When buying windows and doors, their thermal insulation performance is the focus of our consideration. In order to have a better thermal insulation effect, most people would rather be more expensive, and will choose products filled with insulation cotton in the door and window cavities. In this regard, some people think that it is an IQ tax!
In fact, the design of built-in thermal insulation cotton in the door and window profile cavity is mainly to improve the overall thermal insulation and thermal insulation performance of doors and windows. The principle is: there is a relatively large temperature difference between the aluminum on both sides of the door and window (one side indoor, one side outdoors), and this temperature difference will drive convection and radiation, resulting in energy loss.
By filling the cavity with thermal insulation materials, such as insulation cotton, polyurethane foaming agent, etc., this heat transfer can be effectively prevented, thereby reducing the energy consumption of refrigeration or heating equipment, and achieving the effect of energy saving and improving indoor comfort.
This design can also provide a certain amount of sound insulation. Because the occurrence of convection phenomenon will bring noise problems, filling the cavity with insulation material can play a good barrier role, so as to play a good noise reduction effect.
On the whole, the built-in thermal insulation cotton of the door and window profile cavity is an effective means of energy saving and sound insulation, and it is not an IQ tax, but its effect needs to be determined according to the specific design and use environment. It is recommended to have a detailed consultation with a professional sales staff at the time of purchase to ensure that the selected product can meet your needs.
Of course, it should also be noted that it is necessary to choose a reliable big brand, so that the quality, after-sales service and other aspects are more guaranteed, and you can buy and use it with confidence.
