Strengthening the inner wall insulation roof can not fall
In general, the warmth of the house adopts internal wall insulation and external wall insulation. The internal and external wall insulation has been completed during the construction of the main structure of the builder, and the internal wall insulation can be further processed during the decoration. According to the current director of decorative engineering Hu Zengguang, the insulation wall is generally 3cm-5cm thick, mainly assembled using lightweight insulation boards, or can also be used in perlite, inorganic active wall insulation materials, etc. Plastered body. Of course, Hu Chen, Chief Engineer of Canoe Decoration, said that indoor wall insulation can also use phase change materials instead of traditional insulation materials. The smart sandwich of canoe decoration is a kind of phase change material product. Hu Yu explained that the material will be controlled by the phase change point. The wall phase change decorative materials developed around 15°C～25°C can naturally absorb and release solar energy. When the temperature is high during the daytime in winter, the wall materials absorb heat, and the heat is released when the temperature is low at night, so as to automatically add the house. The role of temperature.
In addition, Michaael R. Ashburn, chairman and chief executive officer of Chengyu Energy Co., Ltd., said that during his renovation, his home was built with a 10cm wall insulation from the roof to the wall. Say, although doing so has caused the indoor area to shrink, but compared to before the decoration, the indoor temperature can have the difference of about 10 °C, or value for money. At the same time, Mike said that next time he changes, he will consider thickening roof insulation, because the roof of a single-family house or top floor is also the main part of heat dissipation.
Nowadays, decorative insulation panels have emerged in the decoration market. The cost is around RMB 100 per square meter. Consumers with smaller indoor areas no longer have to worry that thickening the insulation will reduce the indoor area because the integrated board can help. You reduce the thickness of the wall covering layer, while protecting the indoor temperature without affecting the beauty of the room.
Keeping the temperature of the window controlled by alternating hot and cold
The doors and windows were the largest cold bridges in the house. So, when Mike was doing his own renovation, he replaced the windows with double or triple glazing. In the south-facing window, an automatic sunshade was added, but he did not. Choose to stick a glass film because he wants his house to absorb solar heat more fully in the winter and supplement the room temperature.
In addition, Hu Hao said that the original old house, the heating is installed under the window, that is the correct installation location. Because the cold air outdoors passes through the window into the room, if the heating directly under the window is heated, the air curtain can be formed by the action of the heating, and the uneven cooling and heating inside and outside the window can be adjusted to maintain the room temperature. But now for the sake of beauty, most home heating is not installed under the window, or directly from the floor-to-ceiling windows. Therefore, it is recommended that consumers can consider using a door and window frame radiator in the renovation, so that the window frame into a heating, both beautiful and can effectively reduce the indoor and outdoor temperature difference, reduce heat and heat exchange, maintain room temperature, reduce energy consumption.
In addition, Hu Zengguang reminded consumers that in the old house, many of the insulation materials around the windows have been detached. The most obvious feature is that there are gaps around the windows. It is recommended that consumers must use thermal insulation materials to cover the temperature of the windows. Of course, for the sake of beauty, you can paint with the same color of the exterior wall.
Walk-in balcony must do three more insulation
When there is a floor-to-ceiling window and a bay window in the house, check whether the gap between the window and the wall is full or not. If there is any gap, fill it with heat insulation material to avoid air leakage.
In addition to floor-to-ceiling windows and bay windows, many families now choose to open the balcony and the room. However, due to the lack of isolation between the windows and walls, the insulation coefficient of the house will suddenly drop and the temperature will not be guaranteed. In this regard, Hu Zengguang said that the general construction of the balcony does not do thermal insulation, so in their own decoration, in order to keep warm in the balcony wall, roof, etc. to do thermal insulation. The floor can be made of light bricks or ceramsite concrete padding, and the wall surface can be affixed with polystyrene board or extruded board, and plasterboard or cement pressure board can be used to treat the paint or wall tile. The top surface can be treated with some ceilings, such as gypsum board ceilings, aluminum buckle board ceilings, sauna board ceilings and so on.
Refurbished old homes must not be "beautiful"
Many consumers will consider how to do more beautiful when refurbishing their old homes. However, to decorate their homes, they must not “respect the grace and not the temperatureâ€. Hu Zengguang said that at present, it has not been found that the house is not warm due to unreasonable house structure, but many families have low indoor temperatures due to the small heating area of ​​the radiator. Therefore, when the old house is refurbished, it reminds everyone not to look beautiful. Or increase the size of the living room, in the change of the indoor structure will be light wall, insulation wall and even some of the heat removed without supplemental warmth.
In addition, if the north-facing house is particularly cold in the winter, it is recommended to replace the window with a double-glazed plastic window or to convert the heating into a larger number of square meters for heating. To do some insulation treatment, you can choose to stick polystyrene board or extruded board outside the plasterboard insulation method.
