In the last quarter of each year, it is often the time for developers to focus on housing. Acceptance and inspection of the house must not be sloppy, and it is not enough just to feel it.
The amount of heat emitted in the winter through the outer wall of the building reached 20% of the total. In order to buy a truly "warm" house, the wall must be carefully examined.
External wall insulation see benzene plate thickness
For a long time, house prices in the mountains have been lower than those in other places, and they are not easy to sell. The reason is that in winter insulation, although benzene board insulation technology has been widely used in recent years, most people still do not. Rest assured, try not to buy a house in the mountains.
Mr. Wang, who had just bought a house, told reporters that in fact, not only the house of the mountain, but also the insulation of other real estate properties is difficult to estimate. It is not necessarily certain that the benzene board is not cold, but also depends on the benzene board of the external wall insulation. How thick is it to meet the eligibility criteria?
Industry insiders told reporters that according to the standards of the northeast region, the thickness of benzene plates used for exterior wall insulation is generally between 8 and 10 cm. Most buildings in Shenyang are 8 cm, and even colder ones reach 10 cm. Harbin should be thicker, these are hard standards.
Heat Dissipation Looks at the Combination of "Cold Bridge"
The so-called “cold bridge†refers to the part of houses, such as windows, doorways, ring beams, and balcony pillars, which are connected to the outside world. These parts are directly exposed to the impact of cold air and are scattered in large numbers due to the lack of wall and external wall insulation systems. Indoor temperature.
When watching, pay close attention to the tightness of the joints between the window, the door and the wall, and if possible, whether or not there is an additional inner insulation layer in these places.
According to experts, even if the “cold bridge†parts are tightly integrated, it is difficult to ensure less heat loss. A more advanced approach is to additionally increase the inner thermal insulation layer at these easily dissipated heat sites, which is more reassuring. Insulation glue is poured into the joint gap. If you encounter such practices during the viewing process, only one can determine the house's insulation performance is better.
Make sure temperature looks at energy-saving materials
After seeing the benzene board and checking the doors and windows, it is necessary to pay attention to the “additional†premium accessories, that is, the recently popular high-tech energy-saving and environmental protection materials. There are many kinds of energy-saving and environmental-friendly materials, and it is more common to use “three glass†in terms of heat preservation, that is, three-layer vacuum glass. The “three glass†here is not as simple as turning a layer into three layers. It is not only that the thickness is thicker than ordinary glass and the process is more complicated. The glass and glass are completely vacuumed. The effect of heat insulation and sound insulation is necessary. It is several times better than ordinary single-layer or two-layer glass.
Of course, if you are buying a second-hand house, this requires us to be more careful. Pay attention to the temperature difference between indoor and outdoor, and whether there are signs of “long hair†in the wall of the house, so as to infer the overall insulation effect of the building.
