Enjoy the beauty of Maine’s changing seasons — without the wind, bugs, or pollen. Sunspace by Sunrise Sunrooms installs WeatherMaster Windows, a versatile vinyl-pane 4-track window system that turns your porch, screen room, or patio into a comfortable living space for up to three seasons of the year.
What Are WeatherMaster Windows?
WeatherMaster Windows are a custom-built vertical or horizontal 4-track system using View Flex® vinyl glazing — a safe, flexible, and crystal-clear alternative to glass. Designed for Maine’s varied weather, these windows protect you from spring pollen, summer insects, and chilly fall winds while letting in fresh air and natural light.
Each panel easily slides to create up to 75% ventilation, giving you full control over airflow and comfort in your outdoor space.
