Overview
The SV-7700 Fold Thermo is a bi-fold thermal break system with a streamlined, linear design that delivers outstanding insulation and waterproofing performance. Ideal for large openings, it offers flexibility with multiple configuration options, supporting both odd and even numbers of sashes that can open either inward or outward. This system is perfect for residential spaces as well as food and beverage establishments (such as restaurants and cafés).
The system's load-bearing capability is ensured by the sash rolling smoothly on the bottom rail, while the specially designed door sill facilitates easy access for individuals with disabilities. Additionally, the corner column profile attaches directly to the sash, providing an unobstructed view when the system is open.
