Different regions have different home selection methods. High-end villas mainly use aluminum-clad wood doors and windows. Different types of home doors and windows have different functions. Some have thermal insulation functions, some have sound insulation functions, and some have waterproof and fireproof functions. The methods of purchasing different types of doors and windows are also different. So what are the types of doors and windows for home use? How to choose doors and windows for your home?
The main categories of household doors and windows are as follows:
1. Aluminum alloy doors and windows
Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fan materials. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include doors and windows that use aluminum alloy as the force-bearing rod (a rod that bears and transmits its weight and load) as the base material and wood and plastic composite doors and windows, referred to as aluminum-wood composite doors and windows, and aluminum-plastic composite doors and windows.
2. Solid wood doors and windows
Solid wood doors and windows are finely crafted and expensive. In recent years, with the increasing popularity of green and environmentally friendly building materials products and changes in consumer concepts, solid wood doors and windows, which were once abandoned by the market, have made a comeback and are favored by home decorators. Most of these solid wood doors and windows are fine in workmanship, noble and elegant, or European-style carvings, Japanese-style combinations, or ancient charm still exists, or simple and bright, interpreting different moods of the room.
3. Plastic steel doors and windows
Plastic steel doors and windows are made of polyvinyl chloride (UPVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., and are extruded into shaped materials, and then cut, welded, or screwed Made into door and window frame fans, equipped with sealing strips, tops, hardware, etc. At the same time, to enhance the rigidity of the profile, steel lining (reinforcement ribs) needs to be filled in the profile cavity that exceeds a certain length. The portal window is made in this way, called plastic steel doors and windows.
4. Stainless steel doors and windows
Stainless steel doors and windows are doors and windows made of stainless steel plate materials. They have the same appearance as ordinary doors and windows. The main materials are stainless steel + wooden boards as panels, so they can play the role of anti-theft doors and windows. Various door decorations can be made using molds. It is widely used in residential areas and is generally used as the entrance door to protect the inner door from damage.
5. Broken bridge aluminum doors and windows
Broken bridge aluminum doors and windows use thermally insulated broken bridge aluminum profiles and insulated glass, which have the functions of energy saving, sound insulation, noise prevention, dust proofing, and waterproofing. The thermal conductivity K value of broken bridge aluminum doors and windows is less than 3W/㎡·K, which reduces the heat loss by half compared with ordinary doors and windows, reducing heating costs by about 30%. The sound insulation is more than 29 decibels, and the water tightness and air tightness are good, both reaching national standards. A1 category window standard.
6. Aluminum-clad wood doors and windows
It is a high-end door and window currently on the market. The price is relatively high, but it has excellent performance, good heat insulation, heat preservation, windproofing and dust proofing, sound insulation, and other properties. It has a long service life. Generally, there is no problem for about 30 years. Aluminum-clad wooden doors and windows The inner wood is composed of aluminum profiles and imported wood, which is beautiful, fashionable, and natural. Aluminum-clad wood doors and windows have various compatibility characteristics. Aluminum-clad wood doors and windows add new technologies to them while retaining some of the features and functions of traditional pure solid wood doors. It not only retains the tradition but also has innovations. The main stress-bearing structure of the external aluminum is a thermally insulated bridge-broken aluminum alloy. As for the inner wood, various pure solid wood along-grain laminated lumber can be selected according to customer needs. On this basis, strong compressive and flexural strength is achieved. Compared with aluminum alloy doors and windows, aluminum-clad wood doors and windows are lower in cost and more economical. The outer aluminum layer originated from Europe and the United States and is highly fashionable. In addition, many modern metal coatings can be applied to various architectural styles.
In addition to the above 6 types, there are also high-end door and window categories such as wood-clad aluminum doors and windows, and copper-clad wood doors and windows.
Broken bridge aluminum doors and windows purchasing knowledge:
1. Choose original products
Many low-quality aluminum materials on the market are processed from recycled scrap aluminum, and the color of the window surface often shows large color differences and the thickness is not up to standard. The product quality cannot be compared with the original products from major manufacturers. Pure aluminum ingots are used to ensure product quality.
2. Hardware selection
To choose high-quality hardware, manufacturers must obtain goods directly from hardware manufacturers. At present, the accessories used for broken bridge aluminum doors and windows are of varying quality. Cheap accessories often fail to open or close after a few years, causing rain leakage, wind intrusion, and lack of sound insulation. Condition.
3. Profile wall thickness
Generally speaking, when making home decoration products, door, and window factories or processors mostly choose products with a high yield rate, that is products with a relatively thin wall thickness, to reduce the cost. Currently, many aluminum alloy profiles on the market have a wall thickness of only about 1.2, which is lower than the national standard. The thickness of broken bridge aluminum doors and windows should be greater than or equal to 1.4mm in strict accordance with the national profile.
4. Look at the insulation strips
Insulation strips are made of PA66 nylon as a component of broken bridge aluminum doors and windows, which is stipulated by relevant standards. However, many manufacturers in the current decoration market use cheap PVC plastic heat insulation strips, which will seriously affect the service life and safety of the product.
Knowledge on purchasing aluminum-clad wood doors and windows:
To identify the quality of aluminum-clad wood doors and windows, we must examine various aspects such as frame material, glass, sealing, and paint of aluminum-clad wood doors and windows:
1. What we usually call good windows are smooth linear shapes, perfect and flat paint surfaces, and small wood color differences. Therefore, you must pay attention to the identification of these details when purchasing.
2. Sealing strips must have good elasticity, flexibility, and anti-aging properties. The best choice is high-quality sealing strips with high EPDM content. The strips must be installed tightly at the corners and the lines must be smooth. Need to distinguish between increased strength and air tightness.
3. For related operations, the operation must be a hardware structure with strong load-bearing capacity. It must be opened and closed flexibly, and the overlap must be rigorous, with good air tightness and hydrophobicity. The hardware installation must be strong and the handle must not shake. You can easily achieve the effect of opening and closing.
4. Identify the diagonal joints of glass battens and wooden battens that need to be tightly connected. First, the gap should not be larger than 0.5mm, and it needs to be flat without any bumps. Secondly, the corners of the outer aluminum 45-degree angle set should be flat without any uneven bumps. Phenomenon, the relative gap must be less than 0.5mm.
5. Observe the paint. The choice of paint must be a special paint for doors and windows. The current market situation requires the use of water-based paint, which must have good texture and airtightness, resist UV rays yellowing, and fading, and must be sprayed evenly without color difference and dust-free. It is relatively good to control the color difference at wood joints within 0.2°.
6. The overall thickness of aluminum-clad wood doors and windows needs to be appropriate, and the overall thickness of the profile cannot be less than 14mm. Otherwise, the strength of the outer aluminum may be too low, and the outer aluminum may easily deform or fall off during use, which will affect the use of the window.
