Is the thermal performance of ordinary wooden houses good?

A prominent feature of the wooden house is its strong thermal insulation ability. Wood is a porous material with low thermal conductivity. Wood-structure houses make use of the principle of interlayer insulation and air barrier, which makes the insulation capacity of the houses very good. Wood and gypsum board are both poor conductors of heat, and the frame structure combined with them forms a relatively closed indoor space. Therefore, whether heating in winter or cooling in summer, the energy consumption of wooden buildings is only 1/5 of that of brick-concrete buildings, which greatly saves energy costs. Because the wall is equipped with thermal insulation and sound insulation material-glass fiber rock wool, the thermal insulation ability of wooden structure houses is improved more effectively. The thermal insulation effect of glass fiber rock wool with the same thickness is 8 ~ 12 times that of concrete, and its noise reduction and sound absorption effect is 4 times that of concrete. The structural house adopts the structural design of high-efficiency thermal insulation glass wool, and its moisture-proof performance can even reach about 10 times of that of brick-concrete structure. At the same time, wood itself has the function of absorbing and releasing water, which can alleviate the change of indoor humidity. The plate structure with excellent air permeability and thermal insulation gives people a refreshing, comfortable and pleasant feeling. First of all, in order to achieve satisfactory cooling and heating effect in brick-concrete buildings, dual-frequency power supply host is essential. Secondly, due to the rapid heat dissipation of the house, the machine is turned on for a long time every day, and the monthly electricity bill is at least doubled. In contrast, wooden villas can save energy by 60%. In the relevant codes of our country, regarding the thermal insulation performance, if the wooden house is built according to the national standard, its thermal insulation effect is ideal. By simple comparison, according to the experimental data of the national designated laboratory, the thermal insulation performance of the light wooden wall is more than twice that of the concrete wall with the same thickness.
