The RELIABILT 150 Series single hung window is a top choice for new construction projects. Its brick mould exterior adds a touch of style to any home. Designed for both new construction and remodeling, this window comes with a pre-punched nail fin and J-channel for easy installation (J-channel not included in Series 160).

It also features energy-efficient Low-E glass that reflects heat in the summer and helps maintain warmth in the winter.
