Bi-fold Doors

WeatherMaster Plus™ Bi-fold Door System

Sunspace has redefined outdoor living with the revolutionary WeatherMaster™ Plus Bi-Fold System—a fully customizable solution that combines wall systems, ventilation, insect protection, passage doors, bi-fold doors, and seasonal or year-round options into one seamless design. Engineered with European innovation, this system features above-ground bottom-running operation with various threshold options, ensuring versatility and durability. Its custom hardware and design support maximum load capacity, offering slim sightlines, oversized doors, and minimal profiles for an elegant appearance. The system is highly adaptable, with doors that can open inward or outward using the same profiles. The sash and outer frame share the same depth, delivering exceptional thermal performance. Paired with custom hardware, this inline design ensures both high performance and stunning aesthetics. The WeatherMaster™ Plus also includes WeatherMaster™ Vertical-4-Track windows as a standard feature, with options for single-glazed tempered glass or fully thermal insulating glass, making it the ultimate solution for comfort, style, and functionality in your outdoor space.

Features & Benefits

Compact And Aesthetically Pleasing Profile

Over the years, bi-folding doors have evolved to become slimmer and more discreet. Advances in materials have made modern frames smaller while maintaining exceptional strength. Unlike traditional sliding patio doors, bi-folding doors neatly fold to the side, requiring minimal space when open. This design allows you to fully open an entire wall, creating seamless access to your garden and maximizing visibility. The result is a stylish and practical solution that enhances both the functionality and aesthetics of your home.

Allow For More Natural Light

Thanks to their slim frame profile, bi-folding doors offer a much larger window surface, allowing significantly more light to flood into the room compared to traditional windows or doors. Even when closed, they provide an unobstructed flow of natural light, ensuring there’s no compromise on brightness. When open, the space becomes truly expansive, with nothing standing in the way of daylight. Bi-folding doors are an ideal choice for rooms that lack natural light or spaces you want to enjoy more fully throughout the day.

Superior Security And Safety

While bi-fold doors may appear fragile due to replacing a solid wall with glass, they are actually highly secure. In fact, they are commonly used by businesses in commercial environments for this very reason. Bi-fold doors feature multiple security elements, such as multi-point locks, sturdy frames with heavy-duty hinges, and, in some cases, laminated triple-glazed glass. This toughened glass is much harder to break, and the doors are designed so they can’t be levered off the hinges. Together, these features make break-ins difficult and serve as a strong deterrent for potential burglars.

Add Value To Your Home

It’s always reassuring to know that your home is increasing in value over time, even if you’re not planning to sell. This is an important factor to keep in mind when considering your next home renovation. Bi-folding doors are incredibly versatile, complementing any style of home—whether it’s a classic Victorian or a sleek, modern, minimalistic design that’s trending today. Their simplicity and practicality can elevate your everyday living experience. Bi-fold doors brighten up dark spaces and provide seamless access to your garden, effectively blending your indoor and outdoor areas for a more open, connected feel.

Low Maintenance But Highly Durable

Bi-folding doors, particularly those made of aluminum, are built to withstand temperature fluctuations year-round. Whether it’s hot or cold, the frames won’t warp or bend, ensuring long-lasting durability. These doors are highly thermally efficient and can also endure strong gusts of wind. Best of all, their maintenance is minimal—requiring only occasional cleaning and a light application of oil to keep them in optimal condition. This easy upkeep helps extend their lifespan, making them a practical and reliable addition to any home.
