How much heating costs can be saved in winter?
The thermal insulation performance of light steel villas is usually good, which can save a certain amount of heating costs in winter. The following is a specific analysis:
Reasons for good thermal insulation performance
Application of thermal insulation materials
Wall insulation: The walls of light steel villas generally use high-efficiency thermal insulation materials, such as glass wool, rock wool, extruded polystyrene foam board (XPS), etc. These materials have extremely low thermal conductivity and can effectively prevent heat from being lost through the wall. Taking glass wool as an example, its thermal conductivity is usually around 0.035W/(m・K), which can greatly reduce the heat transfer capacity of the wall.
Roof insulation: The roof will also be paved with corresponding thermal insulation materials to form a good thermal insulation layer to reduce the dissipation of indoor heat to the outside world. At the same time, some light steel villas will also use ventilated roof systems to take away some heat through air circulation to further improve the thermal insulation effect.
Ground insulation: For the ground, insulation boards and other materials may be used to prevent heat from being transferred to the underground through the ground. Especially in cold areas, this measure can effectively improve the indoor thermal insulation performance.
Good sealing
Structural features: The structural components of light steel villas can achieve good sealing effects through special connection methods. For example, sealing strips, sealants and other materials are used to seal the wall panels and roof panels to reduce air infiltration.
Door and window sealing: The matching doors and windows usually also have good sealing performance, using multiple sealing strips, broken bridge aluminum and other materials and technologies to effectively prevent outdoor cold air from entering the room and keep the indoor temperature stable.
Heating cost savings
The heating cost that light steel villas can save in winter varies depending on many factors, such as the climate conditions in the area, the specific insulation measures of the house, the heating equipment and methods used, and the heating needs of residents. Generally speaking, compared with traditional brick-concrete structure houses, light steel villas may save 30% - 50% of heating costs in winter.
In some extremely cold regions, if the monthly heating fee for a traditional brick-concrete structure house is about 500 yuan, a light steel villa may only cost 250-350 yuan per month. In areas with relatively mild climates, the saving ratio may be slightly lower, but it can also reach about 20%-30%.
