gap, giving a total thickness of 6 mm. Due to the vacuum space, SPACIA's heat transfer is extremely reduced to the level of a guarter of 3mm thick single pane's and a half of 12mm thick double glazing's.
Its thin structure enables to replace a single pane with SPACIA without changing an existing framing sash in old houses.
SPACIA can reduce the air conditioning energy load by 31% as compared a single pane, when used in wooden houses.
SPACIA is being produced and supplied by Nippon Sheet Glass Spacia Co.,LTD. |
