For years, Cardinal Low-E glass has been setting the standard for energy-efficient glass. They are the glass supplier of choice for top of the line window and door manufacturers in the United States.  Heritage®’s 12 plus year relationship with Cardinal Glass shows our commitment to quality and also our passion for improvement.

We now carry as our stock inventory glass, Cardinal LoE-366 (low E cubed 366). This is the new generation of low-E glass that reduces window heat gain by 64% compared to ordinary glass. The advantage of LoE-366 is that it reduces the SHGC to levels of tinted glass (LoE-240) without the loss of light transmittance that comes with tinted glass.

In addition to Cardinal LoE-366 and LoE-240, we are now offering Cardinal I81 glass which offers triple pane performance in a double-pane window.  For more information on I81 values please visit Cardinal's website at http://www.cardinalcorp.com/products/coated-glass/loe-i81-glass/.
