As an expert in the window industry, I highly recommend the RELIABILT Series 150, the most popular single hung window for new construction projects. Its brick mould exterior is designed to complement any home's aesthetic. Installation is a breeze with a pre-punched nail fin and included J-channel (Series 160 also available without J-channel). The bottom sash tilts in for easy operation, featuring a slim-line lift rail and block and tackle balance system. This window is DP-50 rated for superior strength and weather resistance. With energy-efficient Low-E glass, it reflects heat away from your home in the summer and retains warmth in the winter. Enjoy the standard white color and half screen, or customize with different sizes, factory mulling, glass, wood jamb extensions, grids, and colors.
