Low-E Glass allows you to be warmer in the winter and cooler in the summer – saving on heating and air conditioning along the way. Low-E Glass is a series of virtually invisible layers of metallic coating inside the sealed unit that increases the insulating value of a double-glazed window. Low-E will also reduce the harmful effects of UV rays on your interior fabrics and finishes by up to 55%.

Argon Gas is a completely safe, naturally inert gas that can be pumped into the air space of the thermal pane. The lower thermal conduction and convection rates of Argon further increase the window insulating values. Include Argon Gas in combination with Low-E Glass for maximum benefit.
