The temperature suddenly dropped in winter, and some places also began to snow. With the help of indoor heating, you can wear T-shirt indoors only by closing the doors and windows. It is different in places without heating to keep out the cold. The cold wind brought by the cold air makes the places without heating really worse. The indoor temperature is even lower than the outdoor temperature.  

And it is really important for the south to have doors and windows that can resist the cold wind and cold air. So how to choose the system doors and windows that can effectively save energy and heat in this winter? How to insulate the system doors and windows? Why can we keep warm?

1) Insulating glass
The area of a door and window glass accounts for about 65-75% of the area of the door and window, or even more. Therefore, the effect of glass on the thermal insulation performance of the whole window is also increasing, and we often do not know the difference between ordinary single-layer glass and insulating glass, three-glass and two-cavity, and laminated glass.
Ordinary single-layer glass has its upper limit in terms of thermal insulation and sound insulation because it has only one layer. In contrast, insulating glass has glass inside and outside, and the glass is also equipped with good insulation and heat insulation cotton. Glass is also filled with argon (Ar) gas, which can obviously make the temperature difference between indoor and outdoor. In summer, it will be very cool in the high outdoor greenhouse, on the contrary, in winter, it will be warm in the outdoor cold condition.

2) thermal break aluminum profile
Not only that, the thermal insulation performance of doors and windows is closely related to the overall sealing of doors and windows, but the difference between the sealing performance of doors and windows depends on the quality of the adhesive strip, the penetration method, and whether there is an isotherm in the same line (or plane) inside the profile. When the cold and hot air inside and outside the doors and windows exchange, the two broken bridges are in the same line, which is more conducive to forming an effective cold-heat bridge barrier, which can reduce the cold and heat conduction of air.
For thermal break aluminum doors and windows, the indoor temperature will not change too fast in winter. In addition, it can effectively reduce the loss of indoor heat, reduce the use time and power of indoor heating, and reduce power consumption. Hot weather also saves energy and insulates heat, so choosing a good set of doors and windows will improve the quality of life.

3) Window sash sealing structure
The internal sealing structure of LEAWOD doors and windows adopts EPDM composite sealing waterproof adhesive strip, PA66 nylon thermal insulation strip, and multiple sealing structures between the window sash and window frame. When the window sash is closed, multiple sealing isolations are used to prevent cold air from spreading from the gap to the room. Make the room warmer!
