This Series 150 RELIABILT new construction single hung window is a popular choice among homeowners due to its brick mould exterior that complements any home's style. It is designed for both new construction and remodeling projects and can be easily installed with a pre-punched, integrated nail fin and J-channel included (Series 160 also available without J-channel). The bottom sash features a tilt-in design and operates smoothly with an integrated, full-length, slim-line lift rail and a block and tackle balance system. With a DP-50 (Design Pressure) rating, this window is suitable for windows up to 36-in W x 74-in H. Its energy-efficient Low-E glass helps reflect the sun's heat away from your home during the warmer months and retains warmth inside during the colder months. The window also boasts a 5/8-in contoured grid pattern between the glass panes, adding style to your home without the extra cleaning hassle of exterior grids.
