Sliding glass panels that turn your pergola into a four-season outdoor room. Slide them closed for a fully sheltered space in winter, spring rain, or windy autumn evenings. Slide them fully to one side in summer, and you are back to open-air living with nothing in the way.
The panels run on smooth, precision-engineered rails integrated into the Horizon frame. Each panel glides to either side independently, so you can open a single section for airflow, create a wide entry point, or stack them all away when the weather turns good. No tools, no seasonal install, no storage.
Closed, the glass blocks wind, rain, and cold while keeping the view completely clear. You keep the garden, the sky, and the sense of openness, but gain a weather-tight space you can use in every month of the year. Heat it with a patio heater in winter, and it becomes genuinely usable when everyone else has closed up their outdoor space until spring.
