Project Showcase

At Doorwin, we are thrilled to have had the opportunity to work on such a prestigious project as the renovation of the Prime Minister of Afghanistan's office building. We understand the importance of creating a space that is not only energy-efficient but also welcoming and aesthetically pleasing.

Our team worked closely with the project architects to ensure that our aluminum clad wood tilt and turn windows not only provided exceptional thermal performance but also complemented the building's unique character. We took great care to incorporate modern architectural elements into the window design, which not only enhanced the building's overall look but also improved its functionality and energy efficiency.

Doorwin WOOD+ 86s Alu-clad Red Oak Tilt & Turn Windows

The WOOD+ 86s Alu-clad Red Oak Tilt & Turn Windows operate using a unique tilt and turn mechanism that allows them to be opened inward for easy cleaning and ventilation. Here's how they operate:

· Tilt mode: In the tilt mode, the top of the window tilts inward from the bottom, creating a small gap for ventilation. This mode is ideal for situations where you want to let in fresh air without fully opening the window.
· Turn mode: In the turn mode, the window swings inward like a door, allowing for maximum ventilation and easy cleaning. The window can be locked in this position for added security.

Doorwin's MultiMate Mulling System - The easiest way to connect multiple windows together seamlessly.

With our new MultiMate Mulling System patent, we've made it easier than ever for our clients to connect multiple windows together to create a larger window system. Our unique mulling system allows for seamless integration between windows, creating a smooth, clean line that enhances the overall look and feel of the window system.

The MultiMate Mulling System is designed to be easy to use and install, with a simple, intuitive interface that makes it easy to connect and disconnect windows as needed. The system is also built to be durable and long-lasting, ensuring that our clients can enjoy the benefits of a seamless window system for years to come.

It was our goal to create an environment that would inspire productivity and creativity while also being comfortable and inviting for visitors and staff alike. Our team paid close attention to every detail, from the design of the windows to the selection of materials, to ensure that the end result was a space that exceeded expectations.

We are proud to say that the renovation of the Prime Minister's office building was a resounding success, and we were honored to have played a part in it. At Doorwin, we believe that every project is an opportunity to showcase our commitment to quality, craftsmanship, and innovation. We look forward to continuing to provide high-end, energy-efficient windows and doors for commercial projects around the world.

The frames of these windows are made from high-quality red oak wood, which is known for its strength, durability, and natural beauty. The wood frames are coated with a protective layer that helps to prevent moisture and heat from penetrating the wood, ensuring long-lasting performance.

To switch between the tilt and turn modes, simply turn the handle on the window frame 90 degrees. This will engage the appropriate mechanism and allow you to open the window in the desired mode. The windows also feature multi-point locking systems that provide enhanced security while improving insulation and energy efficiency.

The aluminum cladding on the exterior of the frames provides additional protection against the elements, ensuring that the windows are low maintenance and resistant to weathering, corrosion, and fading. The cladding is also available in a range of colors to match any design preference. As for the cost, a regular wood casement window average costs 600-800$ in the US market while our tilt and turn windows just need 300-600$ with higher standards in manufacturing, hardware, and energy efficiency abilities.

At Doorwin, we take energy efficiency very seriously, and we understand that windows play a critical role in a building's overall energy performance. For the renovation of the Prime Minister of Afghanistan's office building, we used our aluminum clad wood tilt and turn windows, which are designed to be highly energy-efficient with a 0.22 U-factor, our windows are passed the NFRC & Energy Star certifications and are 100% made with standards of the US.

02 / Multi-point locks: Our tilt and turn windows are equipped with multi-point locks that provide better insulation and increase security. These locks distribute the weight of the window evenly along the frame, creating a tighter seal and reducing air leakage.

03 / Finest wood materials: We use only the finest wood materials in our windows, including pine, oak, and mahogany. These materials are chosen for their strength, durability, and energy-saving properties. Our windows are also coated with a protective finish that helps to prevent moisture and heat from penetrating the wood, ensuring long-lasting performance.

At Doorwin, we take great pride in our ability to provide high-end, custom-designed windows and doors for commercial projects of all sizes. Our team of skilled designers and craftsmen work closely with our clients to create unique, customized solutions that meet their specific needs and requirements.
