Installation is easy with us. We have several international patents that reduce labor costs including our unique flanges and assembly-type tubular design. It helps to install the windows easily. What sets us apart from our Chinese counterparts is that all our products are equipped with nail fin structures for quick and easy installation. Labor costs during installation may exceed the window and door prices, therefore, the longer the project takes, you are losing more money. We help our customer make the work done in a shorter time. In this way, it saves more money for them.

04 / Save Overall Cost

We offer a transparent pricing model for our customers. This means that when you finalize your purchase, the price you pay is the same as the one we quoted you in the beginning. We do not charge additional fees or extra costs.
You can compare our prices with those of local manufacturers and see for yourself why our products are so much cheaper than theirs. This is because China’s manufacturing industry has grown to be a global manufacturing central axis that has rewritten the global landscape with its own strength. Now not only do we lead the world trend in crafting but also focus on design and aesthetics. Now I can proudly tell you that we can offer top-quality products at a third of the price of local merchants in Europe and America.

When you buy windows and doors in China, there are several concerns that you need to be aware of. First, the products you choose should be made with top-quality materials and performed well to ensure that they last long. Second, the price must be affordable so that you can save money. Third, you should also look out for hidden costs, such as transportation fees and installation charges. Finally, it is important to find a reliable partner who can provide after-sales service if anything goes wrong with your purchase.

We have been providing our partners with top-quality products at affordable prices and we have worked hard to build up our reputation for providing excellent customer service through our customer support team who are trained in both domestic and international standards.

Doorwin is a solution-oriented company that provides high-quality door and window solutions for the North American market. We have been in business for over ten years, and during that time we've developed a reputation for providing our clients with professional plans and meaningful design that meets all of their highly customized demands.

We are responsible for controlling the budget and ensuring that the overall plan is within cost parameters. This includes providing schematic designs to help clients determine products within those parameters. For example, it may be possible to use lower-cost products in inconspicuous locations to reduce the overall budget. If the direction of sunlight is not under long time sunlight, do not use Low-E glass; use PVC windows or aluminum windows instead of solid wood windows in unimportant rooms such as toilets or storage rooms.

Energy Efficient Windows & Doors

The word “energy efficiency” is undoubtedly one of the most frequent words in recent years. I have heard the saying that in the next 20 years, the most energy consumed is not industry, not transportation, but our house. The energy consumption of doors and windows occupies a large proportion of the houses’ energy consumption.

Doorwin has been focusing on this issue for many years, and we have created several energy-efficient products to solve this problem. Every type of Doorwin’s product is made for higher performance of energy efficiency, reaching the highest level of US and EU standards, no matter the sound and thermal insulation or the air and water tightness. Doorwin’s energy-efficient Integrated Glazing Units featured 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 around 100~300 USD per month according to your whole building’s fenestration areas. That’s a real bargain compared to choosing a regular set.

Guarantee 0 Damage Packaging , Detailed Instructions for Easy Installation

As one of China's largest exporters of windows and doors, we know the importance of proper packaging. When your product arrives on site, it's likely to be handling a lot of stress. If it's not packaged properly, it can break during transport and delay your installation schedule. We take every precaution to ensure that this doesn't happen—we pack each window individually and in four layers, then place them in non-fumigated wooden boxes for protection. The containers are filled with shockproof measures to protect your products during long-distance transportation.
We are very experienced in packaging and protecting our products to ensure they arrive at the sites in good condition. What the client concerns, we concern most.
