Product Description

This project is located in the City of Palo Alto, CA, which is a newly built private villa. Because of the warmer climate in the area, the client was in desperate need of some very energy-efficient windows. So, we coupled this house with Doorwin exclusive alu-clad oak wood crank windows with double-pane Low-E laminated glass sets. Solid wood material provided raw power for energy efficiency, and crank casement openings gave the compression seal function to enhance the effect.

Doorwin WOOD+ 163s Alu-Clad Crank Out Casement Windows

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 offers the best alu-clad wood materials with higher strength and thermal insulation performance. This system combines modern aesthetics with top-of-the-line hardware and materials. They are higher performing in terms of thermal efficiency, noise reduction, and safety compared with other products in the market. 

Doorwin WOOD+ 163s system is with double, laminated, or triple glazed for superior thermal and sound insulation. Our products 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 ensure higher performance and stability of our products
 

DOORWIN Compared to Other Brands
 

 

 

01 / Profiles & Colors
In this project, we provided alu-clad white oak as the main material for the windows. As we all know, solid wood is the most energy-efficient material, which is exactly what the customer wants. From a thermal point of view, wood-framed windows perform well with frame U-factors in the range of 0.3 to 0.5.  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.

As the exterior aluminum cladding, it has lower maintenance requirements, while retaining the attractive wood finish on the interior. Our Aluminum cladding with an advanced seamless welding joint technique makes the four corners of the aluminum cladding welding smoothly and barely can be seen. Resulting in not only a stronger weld but also creating a prettier finish.


For color options, the client wants to add white windows for a timeless look and to meet overall interior decorations, however, if it is painted white on the exterior window frame and sash, the painting cannot withstand the long years of aging and will increase the maintenance cost. So, we provided a solution with double colors. black exterior frames and white interior frames.

Not only black and white, but we also provide polyester powder coated 250+ RAL colors (with extra metallic and polished effects) to meet your infinite possibilities in custom design. If you prefer, you can even send us a color card and we will paint the windows exactly the way you want them to be. 

For wood species, we are able to provide many qualified wood types, such as pine, oak, cherry, larch, maple, mahogany, teak, etc. We apply German environmentally friendly water-based paint to meet the need of health while remains the vivid texture of the wood. For wood species, we carefully select the quality woods from their origin places. Our oak and pine are from USA or Canada, teak is from Southeast Asia.



02 / Glazing
All of our windows and glass are in accordance with the NFRC standards of the United States. We will customize the glass requirements according to different regions, climates, and local inspections.

For the City of Palo Alto's warm climate, this project 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 300~500USD per year according to your whole building's fenestration areas. That's a real bargain compared to choosing a regular glazing set.



03 / Hardware
For the Hardware System, Doorwin uses Made-in-USA multi-point locks, hinges, and handles. The handle is made of high quality stainless steel, and the bearings inside let you enjoy smooth operation. 

04 / Removable Screen Our screen frames are made of the same material as window frames, perfectly matching the overall designs, and the removable operation makes it easier to clean. High-grade nylon provides a higher durability for screens and will not be damaged by common bumps and stretches.

Crank Casement Window VS Sliding Windows
 

01 / Physical Differences & Ventilation Crank windows or crank casement windows are opened and closed with a crank, its mechanism system supports its outswing up to 90 degrees, and the sash can catch and direct cross breezes into the house for increased ventilation. Sliding windows or horizontal sliding windows, the sashes slide horizontally on the rails, and only half of it can be opened, so this functional reason makes sliding ones reduced ventilation.

02 / Energy Efficiency Absolutely, the crank casement window has better energy efficiency due to the compression seal between the sash and frame, which makes it the most efficient of all windows. 03 / Anti-weather & Tightness Because of the compression seal, the crank casement windows have the best air and water tightness and anti-weather function. And due to the rail operations of the sliding windows, they may not have the air and water tightness ability in extreme conditions (high wind, rain, and snow) as the casement windows.

04 / Prices
Usually, sliding windows are generally less expensive than crank casement windows. However, the energy savings from crank windows will surely pay for themselves over time. Furthermore, sliding windows don't provide adequate protection from the elements, and are harder to maintain than casement windows due to dirt buildup and friction.

Choosing the right window for your home and your particular needs is a subjective choice that will always vary.  If you are going to invest in new windows, feel free to contact us for professional support.
