Project Portfolio
This project is located in Salt Lake City, it's a newly built private house. Since the project is in a region with cold winters and hot summers: high and dry sunburn in summer and strong winds that can whip through the winter, we need to provide the new house with enhanced energy efficiency and help our clients stay comfortable throughout the year. Our experts decided to use thermal break aluminum profiles with a double-glazing system.
Doorwin Heavy-Duty Thermal Break Bifold Door
The existence of these doors made the exterior area became the perfect continuation of the interior room. With Low-E laminated double glasses, the bifolds create a modern residence feeling while providing superior functionality.

Other than the bifold door, all the windows for this project were provided by Doorwin, too. Including the thermal break tilt & turn windows and trapezoid windows, all products have the same specifications as the bifold door. Considering climatic issues and the design needs of our customers, we offered a customized opening system with the upper half fixed window and the lower half tilt and turn window.

Custom-made Trapezoid Windows Besides the tilt and turn windows, we also offered trapezoid windows to fit the overall architectural style.

Two colors on one window or door Doorwin's one-window-two-colors option is available on all product lines and window styles.In this case, the client wants to add white windows and doors for a timeless look and to meet the overall interior decoration, but white doesn't compare to the exterior aesthetic. So, we give him the one-window-two-colors solution with black exterior frames and white interior frames. This solution completely fulfilled our client's wish.

Our doors include multiple rigid rubber seals and draught excluders to ensure that you get nothing but sunlight passing through your doors. Thermal break aluminum profile system utilizes the latest polyamide thermal barrier technology. This advanced profilt technology creates a thermal transmittance barrier between the cold outside and the warm inside keeping your home warm and comfortable even in the coldest weather. Glass specification is key when affecting the products thermal performance as it generally accounts for 80% of the surface area of the product. Each door set carries double glazed units incorporating Low E toughened safety glass as standard manufactured and tested in accordance with european and north american standards. The glass options available all vary in their individual thermal performance with glass unit center panel U-values starting at 1.6W/m2k,going down to 1.2W/m2k.

03 / Profiles Doorwin applies the best thermal break aluminum for ultra-large bifold patio doors. Thermal break aluminum is a material that applies a polyamide bar (PA66 Nylon) between the interior and exterior aluminum to stop heat transmission, also known as thermally broken aluminum. The polyamide bar is usually non-metal. The polyamide we use is from the world-famous brand Technoform Bautec™. Thermal breaks have decreased aluminum frame U-factors (heat loss rate) from roughly 2.0 to about 1.0 Btu/hr-sq. ft-°F. In hot climates. Our thermal break aluminum is more than 1.4 mm in thickness, which is much thicker and stronger than most companies.

04 / Glazing
For glass, we provide fully tempered glass as our standard options. With US standards and NFRC certifications, our energy-efficient integrated glazing units (IGU) feature double or triple panes glasses, warm-edge spacers, argon gas fill, Low-E coatings, and fully tempered glass, greatly improve the energy efficiency of the entire door. They can not only create a comfortable and natural indoor environment but also save electricity bills and heating bills around 300~500USD per year according to your whole building's fenestration areas. That's a real bargain compared to choosing a regular glazing set.

05 / Hardware & Colors
For windows and doors, hardware is as important as the engine is to the car. The continuous technological innovation of the European hardware industry has strongly promoted the performance improvement and functional innovation of windows and doors.
