Energy Efficient

Since 80% of a window is glass, substantial heating and cooling savings come from improved glass performance. Combinations of UV-filtering Low-E glass, argon gas, and unique spacer system dramatically enhances energy efficiency. Reduce solar heat gain by more than 49% while increasing R-value and maintaining a warmer glass temperature in the winter. Castle Rock offers a variety of ENERGY STAR qualified products. Consult one of our trained professionals for a free estimate on the optimal glass package for your home and climate zone.
