Let’s in what you want and keeps out what you want out! Introducing Energy Savings 1.1. The most energy efficient glass block in the market today.

U-value of the NEW Energy Saving 1.1 glass block is .19 Btu/hr ft °F

Our patented design incorporates 2-sheets of low-emissivity coated glass inserts sandwiched inside the block creating a two-chamber system. The Low-E coating reflects heat back to its source helping your business or home to stay cooler in the summer and warmer in the winter. Air in the 2-chambers is replaced with Argon gas. This noble gas, with its inherent thermal conductivity value, also contributes to these blocks increased energy efficiency.
