Aluminium wood energy-saving doors and windows are expected to become market darlings

On November 23rd, the 10th China International Door & Window Curtain Wall Expo was held in the New China Exhibition Hall. Nearly 500 door and window companies from across the country gathered in the exhibition hall of 55,000 square meters. At the scene, the reporter found that most of the door and window exhibitors this year have implemented the concept of “energy saving” and placed energy-saving doors and windows such as aluminum-wrapped wood in the prominent position of the exhibition hall.

As the representative brand of aluminum-clad wooden doors and windows, Philharmonic House designed the exhibition hall as “Chinese window, world window, and future window”, demonstrating three different types of energy-saving doors and windows, representing energy savings of up to 75%, 85%, and 100% respectively. % of door and window products. Taking an energy-saving aluminum enclosure door and window of 85%—Nordic Spring series as an example, the “single-frame double-fan and three-glass window” structure has a thickness of nearly 10cm, while the multi-layer composite glass, environmentally-friendly wooden frame and trapezoidal profile Structures, imported rubber strips and other technologies will make the heat transfer coefficient of this product reach 0.9.

Beijing's "Energy Efficiency Design Standard for Residential Buildings" (DB11/891-2012) will be formally implemented on January 1, 2013. The doors and windows industry representing building envelope structures will also encounter energy conservation limitations.

At the 10th China International Door and Window & Curtain Wall Expo held on November 23rd, Philharmonic and other door and window companies have integrated energy conservation concepts into their products to achieve mutual PK energy performance.

In addition to the Philharmonic House, many brands participating in the exhibition are showing great energy-saving performance. For example, Jingwu Doors and Windows has set up a variety of conduction stability experimental environments to verify the energy efficiency of products; Milan's window has imitated Italian energy-saving brands and has achieved a domestic heat transfer coefficient of 1.0, which is rare in China.

According to industry sources, in this energy-saving elimination tournament, the original aluminum alloy that will occupy the mainstream will gradually withdraw from the market, and new types of energy-saving doors and windows such as aluminum-clad wood will be popular, but whether or not the price can be lowered is the main bottleneck for its popularity.

Energy-saving doors and windows have become the protagonists at the show. One of the most important factors is that, starting from January 1, 2013, Beijing will implement the “Design Standard for Energy Efficiency of Residential Buildings”, and traditional windows and doors, such as aluminum alloys, that fail to meet energy-saving standards will gradually withdraw from the market. It is replaced by new energy-saving doors and windows.

During the “12th Five-Year Plan” period, Beijing’s requirement for building energy efficiency was raised from 65% for energy conservation to 75%. The Beijing Municipal Planning Commission and the Beijing Municipal Bureau of Quality and Technical Supervision jointly released the “Energy-saving Design for Residential Buildings” on June 14 this year. In the "Standards", although 75% of this index is not included, a clear requirement has been made for the "K value" of the heat transfer coefficient, which serves as the standard evaluation function for doors and windows. According to regulations, the "K value" of the door and window products should be maintained at Within the range of 1.5-2.0, but according to industry analysis, the K value of the heat transfer coefficient of most doors and windows in China is between 2.0 and 2.8.

At present, there is still more than one month before the implementation of the new standard on January 1, 2013. All doors and windows companies have started to launch their own energy-saving products and warm up for next year's energy-saving limit. Some brands also meet foreign energy-saving requirements, such as Aileola Exhibition. The "World Window" level products have reached the energy saving standards for doors, windows and doors in Denmark, the United States, and Sweden.

Aluminium wood needs to break the price bottleneck

According to statistics, the energy consumption of buildings accounts for nearly 1/3 of the total energy consumption of the city, and the advantages of thermal insulation of doors and windows play a key role in reducing energy consumption. Energy-saving doors and windows will become the mainstream of the market in the future.

However, energy-saving doors and windows represented by aluminum wrappers face price bottlenecks. Compared with the price of one or two hundred yuan per square meter of aluminum alloy doors and windows, the price of aluminum-clad wooden doors and windows of 2000-4000 yuan per square meter is still hopeless for most consumers. Taking Philharmonic House as an example, its main aluminum-wrapped wood products are mainly used in villas and high-end real estate. For the vast residential market, it is necessary to popularize energy-saving doors and windows such as aluminum-wrapped wood, not only to test the spending power, but also not every one. Brands can ensure the production of qualified energy-saving products.

Meng Xiangbin, general manager of Beijing Philharmonic Building Energy-Saving Products Co., Ltd., said that energy-saving doors and windows are not just a simple functional design. It is a systematic project. A good energy-saving door and window is made of frame material, glass configuration, structural design, and processing technology. Such factors as precision, these factors will eventually reflect the heat transfer coefficient is good or bad.
