The tilt-turn window, originating in Europe and popularized by passive-house and net-zero construction, is a window type with the unique characteristic of being both an inward-swing casement style window as well as a top opening hopper style window. The clever hinge and intuitive handle mechanism is specially designed to allow seamless switching between the modes via the orientation of the handle. Depending on the handle position, it can operate as a fixed window (handle in the 6 o'clock position), inward casement window (handle in the 9 o'clock position) or hopper window (handle in the 12 o'clock position). This window style combines the security, air-tightness, egress requirements and ease of cleaning of an inswing casement with the all-weather ventilation convenience of a hopper.

This product represents the latest evolution of our tilt-turn window featuring a solid oak frame and sash and exterior aluminum cladding. Solid wood is the preferred choice for windows due to its low thermal conductivity, strength to weight ratio, ease of finishing and appearance. Wood window can last generations, as evidenced by the many historic homes all over the world. That said, wood windows do require regular maintenance and can be susceptible to pests such as termites. Our wood treatment process produces a more durable wood that our internal testing has shown can withstand unprotected, direct exposure to the elements for 10-15 years before failure and can last a lifetime if properly maintained. However, for those that desire the ultimate in window technology, our top of the line wood windows feature exterior aluminum cladding alleviating all concerns with wood and the concomitant design considerations to mitigate them.

Competitive with the best in the industry, Doorwin Tilt-turn windows feature 4 sealing layers; a continuous rubber seal around the sash and three inner seals. Along with our pressure-equalized cavity drainage design, this product ensures outstanding performance even under the harshest weather.

Our energy efficient integrated glazing units (IGU) feature triple-pane glass, warm-edge spacers, argon gas fill, Low-E coatings and fully tempered glass. Different IGUs are available to meet the needs of different climates.

Doorwin is positioned to offer the finest value in quality tilt-turn windows. We seek to make durable, energy efficient and beautiful products accessible to all budgets. We strive to provide the best customer service experience with a dedicated design and engineering team for custom projects and a talented sales team that responds quickly to inquiries.

FAQ

1. Is the raw material stored in a climate controlled space for acclimation? For example, are there automatic spray misters monitored by sensors?

The wood material that we are using are all imported from Canada and America, which have been already treated professionally. Usually, the wood has been thoroughly air-dried and oven-dried to retain a certain percentage of moisture. We will control the moisture content of wood to meet the EMC of different climates, which helps to get better wood durability and strength. No possibility of deformation. Especially for the US market, we strictly follow the moisture content map.

 

2. What processes does Doorwin have to maintain quality control? Is the product inspected at regular intervals?  How about the cutting machines?  Is each shipment physically inspected before it leaves the factory?  Do you have manufacturing certifications like ISO?

We maintain a quality management system which meets the requirements of ISO 9001 as a minimum and develop, manufacture and check the products according to the rules of this system.

We set up very high inspection standards both for choosing materials and every production processes.

We request to sign quality assurance agreement with our material suppliers to ensure the materials quality, in production process self-inspection of each key part from cutting to frame and glass assembling as well as hardware installation must be a formal quality system of our factory.  Our QC will inspect the products at regular intervals. Last but not least we will test and inspect the finish products physically before they leave our factory to ensure that the products meet the agreed requirements, specifications, quality and performances.

Inspection photos, videos and the records from the in-process controls can be provided for evaluation.

 

Matching with the strict production processing control, every parts of material are picky chosen in high level. The lumber all come from the certificated supplier, and we use Henkel wood adhesive from Germany for the joints to ensure strength and low toxicity.

3. While it's good to have a warranty program, what are the specifics?  What is required to file a claim?  Is the warranty only for the original purchaser? Is it transferable?  Are there any warranty limitations?  What types of claims are accepted and denied? Who pays for freight?

Doorwin is responsible for the quality of the windows and door supplied and will provide a warranty for a period of Ten (10) years from the date of each shipment, against any manufacturing defects. The warranty is only for the original purchaser and non-transferable.

 

The warranty doesn’t cover any damage or defects caused by improper handling, installation, on-site storage, misuse or the Buyer’s failure to provide reasonable maintenance of the products

 

If the customer makes a claim or complaint due to damage or defects in manufacturing, materials or workmanship, photos and videos are required for evaluation. If it has been proven a defective product, Doorwin shall provide the replacement and all the expenses incurred therefrom, including the shipping shall be borne by Doorwin.

 

4. What if a window needs replacement but that window is no longer manufactured?  Do you provide a window of equal or higher value as a replacement?

Once any defective windows have been delivered, Doorwin will provide free replacements. If the window is no longer manufactured, we will provide replacements with higher value. All the expenses incurred therefrom, including the shipping shall be borne by Doorwin.

 

5. How long will it take from the time one submits a claim to receiving a replacement? 

When the customers report any quality problems, we will respond and give initial solutions within 24 hours, and provide a complete solution within 48 hours. If any replacement is needed, we will arrange it as a priority.

 

6. What are your precise U-factors and SHGC values?

Actually, a window’s U-value and SHGC value are determined by many factors, for instance, the window opening styles, frame materials and structure, glass configurations (the number of panes, the type of glass, the type of spacer, the type of gas filled), hardware quality, sealant quality, as well as the rating method, etc.

So if customers have special requirements on U-factor and SHGC value, there is no problem for us to achieve by adjusting the frame materials, glass configurations, etc. For example, the U-factor 0.30-0.32 could be reach, even lower. Moreover, the Bureau’s testing report could be available for customer’s necessary need.
