Casement window is the most common kind of window, which is divided into two types: inside opening and external opening. Casement window, the window sash is combined with the window frame through hinge, and the window sash can be rotated to open. This kind of window has the advantages of simple structure, the whole window can be opened 100%, the air tightness is good when closing, and the building thermal performance is high. In today's increasingly high demand for building energy saving, the casement window will become the mainstream of the market. The disadvantage of casement window is that the sash should occupy a certain space after opening, so it should not be used when there is not enough space to accommodate the open window in some special narrow positions. The following and small make up together to understand the aluminum alloy casement window related knowledge.
Materials for aluminum alloy casement window
Aluminum alloy casement window main materials include three aspects: aluminum profiles, glass, hardware. Owners often pay more attention to the thickness of aluminum profiles and glass when choosing products, but the requirements for hardware are not very high, which is not comprehensive. In fact, the national requirements for aluminum alloy casement windows have certain standards. The thickness, strength and oxide film of high quality aluminum alloy casement window can meet the national standard.
Processing of aluminum alloy casement window
In addition to material to meet the quality requirements, processing is also a very important part. Because the technical content of aluminum alloy casement window is not high, the degree of mechanization is not high, most of them still rely on the manual operation of installation workers, which requires operators to have good product quality awareness.
Appearance of aluminum alloy casement window
Owners usually pay attention to the appearance of the products and the decorative patterns of the glass when purchasing high-end aluminum alloy casement window products, but often despise the composite film on the surface of the aluminum alloy casement window. This kind of composite film is formed by artificial oxidation film coloring, which has corrosion resistance, wear resistance, high gloss, and also has a certain fire protection function. Therefore, more comparison should be made when purchasing aluminum alloy door and window products Similar products.
Performance of aluminum alloy casement window
The performance of aluminum alloy casement window has different emphasis due to different application scope, but the following aspects should be considered generally:
1. Strength, which is mainly reflected in the selection of aluminum alloy casement window profiles, whether it can withstand ultra-high pressure;
2. Air tightness, mainly reflected in the window structure, whether the inner and outer frame structure of the window is tight, whether the frameless balcony window is tight and airtight;
3. Water tightness, mainly to assess whether there is water accumulation and leakage in aluminum alloy casement windows;
4. Sound insulation, which mainly depends on the sound insulation effect of insulating glass and other special structure of sound insulation and air tight strip, as well as the durability of other doors and windows such as opening and closing force, heat insulation, durability of nylon guide wheel, durability of opening and closing, etc. The performance of aluminum alloy casement window mainly depends on the above three aspects.
