Planitherm Ultra N is an advanced performance low-E (emissivity) glass with superior thermal insulation properties.
It’s manufactured on Saint-Gobain UK’s magnetron coater. A unique combination of multiple metal oxide layers are applied to high quality Planilux clear float glass using a magnetically enhanced cathodic sputtering process under vaccum condition. The resultant microscopically thin and transparent metallic coating very effectively reflects long-wave heat radiation back into a room, thereby retaining heat within a building, whilst maximizing light transmission.
