Afghanistan Prime Minister's Office Project With Alu-clad Wood Tilt Turn Windows

This project is for the prime minister of Afghanistan, so we value this opportunity to make a good impression on a new market. The idea was to turn a four-floor building built in the 60s into a highly energy-efficient office with a strong character given by using modern architectural elements.

All the fenestration systems were made with Doorwin’s exclusive oak wood with exterior aluminum cladding and high-performance Low-E glass. This well-crafted bespoke set enhances the distinctive look of this house. Every window’s placement, shape, and material add to the uniqueness of the whole building and make it safer and more functional for the owners.

The tilt and turn window can both tilt inwards at the top or open inwards from hinges at the side. This is the most typical kind of window in Germany, its native land. It is likewise widespread in many other European nations. In Europe, it is typical for these to be of the "turn first" kind. i.e., when the handle is counted on 90 levels the window opens up in the side hung mode. With the handle transformed to 180 levels, the window opens in the bottom open mode.
Doorwin’s premium tilt and turn windows are more resistant to blustery weather while maintaining functions like air-tightness, alternative ventilation way, and accessibilities; tilt and turn windows form a complete seal when fully closed, and they can be opened in the upper tilt way to ventilate at a minimum opening status, when there’s a good day, it can be opened as normal inward casement windows.


In this project, we chose red oak wood as the main profile for windows. Doorwin’s specially maintained wood windows can have a very long life. Our German environmentally friendly water-based paint protects the surface and allows an easy change in color schemes.

Wood windows own natural wood grain, a beautiful look and excellent insulation, and it adds a natural feeling to a home, which any other window material cannot compare. 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 aluminum, creating a permanent weather-resistant surface. 

Besides being energy efficient, wood windows are trendy and timeless. Wood boasts a sense of comfort and nature at home, which cannot be provided by fiberglass or aluminum. With origin unique wood grain, the beauty of wood doors goes beyond descriptions.

We are into the field of windows and doors for years; our professional manufacturing process and delicate workmanship make our solid wood windows and doors recognized by many clients. 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.

Hardware & Accessories

For windows and doors, hardware is as important as the engine is to the car. The continuous technological innovation of the European hardware industry has strongly promoted the performance improvement and functional innovation of windows and doors. Doorwin uses Roto 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.

Many people have asked similar questions -- what makes Doorwin attractive? That is a common and essential question. Well, for a construction professional like you, what you worry about are mostly 4 types —— Easy installation, maintenance free, manufacturing time, and overall cost.

Save your money on the installation costs

01 / Easy Installation

Firstly, is easy installation. We have several international patents to reduce clients’ labor costs, such as our unique flanges and assembly type tubular design. It helps to easily install the windows. You cannot easily find the nailing flange in other companies, which is 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, it means you are losing money. We help our customer make the work done in a shorter time. In this way, we save more money for them.

02 / Maintenance Free

Secondly is easy to repair.

03 / Minimum Manufacturing Time

Thirdly is about the manufacturing time. It’s common hesitation when you buy windows from a foreign company. We 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.

Energy-efficient and Environmentally Friendly

The word "energy efficiency" is undoubtedly one of the most frequent words in recent years. We have heard the saying that in the next coming 20 years, the most energy consumed thing is not industry, not transportation, but our house. The energy consumption of doors and windows occupies a large proportion of the houses’ energy consumption.
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 300~500USD per year according to your whole building’s fenestration areas. That’s a real bargain compared to choosing a regular glazing set.

Guarantee 0 Damage Packaging , Detailed Instructions for Easy Installation

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 need 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 .
