In modern sunroom projects, the goal is no longer just to enclose a space, but to transform it into a bright, spacious, and year-round comfortable environment. Door systems play a critical role in achieving this comfort, especially in projects with large openings. This is where thermally broken aluminum Lift & Slide doors stand out as one of the most reliable and suitable solutions for the GRANDE Sunroom system.
Unlike traditional sliding doors, Lift & Slide systems do more than move horizontally. When opening, the panel lifts slightly before gliding along the track. This mechanism allows the door to fully compress against the frame when closed, creating a high level of air tightness. As a result, wide openings are achieved without sacrificing insulation and performance when the system is closed.
The use of thermally broken aluminum profiles is a key factor in making the GRANDE Sunroom suitable for year-round use. Thermal break technology prevents heat transfer between interior and exterior aluminum surfaces, reducing heat loss during winter and balancing solar heat gain during summer.
These systems are designed for four-season performance and offer a high level of energy efficiency. Despite large glass surfaces, the interior temperature of the sunroom remains stable, and the space never feels like a closed or confined room.
One of the main requirements in GRANDE Sunroom projects is the ability to safely and smoothly operate large glass openings. Lift & Slide systems are specifically engineered for this purpose. Each panel can support up to 660 lbs (300 kg), allowing the use of large insulated and tempered glass panels with ease.
The system supports panels up to 118 inches (3000 mm) in height and 98 inches (2500 mm) in width, making Lift & Slide doors ideal for villas, large sunrooms, restaurants, and hotel projects. Configurations can include up to three panels sliding in one direction or six panels total when opening from both sides.
Lift & Slide doors in GRANDE Sunroom systems are typically paired with insulated tempered glass, such as ¼” + ½” air space + ¼” (6+14+6 mm) configurations. This setup provides thermal insulation, safety, and acoustic comfort. Even with large glass panels, the system remains stable and easy to use on a daily basis.
In addition, Lift & Slide doors can be configured with Low-E coated insulated glass. Low-E glass reflects interior heat back inside during winter while reducing solar heat gain in summer. This significantly improves energy efficiency and creates a more stable indoor environment throughout the year. Despite expansive glass surfaces, the space does not feel cold in winter or overheated in summer.
Optimized system weight per square foot is another important engineering advantage, making this combination suitable for wide-span projects and even rooftop applications.
When open, Lift & Slide doors minimize the boundary between indoor and outdoor spaces. Natural daylight flows in, air circulation improves, and the sunroom seamlessly transitions into an open terrace. When closed, the system’s high level of air tightness minimizes wind, cold air, and noise intrusion.
This balance transforms the sunroom into more than a seasonal space. It becomes a true everyday living area, usable during snowy winter days as well as warm summer months.
When the structural strength of the GRANDE Sunroom is combined with the technical performance of Lift & Slide doors, the result is not just a simple enclosure but a fully functional residential or commercial space. These systems are widely used in villas, restaurants, hotels, and large public areas as a long-lasting and reliable solution.
Thermally broken aluminum Lift & Slide doors are more than just operable elements within the GRANDE Sunroom system. They define how the space functions. When high load capacity, large size capabilities, Low-E glass support, four-season insulation, and effortless operation come together, the sunroom becomes a true year-round living space.
If your project requires wide openings, maximum glass visibility, and uncompromised comfort, a GRANDE Sunroom equipped with Lift & Slide doors offers a balanced and long-lasting solution.
Lift & Slide doors lift slightly before sliding, allowing the panels to fully seal when closed. This provides better air tightness, insulation, and overall performance compared to standard sliding doors.
