Crank out windows are one kind of casement window that is hinged at the side and open outward like doors but with a hand crank, and they operate by the crank system. They are ideal for hard-to-reach places (eg. above the kitchen sink) as the crank design allows for easy opening and closing. And the screens normally are placed on the inside of the window, where they are more protected from the elements.

Doorwin WOOD+ 163s Crank Out Casement Windows provide excellent ventilation. Superior energy efficiency due to compression seal technology. Then let me tell you the advantages of this series of products.

In this series of products, our best-selling profile is alu-clad wood, because the crank windows are the classic design and high-end products, customers don't just want the retro look, they also want good energy-efficiency performance. Solid wood is the best insulation profile, it is favored in many residential applications because of its appearance and traditional place in house design. From a thermal point of view, wood-framed windows perform well with frame U-factors in the range of 0.3 to 0.5 Btu/hr-sq. ft-°F. But the disadvantages are also obvious, solid wood is more prone to damage and corrosion, requiring higher maintenance costs, so we clad the exterior face of the frame with either vinyl or aluminum, creating a permanent weather-resistant surface.

Clad frames thus have lower maintenance requirements, while retaining the attractive wood finish on the interior. Many clients would place the alu-clad wood profile as the first place on their list, but there is only one disadvantage, which is the overall cost may be too high.

So according to the market needs, Doorwin also provides thermal break aluminum profile (For budget-friendly plans) crank out casement windows in various sizes, contact us for details if you have any recent plans.

Red Oak Alu-clad Crank Windows for a School Project In Kentucky

This school project is a complex made up of sophisticated classrooms, dorms, restaurants, and venues. It demanded windows and doors that would maintain a good energy-efficient performance and provide a classic aesthetic atmosphere.

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.

Doorwin products are made from the strongest material for windows and doors, meaning they have the strength and size capacity for this project. We are an industry leader in high-end aluminum & solid wood windows and doors with 15 years of experience, so you can trust that our products are built to last. And with 25 years of warranties in the business, we can offer you and your client peace of mind.

Solid Wood Entry Doors

In this project, we also provided three solid wood entrance doors. Traditional school door patterns with a big square peephole added architecturally authentic elements to match the whole building’s atmosphere.

Glazing Configuration

Because the project is complex including classrooms, dormitories, cafeterias, and other functions, it needs a good energy-efficiency performance. We have had a lot of projects in the USA and Canada before, so we fully understand the local building code requirements. Due to the climatic characteristics where the project is located, there are very clear requirements for the insulation performance of windows, so our products have the NFRC certifications to ensure that your project will pass the inspection after completion of the project.

We decided to go with double glazing. 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 around 300~700USD per year according to whole building’s fenestration areas. That’s a real bargain compared to choosing a regular glazing set.

Doorwin’s Hardware & Accessories

For the Hardware System, Doorwin uses Siegenia multi-point locks, hinges, and handles from Germany. With top burglar-resistant, the handles come with a long backplate in solid aluminum. The cylinder is practically inaccessible and the long backplate is almost impossible to remove. And the high-quality components, each is capable of sustaining 400lbs for high security and longevity. The friction stay is tested for more than 400,000 cycles, to put this in perspective, a window that is opened and closed 10 times a day should last at least 100 years before failure.

The multi-point locks system also provides better sealing and contributes to the insulation performance of the whole building. Together with Technoform Bautec’s insulation edge bond and sealant strips, these make up the top insulation and energy-saving performance of our products.

Doorwin’s Full-custom Specialty Shapes Service

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.

Free Design Assistance

With our own expertise, we provided the no-cost design development and contract documentation with CAD & BIM drawings, including elevation, details about the project, and installation help.

Before production, we will provide accurate sample drawings, which will clearly show the cross-sectional pattern, size, opening method and direction, pattern of the warm spacer, and the installation nodes. We will not go into production until you have signed off on the drawing to ensure that you receive a final product that meets the exact requirements of your project.

Guarantee the durability of products for 25 years

With high-productivity factories, we save your time on delivery

03 / Minimum Manufacturing Time

Thirdly is about the manufacturing time. It’s common hesitation when you buy windows from a foreign company. I would like to send you pictures and videos to have a look at our factories. We can finalize the production in about 18 days and shipping to you cost 30 days if it’s an urgent project. In about 45 days you will receive your windows. We are taking the same manufacturing daytime as you buy locally.

Our products are manufactured in 3 wholly owned manufacturing plants across China, a large state of the factories, sufficient to supply the largest projects, whilst remaining competitive. Over 100,000㎡ factory area with 500,000㎡ /year production capacity, so that means we can make the fastest possible production and fastest delivery of our products to meet clients’ time demands.

Factory-to-home direct sales,1/3 of the price among your local dealers in the EU & USA

04 / Save Overall Cost

Fourthly is cost. The most concerning problem is cost. We offer transparent pricing for our customers. The price we offer is the price you will pay after the final purchasing decision, with no additional or extra cost. You can compare our prices with local manufacturers.
