Building energy conservation innovation continues, new materials improve building insulation performance

During the season of renovation, people began to browse the market to select building materials. Many people have the feeling that after they stop heating every year, they don't like to stay in the house for a certain period of time because the house is colder than the outside. In the summer, they don't like to open the curtains anymore, because then the house will warm up quickly. In fact, this is mainly due to poor thermal insulation of the walls and windows of the house, which in turn leads to high energy consumption and high consumption of the building.

At present, there are many products that have been used to improve energy efficiency in buildings. However, because of the sales channels, they have not yet been popularized in the retail market. Consumers often want to use them to search for them. In this issue, Xiao Bian has collected some building materials products that can be used for household thermal insulation and energy conservation in the construction materials exhibition to provide materials for consumers' choices.

Apply a layer of “foundation” Curtains change curtain Although curtains that play a role in heat insulation often have poor permeability and affect indoor viewing, curtain fabrics that can insulate and control light without affecting viewing Come out. It is understood that this kind of curtain fabric is composed of 30% PVC and 70% polyester fiber, and has a very thin layer of aluminum alloy coating, which can greatly reduce the probability of penetration of solar thermal energy into the room, and at the same time guarantees Good perspective. Because of the aluminized coating with reflective thermal energy, curtains using this type of fabric can also prevent the loss of heating in the winter and protect the stability of the thermal environment in the room.

Usage Tip: Since the curtains have aluminized coating, water will oxidize and lose function. Therefore, do not clean with water when cleaning, and avoid wiping with a damp cloth. In addition, in order to ensure that the metal coating is effective for a long period of time, storage methods such as folding, which may cause the coating to break, should also be avoided. It is reported that the use of aluminized coating curtains is 20% -30% more expensive than conventional high-end curtains.

Shutter curtains When the sandwich "sandwich window" security window is an important passage for indoor light, it is also the largest cold bridge, and there is also a certain degree of insecurity. In order to improve the thermal insulation properties of windows, more and more families have chosen double-glazed insulating glass. However, according to reports, in order to maximize the reduction of consumption and improve the safety performance of the window, it is possible to add a ventilated roll-up blind on the basis of a double-layered insulating glass window. The vent holes on the roller shutter blades can adjust the lighting and ventilation of the windows at will. In addition, since the curtain of the device is buried in the wall and is fully closed when it is closed, it also has certain anti-theft performance and increases the safety of the living room.

Tips: According to professionals, the system is generally electric, so the line should be designed in the early stages of renovation, and requires professional installation, otherwise the open-line design will affect the appearance of the room. In addition, if the area of ​​the window is less than 4 square meters, it is recommended to design it manually, and reducing the cost does not affect the use. It is reported that due to the use of different materials, the cost of the roller shutters in the range of 300-1000 yuan / square meter.

Applying a layer of “mask” glass to prevent theft will not break the window glass film can block the heat of the sun into the room in the summer, but in the winter can reduce the heat energy to the outside, thus reducing the heat loss of the house has been gradually familiar with consumers. At the same time, colored, translucent, opaque, patterned decorative film also came into being. With the increasingly mature construction film technology, the thermal insulation film has a safety and explosion-proof performance in addition to the thermal insulation function. According to reports, a glass film formed of a special adhesive on a multi-layered polyester film can form an invisible barrier on the window, which can effectively prevent the destruction and damage caused by glass splash caused by natural disasters, theft and intrusion. , Fixed damaged glass in the frame, especially for families with children and elderly living for a long time.

The use of tips: As the application of glass film in automotive glass is more common, resulting in the emergence of some sales traps, so consumers must pay special attention to the salesperson in the functional display, whether to use double-film fake; whether to use different colors Glass falsification; whether to change bulbs with different wattage when doing insulation experiments, etc.

Add "glass beads" thin coating thermal insulation to increase the insulation properties of the house, their home can do in the renovation is often to increase the insulation layer, however, the traditional insulation material has a certain thickness, increase the insulation layer means to give up certain use Area, but also, there is a certain degree of security risk. At present, in addition to the decorative effect, the paint products have some new properties, such as air purification, thermal insulation and so on. According to professionals, the core technology of thermal insulation coating products is to add hollow ceramic microbeads or glass microspheres in the coating to achieve infrared radiation heat radiation, prevent heat from passing through various material surfaces, and maintain the stability of the thermal environment in the home. The excellent thermal insulation coating can replace the traditional thermal insulation wallboard in southern China, saving the indoor use area and effectively preventing the heat from passing through the wall. In northern China, this product can play a role in increasing indoor comfort on the basis of decorative walls.

Tips for use: The addition of micro bead fillers in paints is the key to thermal insulation of coatings. However, many of these products in the market are not as hard as the technology and the actual results are far from satisfactory. Therefore, when choosing, you can ask the salesperson to specifically introduce the technical parameters of the product. The higher the beading rate of the ceramic beads, the better the effect. In addition, the cost of the use of "Cedunton" nano-thermal insulation coatings exhibited at the exhibition was approximately 30-40 yuan per square meter.
