Significance of thermal insulation

Insulation materials play an important role in building energy conservation. Under the condition of ensuring the improvement of building comfort and quality of life, energy is used reasonably and effectively throughout the use of the building, that is, energy consumption is reduced and energy efficiency is improved. In ordinary houses, although the required indoor temperature can be maintained by relying on heating equipment to supply more heat, the heating heat supply must be greatly increased.

30% of the energy used for heating in winter and cooling in summer is not used by the human body, but is lost to the outdoors through windows and walls, which increases the heat island effect and wastes energy. At present, all international energy-saving buildings have adopted building insulation technology in their walls. Good thermal insulation performance can also bring the following benefits to buildings:

1. Prevent damage to the building structure caused by condensation inside the building shell. If there is not enough insulation in the building, the high relative humidity in the building will cause condensation and eventually mold. Insulation materials ensure that the surface temperature of the room is not lower than the critical temperature, thereby avoiding condensation and mold formation.

2. Provide a comfortable thermal environment for people living in the building. The insulation layer reduces the heat exchange through the building shell, so that the heating and cooling machines can achieve the same indoor air temperature with less energy input. In winter, it can prevent the loss of indoor heat, and in summer, it can play a role of insulation. Thus, it ensures that the indoor temperature is warm in winter and cool in summer, and significantly improves the indoor thermal environment.

The transfer of heat is caused by the temperature difference between indoors and outdoors. Heat can be transferred by heat conduction, heat convection or heat radiation. The transfer rate is closely related to the nature of the propagation medium. Heat is lost or absorbed by the transmission through the ceiling, walls, floors, windows and doors. This heat reduction and gain is usually unwelcome. Because it not only increases the load of the HVAC system and leads to more energy consumption, but also reduces the thermal comfort of people in the building.

Strengthen building insulation, use appropriate insulation materials and design for buildings, improve the heat transfer resistance of the envelope structure (or reduce the heat transfer coefficient) to meet the requirements of the current national standards and specifications. When choosing a product to install, two topics that homeowners usually discuss are cost and R value. R value is the insulation value of the product. The higher the R value, the better the insulation value. An airtight, highly insulated building envelope is the most effective way to reduce your home's energy consumption and carbon emissions, so deciding on the type of insulation material to use is crucial.
