Doorwin WOOD+ 163s system windows are certified by NFRC, CSA, and many other EU and NA Institutions for air permeability, water tightness, wind resistance, thermal conductivity, and noise reduction. Below, we will show some of our unique proprietary designs to confirm that Doorwin products have higher performance and stability than other competitors’ products on the market.

Here we are proud to present to you this case in Louisville, Kentucky! The fact that a school uses our windows shows that the quality and design of our products far exceed those of our peers.

In Louisville, the summers are hot and muggy, the winters are very cold and wet, and it is partly cloudy year-round. Our energy-efficient integrated glazing units (IGU) feature double-pane glass, warm-edge spacers, argon gas fill, Low-E coatings, and fully tempered glass, they can not only create a comfortable and natural indoor environment but also save electricity bills and heating bills. And the materials are Red Oak with aluminum cladding profiles, added custom simulated divided lites, specialty shape transom, and high-quality crank systems. All profiles and glazing are by U.S. energy-efficiency building codes

Assembly Tube Installation

Doorwin has developed a new patented technology that allows for quick installation of the window sash and frame or adjacent window frames without having to separate the glass and sash, then the glass doesn’t have to be removed from the window frame during transportation.

This technology makes the installation more efficient and the quality of the doors and windows more stable after transportation, making the whole process of transportation and installation much less costly.

Doorwin respects your visions and offers true freedom in design. We manufacture products based on your ideas and needs, every part including special shapes, hardware styles, and color choice is totally no additional charge. Everyone should understand the high demands of manufacturers that customize specialty shape windows, general manufacturers will charge extra fees for customization requests, but not Doorwin.

Longterm Warranty

In our opinion, good quality means never having to compromise. The high-quality aluminum and components that we use allow us without compromising structural strength. In other words, even with slim frames, we offer a high-performing product for you. Our research and development team made sure that you still get unrivaled thermal insulation, high performance, and top-quality hardware on the 10 YEARS WARRANTY. The TPS glazing ensures that no air leakage and fogging issues on products for 25 YEARS WARRANTY.

Safest Delivery

We export tens of millions of dollars of windows and doors to the U.S. every year, and we know that improper packaging can cause breakage of the product when it arrives on site, and the biggest loss from this is, I'm afraid, the cost of time, after all, workers on site have requirements of working time and it needs to wait for a new shipment to arrive in case of damage occurs to the goods.

So, we pack each window individually and in four layers, and finally into (non-fumigated) wooden boxes, and at the same time, there will be a lot of shockproof measures in the container, to protect your products. We are very experienced in packing and protecting our products to ensure they arrive at the sites in good condition after long-distance transportation. What the client concerned, we concern most.

Each layer of the outer packaging will be labeled to guide you on how to install, it to avoid delaying the progress due to incorrect installation.
