Bay/Bow Window Exclusive Features

  • Weather Tough

    Our proprietary vinyl capping system ensures that your bay or bow window is impervious to the damaging effects of wind and water erosion. All bay and bow solid wooden window frames are capped with vinyl, meaning that your window is as safe from the elements as it can possible be.

  • Engineered With Support In Mind

    Your bay or bow window comes with an insulated seat board with a tri-layer base. An interior stain-ready 1-1/4 inch oak or birch layer makes for an attractive seat or display area. An internally concealed turn-buck/cable system anchors your window to the structure of your home with a 1/4 inch steel cable, preventing sagging and unwanted horizontal bowing.

  • Flexible Configurations For Your Home

    Our bay and bow windows can be configured with anywhere between 3 and 9 windows, at 15, 30, 45 or 90 degree angles, meaning that your bay or bow can be as compact or expansive as your home will allow. All panels have optional casement or double-hung window configurations for the best usability and fit.
