Single Hung Windows
Single-hung windows consist of two window sash, where only the lower sash is operable (slides up and down).
Impervious to rot and insects, the ENVIROGUARD™ block and tackle single-hung window series is not only pleasing to the eye but also durable. Constructed with the highest quality cellular PVC, these windows have all the natural characteristics of wood, including great appearance–without the shortcomings of wood. They won’t rot, peel, splinter, decay, absorb moisture–and they have enhanced screw-holding power.
Unlike vinyl windows, our cellular PVC single hung windows can be painted, look like real wood, and offer more glass space.
