German Blood in Doorwin’s Windows and Doors

At Doorwin, we are committed to providing our clients with nothing but the best, and that includes the hardware and accessories that accompany our windows and doors. We understand that every detail matters when it comes to creating exceptional living spaces, which is why we have chosen to partner with leading German hardware manufacturers to elevate the performance and functionality of our products.

Our German-imported hardware system stands as a testament to precision engineering and unparalleled craftsmanship. The hinges, handles, and sealings are meticulously crafted to ensure seamless operation, enhanced security, and long-lasting durability. With a focus on innovation and quality, these top-of-the-line components perfectly complement the aesthetics and performance of our premium fenestration solutions.


Moreover, the combination of hardware and Technoform™ sealing strips contributes to superior watertightness. This means that our windows and doors effectively shield your home from the elements, providing excellent protection against rain, wind, and drafts. The added protection not only enhances the durability of our products but also significantly improves energy efficiency by preventing heat loss during colder months and maintaining a comfortable indoor environment.


By partnering with reputable German hardware manufacturers like Siegenia, Roto, and GU, we not only guarantee the exceptional quality and performance of our products but also demonstrate our unwavering commitment to providing our clients with the finest fenestration solutions available. When you choose Doorwin, you can rest assured that you are investing in windows and doors that are engineered to stand the test of time and elevate your living experience to new heights.

Super Efficient Glazing Units

The U-factor measures how effectively a window can prevent heat transfer, with lower values indicating better insulation. Our U-factor of 0.22 surpasses industry standards, demonstrating our commitment to providing the most energy-efficient windows on the market. By incorporating the highest quality hardware and sealing technology, we ensure that our windows maintain an airtight seal, preventing any drafts or air leakage that could compromise energy efficiency.


In addition to our German hardware, our double-pane tempered glazing sets play a crucial role in achieving such high energy performance. The double-pane design features two layers of glass separated by a spacer, filled with argon gas. This configuration significantly reduces heat transfer, preventing heat from escaping during winter and keeping your home cool during summer. The Low-E coatings further enhance insulation by reflecting infrared heat while allowing visible light to pass through.

The combination of our German-imported hardware, advanced sealing technology, and energy-efficient glazing sets results in windows with outstanding thermal performance. Not only do they contribute to a comfortable and consistent indoor temperature, but they also help reduce heating and cooling costs, making your home more environmentally friendly and budget-conscious.

Custom Grilles Design

At Doorwin, we understand that every home is unique, and our custom grille design allows you to add a touch of elegance and timeless charm to your windows and doors. For this particular project, we offered windows with 4-grid patterns, which perfectly complemented the classic and sophisticated look of the duplex.

The 4-grid pattern is a versatile choice that adds a sense of balance and proportion to the windows, creating a visually appealing aesthetic. Whether your style leans towards traditional or modern, the 4-grid pattern blends seamlessly with various architectural designs, enhancing the overall curb appeal of the property.


Moreover, we also provided a stunning 8-grid pattern for the double patio doors, creating a captivating entrance with a touch of retro charm. This distinctive grille design not only adds character to the doors but also offers a sense of grandeur and sophistication, welcoming visitors with a touch of elegance.

Our custom grille design options are not limited to specific patterns; we can tailor them to suit your unique preferences and architectural needs. Whether you desire a more intricate or simplistic pattern, our team of experts will work closely with you to bring your vision to life.
