Canadians face extreme seasonal shifts, from deep winter snow to sweltering summer heat, making outdoor spaces hard to enjoy year-round. WeatherMaster™ windows by Sunspace offer a flexible, durable solution, turning open-air areas into adaptable enclosures for any season. Whether it’s a gazebo in Muskoka or a porch in Calgary, these vinyl-glazed, four-track windows provide all-season comfort and style.
The design behind WeatherMaster™ windows
Every WeatherMaster™ window is built with a clear purpose: to deliver comfort, flexibility, and style in any season. From the materials used to the way the panels operate, every detail is engineered for performance in the Canadian climate.
View flex vinyl glazing
At the heart of WeatherMaster™ windows is a unique glazing material called View Flex vinyl. Unlike traditional glass, this advanced polymer is shatter-resistant, UV-protected, and incredibly light. It provides the appearance and clarity of glass but with added safety and resilience: ideal for harsh Canadian winters or summer storms.
Available in four tints (Clear, Smoke Grey, Dark Grey, and Bronze), View Flex gives homeowners full control over aesthetics, privacy, and solar protection.
Four-track adjustable panels
Each WeatherMaster™ window operates on a four-track vertical or horizontal slider system. This means you can stack the panels in multiple configurations to adjust airflow, light, or protection.
Want 75% ventilation on a breezy summer day? Slide three panels open and let the fresh air pour in. Need full protection from snow or wind? Close all panels tightly for a sealed, insulated barrier.
Full ventilation control (up to 75%)
One of the major perks of the four-track system is ventilation versatility. Unlike fixed windows or screens, you’re not stuck with an all-or-nothing setup. With WeatherMaster™, you decide how much of the outdoors you want to let in: on your terms, in any season.
Performance in cold weather
The long, frigid months of winter don’t have to mean abandoning your outdoor spaces. Designed to keep the cold out and the comfort in, WeatherMaster Windows allow you to enjoy your enclosure well beyond the traditional warm-weather season.
Maintains warmth by sealing out drafts
Canadian winters demand window systems that do more than look good, they must perform. WeatherMaster™ windows feature compression weather stripping and tight track seals that keep out drafts, snow, and cold air. When paired with insulated floors and ceilings in a 3-season room, they create a space that remains cozy late into the fall and early spring.
Won’t crack or yellow in sub-zero conditions
Unlike traditional plastic or glass windows, WeatherMaster™ vinyl is engineered not to crack or fog even in sub-zero temperatures. It’s designed to flex with the climate instead of becoming brittle. Homeowners from Ontario to Alberta report years of consistent clarity and performance, no matter the winter’s severity.
Comfort during warm months
When the temperature rises, your WeatherMaster™ windows adapt instantly, turning enclosed spaces into cool, breezy retreats without sacrificing protection.

Opens for full airflow
When the summer heat sets in, WeatherMaster™ windows easily transform enclosed rooms into breezy retreats. Slide the panels open to maximize cross-ventilation and enjoy a true outdoor experience while staying protected from bugs and pollen.
UV protection while maintaining visibility
View Flex vinyl blocks harmful UV rays that can fade furniture and flooring. This makes it ideal for rooms with natural wood, indoor plants, or upholstered furniture. The tint options help reduce glare while still allowing beautiful outdoor views.
Durability and ease of maintenance
Investing in WeatherMaster™ windows means choosing a system built to last through years of use, all while staying easy to care for.
Scratch-resistant, strong, and easy to clean
Life happens: kids, pets, weather, and everything in between. WeatherMaster™ panels are scratch-resistant and durable enough to withstand everyday use. Cleaning is simple: just a soft cloth with mild soap and water keeps them looking like new.
Built to last for years despite climate exposure
Unlike glass that may shatter or cheap plastic that clouds over time, View Flex is long-lasting and backed by a strong warranty. These systems are built for decades of performance, no matter how punishing the climate. When installed professionally by authorized dealers like BR Lifestyles, the system becomes a low-maintenance, high-reward investment in year-round outdoor living.
