Highlights of Ultra-Narrow Frame
We achieve grand dimensions with sleek, barely-there frames. At Doorwin, our trending designs are powered by state-of-the-art German and Belgian components. Each element in our ultra-narrow frame series undergoes rigorous certification and testing to ensure it meets the high standards of the Doorwin line.
1. Windows are a breeze to clean and less likely to gather dust behind the hinges.
2. The rubber strip remains intact, enhancing the overall sound insulation, air tightness, and water tightness of the window.
3. The Sobinco Chrono Invision with concealed hinges offers exceptional strength and durability without compromising on style.
4. A slim frame deserves a slim handle. Our escutcheon-free handle eliminates the traditional cover plate for a sleek, modern look.
